- OPEN ACCESSIn Canada, recent advances towards reconciliation have introduced new collaborations between Indigenous and non-Indigenous governments, including for species-at-risk recovery planning. During these collaborations, Indigenous Knowledge (IK) is often requested, however, clear expectations of what IK is being sought and how diverse knowledge systems will be woven to produce tangible benefits to species recovery are often limited. Here, we provide a case study of a two-stage process to identify and collect IK components that can aid whudzih (caribou) recovery planning. First, we surveyed non-Indigenous government professionals involved in caribou initiatives to specify what IK would benefit recovery planning. Responses were used to guide the development of semi-structured interview questions. Interviews were conducted with knowledge holders from Lhtako Dene, a Southern Dakelh Nation in British Columbia, Canada with historic socioecological ties to caribou. Responses of government professionals highlighted 24 topics for caribou recovery, and interviews with Lhtako Dene knowledge holders revealed strong linkages between ecological and social information types. In some cases, the IK requested was not available from knowledge holders. Collaborations for caribou recovery would benefit from clarity on expectations and outcomes of IK sharing. We suggest that structured processes that respectfully facilitate IK requests and collection become commonplace in species recovery planning.

Status quo frameworks are highly Eurocentric and narrow in scope protecting; biodiversity conservation in many parts of the world and reflect a kind of dichotomized conservation that has created and perpetuated patterns of poverty, food insecurity, and socio-economic marginalization, particularly among Indigenous Peoples. By dichotomized conservation, we mean an approach to conservation that is not taking into consideration the intrinsic interdependence of environment, people, and all the species. It is the management of conservation of different ecosystems and species separately. This framework is opposed to the Indigenous approach to conservation in which people cannot think about their health and well-being without thinking about the health and well-being of Mother Earth. New conceptualizations of biodiversity are needed that are holistic in nature and confront these historical and systemic patterns of exclusion of Indigenous Peoples. - OPEN ACCESSThe environment is changing under the impact of climate change, but many Ontario land trusts still operate with the goal of maintaining historic patterns of biodiversity. This misalignment of conditions and goals may render the important work of these land trusts less effective. To help improve this situation, we conducted several knowledge translation activities to inform Ontario land trusts about possible climate change adaptation options. Throughout the knowledge translation activities, we collected participants’ comments and examined them with hypothesis and descriptive coding to reveal data about challenges and facilitators, which we grouped into themes with pattern coding. The results helped us identify challenges and facilitators that land trusts experience when participating in climate change knowledge translation and attempting to adapt to climate change. The challenges include a lack of resources, limited technical skills and species knowledge, and competing priorities and perspectives. Facilitators include a general interest in climate change, use of tools for adaptation planning, and resource sharing. To increase climate change adaptability in the Ontario land trust sector, we recommend greater collaboration between land trusts, modest modifications to existing conservation actions, shifting from passive to active conservation, and moving from species-level to community and ecosystem function conservation goals.
- OPEN ACCESSConservation easements (CEs) are a private land conservation (PLC) tool, with landowners voluntarily selling property rights to an outside entity (governmental or nongovernmental). Pioneered in the USA, CEs were operationalized in the late 1980s, and by 2001, legislation had swept across Canada. I asked how did subnational Canadian CE policy develop? I analyzed Hansard records and interviewed government officials, finding coercion from the Federal government and environmental nongovernmental organizations (eNGOs), with transfer being ideologically, geographically, and temporally uneven. CE legislation reveals a fundamental shift in how subnational governments were trying to enhance biodiversity conservation, specifically by legitimizing PLC and non-state partners. Interestingly, this study both confirms, and pushes back against, previous Canadian policy transfer studies. I found a lack of formal subnational policy networks and an increased role of subnational policy innovators unlike previous studies, while the substantial U.S. influence align with older policy cases. ENGOs were the most active proponents to push for CE legislation, not policymakers or foreign states. Ultimately, Canadian federalism creates unique subnational policy arenas that require further study to understand the movement of conservation policy, especially with the crises of biodiversity and climate.
- OPEN ACCESSThe bigmouth buffalo (Ictiobus cyprinellus, Valenciennes 1844) is a long-lived freshwater fish native to North America that is listed as a species of special concern in its Saskatchewan-Nelson range. Little is known about their ecology and behavior, especially in the Saskatchewan Qu'Appelle River system where it faces multiple threats such as habitat fragmentation and competition with invasive species. In this study, we used acoustic telemetry to track the movements of 44 bigmouth buffalo throughout the Qu'Appelle River system in 2017–2019, and 2021, to monitor migration patterns from spring to fall and investigate if any of the five dams were impeding their ability to access either breeding or overwintering grounds. We found that bigmouth buffalo demonstrated minimal use of the river during this 4-year study, instead staying within the confines of a single lake year-round. Our results suggest that bigmouth buffalo in the Qu'Appelle River do not exhibit migratory behavior during nonflooding years. Considering their extended lifespan (>125 years), this could be attributed to their potential bet-hedging strategy for spawning primarily during flood years. The results indicate that bigmouth buffalo voluntarily remained within Buffalo Pound Lake throughout the study period. Whether this behavior was natural or was influenced by modifications to the system’s hydrology requires further investigation.

Reported rates of soil organic carbon (SOC) accumulation in wetlands are markedly higher over recent versus longer timescales, caused by SOC losses through decomposition, paleoenvironmental changes, and recent increases in sedimentation or biomass production. Explaining changes in SOC sequestration rates and determining the time horizon over which high rates are sustained are both critical for accurately measuring the potential for wetland conservation as a natural climate solution. Here, we present analyses on a 4-m core from a riverine-influenced marsh in Big Creek watershed, southern Ontario, to track changes in SOC accumulation regimes. Since wetland initiation ∼5700 years ago, mean long-term (pre-industrial) rates of SOC accumulation were 24 g C m−2 year−1, and recent rates up to four times higher. We demonstrate that elevated recent rates of SOC accumulation are largely explained by more labile carbon in surficial soils, and are sustained for less than a century before transitioning to slower burial rates of predominantly recalcitrant organic matter. However, there are exceptions to this trend, such as when labile SOC was buried intermittently during Holocene Lake Erie highstands. Our research underscores the importance of organic matter type and hydroclimatic context in predicting long-term potential for marsh soils to stabilize atmospheric carbon. - OPEN ACCESSWalleye/ogaa (Sander vitreus (Mitchill)) (hereafter, walleye; ogaa = Ojibwe translation) populations have historically supported important multi-use, harvest-oriented fisheries. Despite intensive management, walleye populations have declined in the midwestern United States raising concerns about the sustainability of the species. Numerous factors have been implicated in walleye population declines, including climate change, habitat loss, invasive species, species-interactions, production overharvest (i.e., harvest consistently exceeding annual production), and changing angler behaviors. These factors have negatively influenced natural recruitment and contributed to depensatory recruitment dynamics. I provide a review and perspective suggesting that the current trajectory of walleye populations is at or nearing an ecological tipping point. Although fish populations are often considered compensatory (i.e., negatively density-dependent), current walleye populations appear prone to depensation (i.e., positive density dependence). My review and perspective suggest that a compensatory management perspective for walleye is misaligned. A change in management towards a depensatory resource focus using ecosystem-based fisheries management and the recognition of walleye fisheries as social–ecological systems is needed for conservation. If compensatory management ensues, walleye persistence will likely be further threatened because many drivers of change are outside of managerial control, and those commonly used within managerial control have seemingly been ineffective for sustaining or rehabilitating naturally reproducing walleye populations.
- OPEN ACCESSIn this conceptual paper, we argue that the assumptions behind laboratory and field studies are that chemical and compositional analysis may reveal structures unseen by means of human observation. However, replacing human observation to make it obsolete is not the purpose of science; if something can be seen, but is not measurable, that does not make it irrelevant. Although science is frequently primarily regarded as a quantitative field, we argue that qualitative data inclusion is necessary determine the consequences of research on Indigenous communities. We discuss key points, including historical and anthropocentric views of science, suggesting that Indigenous Science requires greater wisdom-based knowledge in association with traditional ecological knowledge. We introduce a new conceptual model called “Pollen Sovereignty”, a sister to Indigenous food sovereignty, to begin critical discussions around the ethics of field research and the impacts of research on the environment, land management, and Indigenous communities. That is, through simple scientific concepts, critical thought, and logic new conceptual frameworks and avenues of research, Indigenous knowledges cannot merely be coopted and reused, but respected and valued.

Marine conserved areas (MCAs) can provide a range of ecological and socio-economic benefits, including climate change mitigation from the protection and enhancement of natural carbon storage. Canada's MCA network is expanding to encompass 30% of its Exclusive Economic Zone by 2030. At present, the network aims to integrate climate change mitigation by protecting coastal vegetated blue carbon ecosystems (saltmarsh, seagrass, kelp). Here, we argue that incorporating unvegetated seabed sediments could bring similar benefits. Seabed sediments can store and/or accumulate high densities of organic carbon, and due to their large spatial extent, contain carbon stores orders of magnitude larger than coastal vegetated habitats. We estimate that currently designated MCAs encompass only 10.8% of Canada's seabed sediment organic carbon stocks on the continental margin, and only 13.4% of areas with high carbon densities. Proposed MCAs would cover an additional 8.8% and 6.1% of total stocks and high carbon areas, respectively. We identify an additional set of high-priority seabed areas for future research and potential protection, ranking their importance based on carbon stocks, proxies for lability, and ecological/biological significance. The incorporation of seabed sediments into MCA networks could support climate change mitigation by preventing future releases of stored carbon. - OPEN ACCESS

Facing the global biodiversity crisis, conservation practitioners and decision-makers seek to catalyze wildlife recoveries in their region. Here we examined social-ecological attributes related to threatened species recovery in Canada. First, we used a retrospective approach to compare the trajectories of the original species assessed by Canada’s species-at-risk committee and found that only eight of 36 species now have decreased extinction risk relative to the past. There were no significant differences in human or financial capacity provided for recovery across species doing better, the same, or worse; the only significant difference was whether the primary cause of decline was alleviated or not. Second, when looking at species assessed at least twice between 2000 and 2019 we found that only eight of 422 (1.9%) experienced both increasing abundance and decreasing extinction risk. The defining characteristic of successful recoveries was first alleviating the original cause of decline, which was most often accomplished through strong regulatory intervention. Once declines were halted, practical interventions were highly species-specific. It is instructive to learn from conservation successes to scale resources appropriately and our results emphasize the importance of threat-specific intervention as a fundamental precursor to the successful restoration of biodiversity in Canada. - OPEN ACCESSRegulatory ratchets arise when governance appears to be effective, but actually masks a steady loss of natural capital. This occurs when biases in environmental impact assessment (EIA) systematically underestimate the true impact of large developments, generated by statistical convention fixing α at 0.05 (Type 1 error or false positive rate; i.e., the probability of concluding that a development will have an impact when there is none) while β, the false negative rate (failing to detect a true impact, or Type 2 error), is often fixed at 0.2. This asymmetry (β > α) generates a higher likelihood of mistakenly permitting development than mistakenly preventing it. Beyond statistical bias in EIA, routine environmental regulations are often ineffective due to low compliance, inadequate thresholds, and broad exemptions, which tend to cryptically institutionalize net loss. Measuring bias and inefficiency of environmental regulation is foundational to correcting regulatory ratchets and identifying pathways towards no net loss. Like net loss from major developments, cumulative net loss from inadequate routine environmental protections also needs to be estimated and offset by active habitat restoration; this should be delivered as a core program of resource management agencies, with the goal of fully integrating the mitigation hierarchy into routine natural resource governance.
- OPEN ACCESSCoastal ecosystems face numerous stressors from anthropogenic activities. Furthermore, local stressors that directly impact ecological processes in one location can scale up to have indirect regional consequences. In the case of dispersing marine invertebrates, human activity may impact dispersal and survival rates, which can then alter connectivity patterns and metapopulation dynamics across the seascape. Here, we developed a framework to model metapopulation persistence of seagrass-associated invertebrates in the Salish Sea, focusing primarily on British Columbia, Canada. We combined a biophysical model of dispersal with metrics of habitat naturalness to model how local human activities that may impact dispersal can alter habitat connectivity patterns and potentially impact regional metapopulation persistence. We found that human activities that potentially impact dispersal can reduce population persistence across a region, although the effect varied based on location, population dynamics, and severity of the impacts modeled. The majority of populations, however, remained persistent, suggesting that there are robust and redundant pathways of dispersal that can maintain population connectivity in the face of local disturbances. This study highlights the importance of understanding human impacts and connectivity together in a regional context which could have implications for future marine spatial planning and the effective management of biodiversity.
- OPEN ACCESSThe North American Waterfowl Management Plan (NAWMP) is an international agreement between the Governments of Canada, the United States, and Mexico to coordinate the conservation and restoration of wetlands, associated uplands, and other key habitats for waterfowl and other bird species. To understand public support of NAWMP goals, we conducted a survey of Canadians (n = 2324) and asked about their willingness to make a one-time donation to NAWMP using the contingent valuation method (CVM). Results demonstrate that almost one-third were willing to donate to NAWMP to protect and conserve bird habitats. Parametric analysis of CVM responses provides a mean one-time donation estimate of roughly $33.00 per person. We found that participation in birdwatching is associated with higher willingness to donate to NAWMP, and that this association is stronger among people who participate in multiple outdoor recreation activities. Financial support is more likely to be captured by a variety of donation mechanisms. Fundraising communications that promote purchase of conservation lands, or conservation on public lands, science, and education/outreach programs are more likely to attract donors than conservation on private lands. These findings provide important insights that can assist conservation groups in Canada and beyond in formulating public engagement strategies to enhance revenues from voluntary donations.
- OPEN ACCESSWhile community-based monitoring (CBM) can support meaningful participation of the public in environmental decision-making, it remains unclear if and how CBM can support western science approaches to biophysical studies within cumulative effects assessment (CEA). We scored 40 Canadian CBM projects on their ability to enhance CEA's western science approaches to environmental monitoring. We used multivariate analyses to determine if the highest-scoring projects shared characteristics that could inform the design of CBMs to support CEA. Cluster analysis and non-metric multi-dimensional scaling ordination revealed that highest-scoring projects were distinct from lower scoring projects, and the Similarity Percentages Routine identified characteristics that differentiated these projects. The highest-scoring projects involved non-profit organizations as bridging organizations that coordinated community participation and received funding and in-kind support from provincial/territorial government agencies. Participants in these projects collected measurements and samples using standardized protocols described in training manuals. Their data were publicly accessible in georeferenced databases and were used for baseline studies and resource management. There are existing CBM projects in Canada that thus appear well positioned to enhance western science approaches to CEA. Further study is required to identify how CBM projects can be designed to braid Indigenous and western science approaches to mutually enhance CEA methods.

Assisted migration is increasingly being considered as a potential climate change adaptation tactic even though it also comes with potential risk to ecosystems and society. When implementing conservation actions that involve risk, it is prudent to have policies and guidelines to ensure that such actions are conducted in ways that conform to regional standards and consider risks. Here, we report on a policy scan focused on assisted migration in the context of climate change adaptation originally as a protected areas tactic only, but then broadened to ecosystems in Canada beyond those boundaries. Policy scans are a useful strategy for understanding the evolving policy and regulatory landscape for a given topic and can guide the development of such policies in other jurisdictions. Our scan focused on Canada, where multi-scalar governance systems exist relevant to biodiversity and environmental management. Our comprehensive policy scan (involving scans of legislation, policies, and guidelines found online and through direct inquiries with government bodies) revealed major gaps in the assisted migration policy landscape with very few provincial/territorial or federal policies in Canada. A more rudimentary scan in the United States revealed a similar pattern. There was evidence that some jurisdictions anticipated need for such policies and even a few examples of very specific policies (e.g., seeds) that had already been developed, but there were not comprehensive policies or frameworks. Governments and other relevant bodies/organizations may wish to consider working collaboratively toward the development of robust, evidence-based policies for assisted migration given that we anticipate this conservation intervention becoming more popular as climate change impacts on ecosystems become more evident and dire. - OPEN ACCESSAlberta grizzly bears are classified as a threatened species in the province of Alberta as of 2010, with human-caused mortality and habitat loss a primary threat. The people who live, work, and recreate within bear habitat play a crucial role in their conservation. While the public is often enthusiastic about grizzly bears, and opportunistically report their observations to government staff, these reports are not systematic or rigorously collected and lack key information. As such, we developed GrizzTracker as a community science program. Following several years of successful deployment, we analyzed community scientist data and evaluated the efficacy of the program through an online user survey. We found that the GrizzTracker app was useful as a data collection and public engagement tool, yielding information for applied management, and that community scientists were generally satisfied. We provide considerations for future program development, including considerations for human, social, technological, and financial capital investment related to design, development, and implementation of data collection protocols, the importance of clearly communicating outcomes, and opportunities for educational outreach. While there is continued trepidation by traditionally trained scientists to develop or engage in community science programs, and some noted areas of improvement for our program specifically, we think that GrizzTracker offers a success story in community science.
- OPEN ACCESSAssessing cat local abundance provides information on where wandering cat numbers are highest and what habitats or factors are associated with wandering cats. A variety of stakeholders can lead this research and then use the findings to make scientifically informed decisions to guide the physical locations of cat management actions. Here, we document a framework that engages community members, uses minimal equipment (six trail cameras), and provides scientifically derived information for interested parties to inform, direct, or test the effectiveness of cat management practices. Using these methods in Gatineau, Quebec, Canada, we demonstrate how we estimated cat population size and cat local abundances across a variety of co-variates while accounting for non-perfect detection by using 55 trail camera sites and N-mixture models. Urban areas had three-fold higher local wandering cat abundances than parkland areas, and neighbourhoods below the median income had the highest local abundances of wandering cats. We estimated there are between 8905 and 48,419 (mean 21,298) wandering cats in Gatineau, with 18%–73% of those cats being unowned. These findings can be used to identify locations for future cat management. If estimates of cat abundance are repeated, they can assess the effectiveness of management actions.

In late 2020, a private volunteer group operating through a Facebook group approached Toronto and Region Conservation Authority (TRCA) with an interest in participating in the Citizen Science Nest Protection and Monitoring Volunteer Program. During the 2021 season, TRCA staff virtually trained volunteers in turtle nest detection, protection, and monitoring due to COVID-19 social constraints, and provided necessary supplies and equipment. In 2021 volunteers and staff detected 181 turtle nests and were able to protect 75 nests with simple predator-exclusion devices, while in 2022, 165 nests were detected, and 155 were protected. The volunteers also collected data, including nesting location, date, and species in addition to the number of successful hatchlings (2021 only). In 2021, the 75 protected nests yielded 81 Midland Painted Turtle and 665 Snapping Turtle hatchlings. Five Midland Painted Turtle’s eggs were also recovered from an injured turtle, and 44 Snapping Turtle eggs were recovered from a partially predated nest, transported to the Ontario Turtle Conservation Centre, incubated, hatched, and overwintered, and then released back into the local wetlands. The partnership with a local community group proved effective, and we would recommend this practice to other conservation organizations interested in turtle nest protection. - OPEN ACCESS

Poweshiek skipperling (Oarisma poweshiek Parker, 1870) populations have declined precipitously in the past few decades, and their global range is now restricted to two isolated regions, one of which is the managed Manitoba tall grass prairie in Canada. In this paper, we used a decade of survey data from 2010 to 2019 to understand how habitat features, management practices, and extreme weather impact Poweshiek skipperling abundance in Manitoba. The strongest predictor of abundance was the density of black-eyed Susans (Rudbeckia hirta L.), a primary nectar plant for adults. Poweshiek skipperling abundance also had a negative relationship with both the number of years since a burn occurred and the number of years since grazing occurred. Cumulative precipitation during their active period (May–June) had a negative relationship with skipperling abundance, whereas warm early springs and cool temperatures during the active period had positive relationships. These results suggest that management actions that maintain tall grass prairie habitat in an early successional stage (burning and grazing) and maintain important nectar sources benefit this population. In contrast, extreme weather events had varying effects on Poweshiek skipperling abundance. Results from this study inform ongoing management practices in the Manitoba tall grass prairie to support this endangered population. - OPEN ACCESSDespite the challenges posed by climate change and the biodiversity crisis, most academic research continues to stay within academia and the gaps between conservation science, policy, and practice remain intact. We need to improve the exchange of evidence between researchers and conservation practitioners and focus on solutions-oriented, interdisciplinary science and co-developed research. As we continue to break climate records and lose record numbers of species every year, now is the time for academics to think and act beyond their institutions.

A laboratory-based study was conducted to investigate the consumption and degradation of expanded polystyrene (EPS) by superworms (darkling beetle larvae, Zophobas morio; heterotypic synonym Zophobas atratus). Superworms fed on one of three diets (wheat bran control, EPS blocks, or EPS S-shaped chips) following a 60-second pretreatment with UV radiation or no UV radiation exposure. Loss-of-mass measurements were conducted every week for 4 weeks. Nutrients (nitrogen and phosphorus) and EPS degradation products in frass were determined as well as the superworm gut microbiome composition. The average loss of mass after 28 days was 34.7% for EPS blocks and 25.6% for S-shaped chips. Small quantities of nitrogen and phosphorus were found in the frass of superworms that fed on the EPS diet, but they were lower than those from wheat bran-fed superworms. Twenty-one EPS degradation products were identified in the frass of superworms on an EPS diet, including short-chain carboxylic acids, polyols, amino acids, metabolites of amino acids, and phosphoric acids. Pseudomonas aeruginosa (polystyrene degrader) and Stenotrophomonas sp. (nitrogen fixer and phosphorus solubilization promoter) were identified from the guts of superworms that fed on an EPS diet. Overall, superworms have the potential to deal with plastic waste degradation problems. - OPEN ACCESSIn recent years, increasing attention has been directed to “natural climate solutions” to mitigate climate change through the protection, restoration, and improved management of carbon-storing ecosystems. In practice, Indigenous Peoples have been implementing natural climate solutions for millennia through land stewardship. As Indigenous nations and communities in Canada reassert stewardship roles through Indigenous Guardians programs, the question arises: what possibilities emerge when natural climate solutions are driven by Guardians, guided by multifaceted community priorities and Indigenous knowledge? This paper responds to this question, drawing upon collaborative research with Wahkohtowin Development, a social enterprise based in Treaty 9 territory (Ontario, Canada), made up of Chapleau Cree First Nation, Missanabie Cree First Nation, and Brunswick House First Nation. We engaged youth Guardians in workshops that generated insights on the role of youth, cross-cultural collaboration, and holistic conceptualizations of climate action rooted in Indigenous ontologies (such as the Cree philosophy of wahkohtowin, embodying kinship and interconnectedness). Our analysis reveals that Indigenous Guardians are well positioned to advance natural climate solutions and to do so in an integrative manner that addresses intersecting challenges—with benefits for communities, ecosystems, climate action, and reconciliation.

The strengths of Indigenous Knowledges and need for reconciliation are increasingly recognized within conservation, leading to a rise in collaborative, cross-cultural research initiatives. As both a cultural keystone and important harvest species, moose are of value to both Indigenous and non-Indigenous Peoples, presenting an opportunity to pursue moose monitoring strategies that embrace the strengths of Indigenous and Western knowledges. While various frameworks provide theoretical direction on how to do so, few resources outline how to apply them in practice. Leaning on guidance of the Ethical Space framework, we explored the meaning and application of value-based approaches in the context of moose monitoring in central Ontario through semi-structured interviews with First Nation communities, the Ontario provincial crown government, and academic researchers. Collectively, 20 core values were identified to be important when bringing Indigenous and non-Indigenous partners together, coupled with a range of tangible actions necessary for fostering Ethical Space. Values and actions reflected three main themes: an emphasis on the long term, the importance of building and maintaining relationships, and the ability to evolve and adapt over time. Insights from this research provide tools and guidance for others interested in enacting Ethical Space in the context of cross-cultural wildlife monitoring and research. - OPEN ACCESSMarine protected areas (MPAs) are critical in safeguarding biodiversity and ecosystem functions under climate change. The long-term effectiveness of these static conservation measures will depend on how well they represent current and future ocean changes. Here, we use the Climate Risk Index for Biodiversity to assess the vulnerability representation of marine ecosystems within the Canadian marine conservation network (CMCN) under two divergent emissions scenarios. We found that MPAs best represent climate vulnerability in Atlantic Canada (85% representativity overall, and 93% in the Gulf of Saint Lawrence under low emissions), followed by the Pacific (78%) and Arctic (63%; lowest in the Eastern Arctic (41% under high emissions) regions). Notably, MPAs with lower climate vulnerability are proportionally overrepresented in the CMCN. Broad-scale geographic targets employed in the Scotian Shelf-Bay of Fundy network planning process achieve over 90% representativity of climate vulnerabilities, underscoring the importance of ensuring habitat representativity and geographic distribution in conservation planning to enhance climate resilience, even if not explicitly prioritized. Moving towards Canada’s target to protect 30% of its waters by 2030, prioritizing representativity and designation of MPAs in currently underrepresented climate-vulnerable regions may be crucial to enhancing the resilience of the CMCN amidst an ever-changing climate.
- OPEN ACCESSIn Quebec, the Act Respecting Threatened or Vulnerable species (ARTV), adopted in 1989, aims to safeguard Quebec's wild genetic diversity by protecting species at risk. However, since its implementation about 30 years ago, it has been repeatedly pointed out that the application of the Quebec legislative framework for the protection of wildlife species at risk was often slow and inadequate. The aim of this article is therefore to make a series of observations on the limits of current legislation and then propose nine urgent recommendations to improve the effectiveness of conservation efforts for species at risk in Quebec. Our recommendations aim to increase the efficiency and transparency of the designation process, reconsider compensation mechanisms for the loss of critical habitat, and harmonize species status between the federal and provincial levels. We hope that our article will pave the way for a constructive discussion leading to an improved protection of wildlife species in precarious situations and their persistence for future generations. The English version of this article is available in the Supplementary material file.
- OPEN ACCESSLarge amounts of waste paper are generated annually worldwide. Although some of it is recycled, up to 50% is landfilled or incinerated. The remanufacturing of waste paper to produce pencils is proposed as a novel, sustainable business solution. A sustainability analysis of this process was performed to quantify indexes of technical, environmental, economic, and social sustainability. Small-to-medium business models were evaluated, in which 15 000 pencils/shift/day can be produced from 135 kg of waste paper, with a maximum productivity of 64 800 pencils/day. Productivity, operating costs, power consumption, land footprint, machine delivery cost, and number of workers were used to analyze the technical feasibility. The cost-to-profit ratio, cost and profit per pencil, and daily profit were used to evaluate economic sustainability. The amounts of municipal solid waste and recovered paper waste, saved embodied energy, and prevented CO2 emissions were used to analyze environmental sustainability. The number of workers and labor costs were used to evaluate human development and social sustainability. The machines required for the remanufacturing line are considered sufficiently mature, remanufactured pencils are less expensive to produce than wooden pencils, and the proposed process minimizes the amount of waste paper sent to landfills and avoids the use of new wood for producing pencils, thereby satisfying technical, economic, and environmental sustainability, respectively. The final sustainability index of 0.9 is considered very high and sufficient for operating a profitable, sustainable business with a profit of 252–583 USD/day.
- OPEN ACCESSMany of Canada’s waterways are modified by the deepening and straightening of stream channels, converting them into agricultural drains to create arable land. While these agricultural drains support diverse aquatic communities and provide important habitat for species at risk, current policies allow for maintenance activities that threaten the survival and longevity of at-risk fish populations. Using three case studies from Ontario, we highlight current challenges to protecting aquatic species at risk in agricultural drains and potential conservation actions that can be taken to protect and restore aquatic species at risk and their habitat within those drains. Conservation actions may vary from ecological modeling to collaborative development of mitigation techniques, and restoration of naturalized habitat in anticipation of future alterations. We provide nine recommendations (including improved legislation, permitting, mitigation, and compliance) on how to better conserve and protect aquatic species at risk in agricultural drains in the future.

The impacts fishing communities face as a result of declining fisheries productivity and access may largely hinge on measurable attributes of their social resilience. Wild-origin Pacific salmon populations have been in a marked decline since the 1960s, resulting in progressively declining access for many commercial fisheries. More recent acute stressors have caused appreciable tribulation to commercial fishers in British Columbia, raising concern over their capacity to remain viable in the industry, and underscoring the need to examine the fishery under a social resilience framework. Here, we coupled an online survey instrument with in-depth interviews to assess commercial salmon fishers’ social resilience, socioeconomic characteristics, risk perceptions, trust in fishery management, and the relationships between these variables. Our results show that social resilience is low overall, with older, more experienced, and less diversified fishers being particularly vulnerable to declining salmon access. While 73% of fishers reported having plans to adapt to future declines in salmon access, 92% reported feeling that there are barriers impeding their adaptation, and 75% reported having no trust in fisheries management helping them adapt. Fishers’ social resilience was positively correlated with their trust in, and perceived trust from fisheries management. - OPEN ACCESSReintroduction is an important tool in the conservation and recovery of aquatic species at risk. However, components of the reintroduction process such as transportation have the potential to induce physiological stress and the extent to which preparatory techniques can mitigate this stress is poorly understood in small-bodied fishes. To address this concern, we studied the effect of transport on two fitness-related performance measures: maximum metabolic rate and thermal tolerance in redside dace (Clinostomus elongatus), an imperilled small-bodied stream fish native to eastern North America. Prior to transportation, we manipulated the body condition of redside dace over a 12-week period, by providing either low (1% of their total body mass) or high (2% of their total body mass) rations. The goal of this manipulation was to influence body condition, as higher body condition can enhance physiological performance. Subsequently, redside dace were transported for varying durations: 0, 3, and 6 h. Following transportation, we measured maximum metabolic rate (µmol/h) and thermal tolerance (CTmax, °C). Our results indicate that neither transport nor body condition had a significant effect on maximum metabolic rate or thermal tolerance (CTmax). These findings provide preliminary evidence that redside dace can physiologically tolerate transport based on the endpoints measured and this information may possibly be extended to other small-bodied fish, for which information is lacking.

In many regions, a tradeoff exists between draining wetlands to support the expansion of agricultural land, and conserving wetlands to maintain their valuable ecosystem services. Decisions about wetland drainage are often made without identifying the impacts on the services these systems provide. We address this gap through a novel assessment of impacts on ecosystem services via wetland drainage in the Canadian prairie landscape. Draining pothole wetlands has large impacts, but sensitivity varies among the indicators considered. Loss of water storage increased the magnitude of median annual flows, but absolute increases with drainage were higher for larger, less frequent events. Total phosphorus exports increased in concert with streamflow. Our analysis suggested disproportionate riparian habitat losses with the first 30% of wetland area drained. Dabbling ducks and wetland-associated bird abundances respond strongly to the loss of small wetland ponds; abundances were predicted to decrease by half with the loss of only 20%–40% of wetland area. This approach to evaluating changes to key wetland ecosystem services in a large region where wetland drainage is ongoing can be used with an economic valuation of the drainage impacts, which should be weighed against the benefits associated with agricultural expansion. - OPEN ACCESS

Plants make up more than one quarter of all species listed under Canada’s Species at Risk Act, but very few have improved in status over time. Ineffective legal protections, lack of public awareness, difficulties in prioritizing species, and a scarcity of research relevant to the recovery of plant species at risk are some of the many challenges facing effective plant conservation in Canada. We used an online survey to ask 243 people who work in plant conservation or who do research in plant ecology or evolution to assess the state of plant conservation in Canada and to identify the actions needed to improve it. Most respondents agreed that Canada is underperforming or merely average when it comes to conserving plants. Based on their responses, we outline a set of recommendations that could form the basis of a national strategy for plant conservation in Canada. These include greater advocacy for habitat protection, connecting researchers with funding opportunities, supporting graduate students working on research related to plant conservation, increasing public awareness of plants, collaborating with and respecting Indigenous knowledge holders, promoting collaboration between researchers and local conservation groups, and increasing capacity to assess the status of species that are potentially at risk. - OPEN ACCESS

It can be challenging for practitioners to determine reasonable response actions following an environmental spill because there are risks associated with the recovery process, acute constraints on time, and few case studies available from antecedent events. Here, we evaluate environmental risk using a screening level assessment (SLA) and describe risk management actions during the response phase of a train derailment that released 600 tonnes of fly ash into a headwater creek in Banff National Park, Canada. Trace metal concentrations and physico-chemical parameters from downstream of the derailment site were compared to Canadian environmental quality guidelines and upstream reference values. There was a 1–2.2-fold exceedance of sediment quality guidelines (As, Cd, and Se) as well as a 3.6–17.5-fold exceedance of water quality guidelines (Al, Cd, Fe, and turbidity) downstream of the train derailment. Despite uncertainty about site-specific toxicity when using a SLA, we did require the removal of the settled fly ash from the creek based on the multiple exceedances of guidelines, regulatory context, wilderness setting, and potential contribution to cumulative effects downstream. Case studies that evaluate risk and describe risk management actions help practitioners make consistent and efficient decisions during the response phase of a spill. - OPEN ACCESS

The movement ecology of Bull Trout (Salvelinus confluentus) in watersheds at the northern geographic range extent is not well understood. We implanted 54 Bull Trout with acoustic transmitters in the Prairie Creek watershed, Northwest Territories, Canada and tracked fish from July 2011 to October 2012 using 19 stationary hydrophones. Bull Trout movement patterns generally corresponded to two groups, as a result of individual variation within and across seasons. The first group exhibited seasonal variations in movement and habitat use, moving most (range 11.7–115.9 km) and occupying the largest home ranges in summer and autumn, while exhibiting little movement during winter and spring. The second group made negligible movements within seasons and resided in localized areas. Restricted movement in winter resulted in a severe range contraction. The average distance moved within a season was 11.5 km (range 0.3–64.9 km per fish). The unusually high prevalence of stationarity in this watershed suggest fish can complete all life processes (spawning, feeding, and rearing) in short reaches (<10 km) of Prairie Creek and tributaries. We encourage researchers to replicate our work in other northern watersheds to determine if the life history we describe represents a regional divergence from more southerly populations. - OPEN ACCESS

Canada’s provinces and territories govern species at risk across most of Canada, with the federal Species at Risk Act generally covering only aquatic species, migratory birds, and species living on federal land. More than a decade after a 2012 report by the environmental law charity Ecojustice on species at risk protection in Canada, we use the same criteria to evaluate the current state of provincial and territorial species at risk legislation, and we provide updates on changes in each jurisdiction since 2012. These criteria are as follows: whether at-risk species are being identified, whether these species are being protected, whether their habitat is being protected, and whether species recovery plans are being created and implemented. We find that there is considerable variation across jurisdictions, with shortcomings that result in inadequate protections for at-risk species, as well as strong components that should be adopted by all jurisdictions. We recommend seven key areas for improvement: dedicated and harmonized legislation, limited discretionary power, increased embrace of scientific and Indigenous knowledge, appropriate timelines for actions, reasonable exemptions to protections, habitat protection across land ownership types, and transparency throughout the process. We urge policymakers to address current shortcomings as they work toward meeting Canada’s biodiversity conservation commitments. - OPEN ACCESS

There is a global movement to implement a One Health approach across sectors to holistically address emerging issues that have implications for public, animal, and environmental health. The operationalization of a One Health model can support knowledge sharing and build an evidence base for designing research programs and decision-making tools to evaluate and mitigate intersectoral health challenges. In late 2021, the highly pathogenic avian influenza virus (HPAIV) H5N1 2.3.4.4b was detected in eastern Canada, and subsequently spread throughout the flyways of North America. Given the multiyear persistence of the current HPAIV in Europe and the continued detections in North America, Environment and Climate Change Canada and partners recognized the need to prioritize HPAIV-related information needs to inform future decision-making and management. In early 2023, we carried out an expert opinion exercise with partners from across One Health domains and expertise to prioritize information needs related to the conservation and management of migratory birds in Canada. The results informed on-the-ground programming for migratory bird activities in 2023 and onwards. The process illustrates how a One Health lens can be applied with a conservation focal point, using dedicated facilitation to synthesize expert opinions across groups with non-overlapping mandates. - OPEN ACCESS

The international collaboration network Food Systems Innovation to Nurture Equity and Resilience Globally (Food SINERGY) unites food system experts concerned with the confluence of environmental, geopolitical, economic, and public health stressors that weaken food systems and increase inequalities. In March 2023, Food SINERGY participants from universities, research institutes, food policy advocacy groups, Indigenous networks, farmers’ associations, consumer organizations, social enterprises, and non-governmental organizations from around the world met in Mont Orford, Québec, for a forum to revisit food system structures across local-to-global scales and to identify key junctures for transformation. This article summarizes the network's discussions in the context of the existing literature. Key knowledge contributions include the importance of diversification throughout the food system for cultivating resilience; the value of food sovereignty in promoting equity across scales; the reconciliation between food sovereignty and equitable trade; the need for consonance between policy environments at different scales to enable positive societal actions; the pioneering role of food system innovations that challenge conventional political and economic structures, with emphasis on agroecology; and the need for critical self-reflection around knowledge production and knowledge use to better serve equitable food systems. These discussion outcomes provide insights for actors seeking to transform food systems in support of equity and resilience. - OPEN ACCESS

Recreational fisheries involve an intimate connection between people, individual fish, and the environment. Recreational fishers and their health crucially depend on healthy fish and ecosystems. Similarly, fish and ecosystems can be impacted by the activities of people including recreational fishers. Thus, amplified by the global interest in recreational fishing, we posit that recreational fishing is particularly suited as an empirical system to explore a One Health perspective, with a goal of creating pathways to better manage such socio-ecological systems for the benefit of people, fish, and the environment. Although zoonoses are uncommon in fishes, fish can carry pathogens, biotoxins, or contaminants that are harmful to people. When captured and released, fish can experience stress and injuries that may promote pathogen development. Similarly, when humans contribute to environmental degradation, not only are fish impacted but so are the humans that depend on them for nutrition, livelihoods, culture, and well-being. Failure to embrace the One Health perspective for recreational fisheries has the potential to negatively impact the health of fish, fisheries, people, society, and the aquatic environment—especially important since these complex social–ecological systems are undergoing rapid change. - OPEN ACCESSSeeking to capitalize on a surge in global demand for critical minerals, the Canadian mining sector claims that regulatory processes like Environmental Assessment (EA) impede and delay mining’s economic benefits. This paper investigates whether regulation has delayed mining projects and how much economic benefit mines have delivered in British Columbia (BC), focusing the mines’ performance post-EA. We audit the 27 mines granted an EA certificate in BC since 1995 and projected to open by 2022, comparing each mine’s forecasted and actual timelines and economic benefits (production, employment, and taxes), and identifying publicly-stated reasons for any mine delays. Seven of the 27 mines opened on time: 13 remain non-operational, and of the 14 mines that have operated, seven were delayed. Regulation was cited as a factor in only three of the 20 delayed projects; economic factors like commodity prices were the most common cause of delay. Lack of data and transparency on economic benefits significantly constrained our benefit audit, but BC mines for which data are available are underperforming across production (−77%), employment (−82%), and tax revenue (−100%). These findings suggest economic underperformance and mine delays post-EA are common, with delays typically resulting from economic factors, not government regulations.
- OPEN ACCESSWith the influence of climate change on marine systems expanding, climate adaptation will be fundamental for the future of fisheries management. An exponential increase in Atlantic halibut Hippoglossus hippoglossus landings over the past decade has coincided with warming ocean temperatures. Here, we explore how historical changes in abundance have been linked to changing thermal habitat conditions and project trends with a warming climate under different emissions scenarios. From 1990 to 2018, available thermal habitat increased by 11.6 ± 7.35% and growing degree days have increased by 13.5 ± 7.86 °C·days across the region. With warming, the probability of occurrence is projected to increase up to 20.5% in Canada by 2085 under RCP 8.5 for Atlantic halibut. Our results suggest that shifting patterns of halibut distribution and abundance are linked to thermal conditions and that continued warming will likely continue to enhance habitat conditions, leading to increased abundance in the Canadian range. Collectively, these results illustrate the influence of shifting environmental conditions on population dynamics and emphasize the importance of adaptive management practices in a dynamic future climate.
- OPEN ACCESSMismatches between institutions and social–ecological systems (SESs) are one of the foremost challenges in natural resource management. However, while mismatches are often cited in the literature as a major challenge, empirical evidence of mismatches and their consequences is limited. This is particularly true for complex SESs, such as on the Pacific Coast of North America, where salmon drive interactions across multiple environments, jurisdictions, and scales. Here, I use the theoretical concept of fit to examine institutional alignment in a large-scale Pacific salmon SES, the Skeena River watershed in British Columbia, Canada. Utilizing Canadian federal environmental assessments as a proxy for colonial environmental governance institutions, I describe the common causes and consequences of mismatches between institutions and salmon SESs. This case study suggests that mismatches are threatening salmon sustainability and negatively affecting Indigenous People’s rights, livelihoods, and approaches to resource management and stewardship. I argue that improving social–ecological fit in salmon SESs will require new or revitalized forms of environmental governance that consciously fit the underlying social–ecological dynamics. While these findings are based on the Skeena River watershed, they may be generalizable to other salmon SESs in which mismatches between social and ecological processes and institutions exist.
- OPEN ACCESSClimate change is affecting the ocean, altering the biogeography of marine species. Yet marine protected area (MPA) planning still rarely incorporates projected species range shifts. We used the outputs of species distribution models fitted with biological and climate data as inputs to identify trends in occurrence for marine species in British Columbia (BC), Canada. We assessed and compared two ways of incorporating climate change projections into MPA planning. First, we overlaid 98 species with modelled distributions now and by the mid-21st century under two contrasting (“no mitigation” and “strong mitigation”) climate change scenarios with existing Provincial marine parks in BC, to ask which species could overlap with protected areas in the future. Second, we completed a spatial prioritization analysis using Marxan with the projected future species ranges as inputs, to ask where priority regions exist for the 98 marine species. We found that many BC marine parks will lose species in both climate scenarios that we analyzed, and that protecting 30% of important marine species will be challenging under the “no mitigation” climate change scenario. Challenges included the coarse resolution of the data and uncertainty in projecting species range shifts.

The braiding of Indigenous knowledge systems and Western-based sciences offers insights into ecology and has emerged as a way to help address complex environmental issues. We reviewed the publicly available ecological research involving the braiding of Indigenous knowledge systems and Western-based sciences to support collaborative work in the Alberta oil sands region of Canada. We conducted a systematic review, coding for 78 questions in six categories: (1) literature search and bibliographic information; (2) research themes; (3) study setting and design; (4) knowledge systems; (5) power relationships, colonization, and ethical considerations in research; and (6) benefits and challenges of braiding. We identified six articles that braided knowledge, with those articles focusing on environmental management and monitoring for impacts of industrial activity in northern Alberta. Researchers used a broad range of approaches to gather Indigenous knowledge and scientific data and identified multiple challenges (e.g., asymmetries of power, resource availability, and funding) to research. Our findings show that more support is needed to foster, promote, and disseminate interdisciplinary collaborative work involving braiding. Additional support is also required to address Indigenous community research needs related to the assessment of environmental impact and reclamation, as well as the understanding of ecological threats across the region. - OPEN ACCESSThis perspective essay examines the role of conservation law in contributing to biodiversity decline by exploring how current conservation laws exacerbate the challenges Canada faces. We contend that there are three intertwined foundation-setting functions of conservation law: they codify priorities and values, define and influence acceptable conservation behaviour, and drive the establishment of the institutions, programs, and governance arrangements of today’s conservation regime. We describe these functions and then assess whether conservation laws in Canada are adequately fulfilling the functions. We find that the federal conservation law regime is sub-optimal and likely incapable of halting and reversing the negative biodiversity trends. Based on this, we suggest a set of conservation legislative principles capable of catalyzing change and supporting the transition to a more sustainable conservation future.

The world has set ambitious goals to protect marine biodiversity and improve ocean health in the face of anthropogenic threats. Yet, the efficiency of spatial tools such as marine reserves to protect biodiversity is threatened as climate change shifts species distributions globally. Here, we investigate the ability of global marine reserves to protect fish biomass under future climate change scenarios. Moreover, we explore regional patterns and compare worlds with and without marine reserves. We rely on computer modeling to simulate an utopian world where all marine reserves thrive and ocean governance is effective. Results suggest that climate change will affect fish biomass in most marine reserves and their surrounding waters throughout the 21st century. The biomass change varies among regions, with tropical reserves losing biomass, temperate ones gaining, and polar reserves having mixed effects. Overall, a world with marine reserves will still be better off in terms of fish biomass than a world without marine reserves. Our study highlights the need to promote climate resilient conservation methods if we are to maintain and recover biodiversity in the ocean under a changing world. - OPEN ACCESS

Wilderness and national parks play a fundamental role in defining Canadian identity, yet Indigenous Peoples have historically been excluded from conservation decisions, resulting in systematic dispossession and oppression. In this article, we collaborate with Dene Tha'First Nation to discuss the recent paradigm shift towards Indigenous-led conservation and propose guiding principles to advance and assert the critical role of Indigenous Peoples in conservation. We begin with a brief history of Indigenous Peoples in conservation, followed by the concept of Indigenous protected and conserved areas (IPCAs). Our analyses show that IPCAs have gained momentum recently, driven by the Truth and Reconciliation Commission and Canada's commitment to global conservation goals. With one of the largest landmasses and Indigenous populations in the world, IPCAs in Canada have the potential to make immense contributions to environmental and cultural conservation rooted in an intrinsic relationship to the land. Despite this biocultural diversity, as of 2022, less than 1% of Canada's landmass is declared as Indigenous-led protected areas. However, more than 50 Indigenous communities across the country have currently received funding to establish IPCAs or to undertake early planning and engagement that could position Canada as a global leader in Indigenous-led conservation. As the Government of Canada aims to designate 25% of the territory as protected space by 2025 and 30% by 2030, embedding Indigenous rights, knowledge, and values in the national conservation strategy will be essential to simultaneously honoring the commitments to reconciliation and meeting the ambitious targets stipulated in the Kunming–Montreal Global Biodiversity Framework. - OPEN ACCESSDinerstein et al. present a spatially explicit global framework for protected areas needed to reverse catastrophic biodiversity losses and stabilize climate. The Province of Ontario (Canada) stands out in this “Global Safety Net (GSN)” as a critical jurisdiction for meeting those goals, because of both the large extent of roadless lands and high carbon storage in terrestrial ecosystems. Simultaneously, pressure is increasing to develop unmanaged lands in Ontario, particularly in the Far North, for resource extraction. Here, we extract data from the GSN to identify and calculate the areal extent of target regions present in Ontario and critically review the results in terms of accuracy and implications for conservation. We show that when region-specific data are incorporated, Ontario is even more significant than what is shown in the GSN, especially in terms of carbon stocks in forested and open peatlands. Additionally, the biodiversity metrics used in the GSN only partially capture opportunities for conservation in Ontario, and the officially recognized extent of Indigenous lands vastly underestimates the role of First Nations in conservation. Despite these limitations, our analyses indicate that Ontario plays an outsized role in terms of its potential to impact the trajectories both of biodiversity and climate globally.

With Inuit organizations leading the way, there is a growing opportunity for meaningful partnerships between Inuit and visiting researchers to create impactful research programs and policy initiatives that reflect Inuit priorities. Collaborative research methods, where Inuit and visiting researchers work together to meet community needs, offer a potential avenue for braiding knowledge systems, and therefore have become an increasingly popular way to conduct research in the Arctic. In this paper, we outline our use of the data analysis method known as the “Framework Method” during the Imappivut Knowledge Study, a participatory mapping project led by the Nunatsiavut Government. We reflect on both the method's applicability and its usefulness for future research conducted in collaboration between Inuit and non-Inuit researchers. We find that the Framework Method allowed us to work in an iterative and adaptive manner, resulting in comprehensive findings for marine spatial planning. The method also supported data sovereignty for the Nunatsiavut Government. The Framework Method can be used to allow Nunatsiavut greater control over the data internally and self-determining access to external researchers. - OPEN ACCESSSeasonal variation in seagrass growth and senescence affects the provision of ecosystem services and restoration efforts, requiring seasonal monitoring. Remotely piloted aircraft systems (RPAS) enable frequent high-resolution surveys at full-meadow scales. However, the reproducibility of RPAS surveys is challenged by varying environmental conditions, which are common in temperate estuarine systems. We surveyed three eelgrass (Zostera marina) meadows in Newfoundland, Canada, using an RPAS equipped with a three-color band (red, green, blue [RGB]) camera, to evaluate the seasonal reproducibility of RPAS surveys and assess the effects of flight altitude (30–115 m) on classification accuracy. Habitat percent cover was estimated using supervised image classification and compared to corresponding estimates from snorkel quadrat surveys. Our results revealed inconsistent misclassification due to environmental variability and low spectral separability between habitats. This rendered differentiating between model misclassification versus actual changes in seagrass cover infeasible. Conflicting estimates in seagrass and macroalgae percent cover compared to snorkel estimates could not be corrected by decreasing the RPAS altitude. Instead, higher altitude surveys may be worth the trade-off of lower image resolution to avoid environmental conditions shifting mid-survey. We conclude that RPAS surveys using RGB imagery alone may be insufficient to discriminate seasonal changes in estuarine subtidal vegetated habitats.

Much has been achieved by research into ecological restoration as a nature-based solution to the destruction of ecosystems, particularly in Canada. We conducted a national-level synthesis of Canadian restoration ecology research to understand strengths and gaps. This synthesis answers the following questions: Who is studying restoration? What ecosystem types are studied? Where is restoration studied? Which themes has restoration research focused on? Why is restoration happening? And how is restoration monitored and evaluated? We employed systematic searching for this review. Our results show that restoration research is conducted mainly by academics. Forest, peatland, grassland, and lake ecosystem types were the most commonly studied. There was a concentration of research in four provinces (Ontario, Quebec, Alberta, and British Columbia). Research into restoration has changed its thematic focus over time from reforestation to climate change. Legislation was the most common reason given for restoration. Restoration research frequently documented results of less than 5 years of monitoring and included one category of response variable (e.g., plant response but not animal response). Future research could investigate the outcomes of restoration prompted by legislation. At the dawn of the UN Decade on Ecosystem Restoration, this work demonstrates Canada's momentum and provides a model for synthesis in other countries. - OPEN ACCESSProtected areas (PAs) are a key component of most conservation strategies because they are thought to enhance biodiversity value relative to similar habitats in working landscapes. To examine whether PAs in Nova Scotia are functioning to enhance the biodiversity value of the landscapes in which they are embedded, we surveyed breeding bird communities in forested wetlands inside and outside of a large PA during 2018 and 2019. We found significantly higher species richness and diversity at sites in the working landscape relative to those inside the PA. Bird communities from different wetland types inside the PA were distinct from each other and those outside the PA, whereas bird communities at outside sites were homogenized and comprised of more early-successional species. There were numerous species of conservation concern at both inside and outside sites, indicating that both types of sites are playing important conservation roles. Abundances of these key species were driven by a combination of local (e.g., water table depth, herb, and shrub cover) and landscape scale factors (e.g., edge density and human disturbance). The higher abundance of long-distance migrants and insectivores at inside sites suggests PAs are providing critical additional support to key guilds that are in steep decline.
- OPEN ACCESSClimate change affects virtually all marine life and is increasingly a dominant concern for fisheries, reinforcing the need to incorporate climate variability and change when managing fish stocks. Canada is expected to experience widespread climate-driven impacts on its fisheries but does not yet have a clear adaptation strategy. Here, we provide an overview of a project we are developing, the Climate Adaptation Framework for Fisheries, to address this need and support climate adaptation in Canadian marine fisheries. The framework seeks to quantitatively and flexibly evaluate species, fishing infrastructure, and the management and operation of fisheries to assess climate vulnerability comprehensively and provide outputs that can support climate adaptation planning across different sectors, agencies, and stakeholders. This new framework should allow future climate scenarios to be evaluated and identify actionable climate vulnerabilities related to the management of fisheries, creating a systematic approach to supporting climate adaptation in Canada’s fisheries.
- OPEN ACCESSMarine Protected Areas (MPAs) are conservation tools that promote biodiversity by regulating human impacts. However, because MPAs are fixed in space and, by design, difficult to change, climate change may challenge their long-term effectiveness. It is therefore imperative to consider anticipated ecological changes in their design. We predict the time of emergence (ToE: year when temperatures will exceed a species’ tolerance) of 30 fish and invertebrate species in the Scotian Shelf-Bay of Fundy draft network of conservation areas based on climate projections under two contrasting emission scenarios (RCP 2.6 and RCP 8.5). We demonstrate a strong Southwest-to-Northeast gradient of change under both scenarios. Cold water-associated species had earlier ToEs, particularly in southwesterly areas. Under low emissions, 20.0% of habitat and 12.6% of species emerged from the network as a whole by 2100. Under high emissions, 51% of habitat and 42% of species emerged. These impacts are expected within the next 30–50 years in some southwestern areas. The magnitude and velocity of change will be tempered by reduced emissions. Our identification of high- and low-risk areas for species of direct and indirect conservation interest can support decisions regarding site and network design (and designation scheduling), promoting climate resilience.
- OPEN ACCESSInvertebrate pollinators are in trouble: particularly documented are declines among bees and butterflies. Interacting stressors include pesticides, pathogens, habitat loss, nonnative species, and climate change. Many governments have strategies to reduce negative pressures on pollinators, but Canada does not despite widespread public interest in pollinator health. This study serves as a needs assessment for science-based policy solutions for wild pollinator conservation in Canada. We designed a Policy Delphi survey technique to identify solutions that experts deem both desirable and feasible. Our secondary aim was to identify research priorities that would inform the implementation of these solutions. Sixty % of the 83 unique solutions were supported and feasible at a high consensus level (10% were “strongly” supported and “definitely” feasible). General themes included improving the Canadian government's approach in assessing pesticide risk to pollinators, curbing pathogen spillover/spillback between managed and wild pollinators, and reducing the reliance of Canadian agricultural systems on pesticides, among others. We discuss solutions in reference to pollinator conservation policies recommended by the broader scientific community and identify policy levers within the context of Canada's highly decentralized approach to biodiversity conservation/management and a political economy that uses high numbers of managed, mostly nonnative bees for pollination services.
- OPEN ACCESSThe creation and deployment of plastic structures made out of pipes and panels in freshwater ecosystems to enhance fish habitat or restore freshwater systems have become popularized in some regions. Here, we outline concerns with these activities, examine the associated evidence base for using plastic materials for restoration, and provide some suggestions for a path forward. The evidence base supporting the use of plastic structures in freshwater systems is limited in terms of ecological benefit and assurances that the use of plastics does not contribute to pollution via plastic degradation or leaching. Rarely was a cradle-to-grave approach (i.e. the full life cycle of restoration as well as the full suite of environmental consequences arising from plastic creation to disposal) considered nor were decommissioning plans required for deployment of plastic habitats. We suggest that there is a need to embrace natural materials when engaging in habitat restoration and provide more opportunities for relevant actors to have a voice regarding the types of materials used. It is clear that restoration of freshwater ecosystems is critically important, but those efforts need to be guided by science and not result in potential long-term harm. We conclude that based on the current evidence base, the use of plastic for habitat enhancement or restoration in freshwater systems is nothing short of littering.
- OPEN ACCESSDespite some progress, successful co-management in Canada has remained the exception rather than the rule, and especially so in jurisdictions not covered by a comprehensive land claims agreement. As such, our aim in this perspective is to identify and describe some of the primary factors that may impede more rapid progress toward successful co-management and to explore why they persist, with particular attention to fisheries and marine contexts. Specifically, we outline several institutional conditions that are likely to impede broader adoption of co-management approaches in Canada, including (1) antiquated and incomplete legislative arrangements; (2) a co-management policy vacuum that has not grappled with emerging expectations for co-governance; (3) relative absence of the knowledge co-production systems needed to create the precursors for successful co-management initiatives; and (4) financial and human resource capacity limitations. Such conditions must also be situated in a dynamic context that includes the United Nations Declaration of the Rights of Indigenous Peoples, ongoing reconciliation processes, and shifts in the ownership and use of fisheries and other marine resources. We offer, finally, some suggestions to augment co-management efforts and ultimately achieve its promise.

Wildlife conservation is informed by detailed understanding of species demographics, habitat use, and interactions with environmental drivers. Challenges to collecting this information, particularly in remote places and on widely ranging species, can contribute to data deficiencies that detract from conservation status assessment and the effectiveness of management actions. Polar bears in James Bay face rapidly changing environmental conditions at the southern edge of their global range, but studying their ecology has been limited by community concerns about the methods typically used in polar bear research. Using a community-led and non-invasive approach, we deployed hair snare and camera trap sampling stations across 400 km of the Eeyou Marine Region in eastern James Bay. Stations collected >100 hair samples and thousands of photographs in one eight-week period that allowed for a novel investigation of this population’s distribution and body condition during the ice-free season. Polar bears were in average to above average body condition, and model selection of detections at stations revealed distance to mainland as a significant predictor of polar bear presence. Given its high potential, we suggest community-based monitoring using this method become a standard protocol to expand the scope and local leadership of polar bear research across the North. - OPEN ACCESSThe impact of the southern Gulf of St. Lawrence American lobster (Homarus americanus) fishery on species bycatch is currently unknown. The composition of the incidental catch, both nonharvestable lobster (by fisheries regulations) and nonlobster species, was systematically collected over the 2015 spring and summer fishing seasons. A total of 51 948 (7147 were nonlobster taxa) individual organisms weighing 13 987.60 kg (1223.91 kg of nonlobster taxa) were captured as bycatch during 73 fishing trips. By weight per trip, the most common lobster bycatch were undersized male and females, and the highest nonlobster species catch were Atlantic rock crab (Cancer irroratus). A semiquantitative assessment of injury and vitality was applied to bycatch as a proxy for discard mortality. The majority of the individuals assessed for visible injury were deemed uninjured (98% both fish and invertebrates); however, postrelease mortality was not measured. A smaller study in 2019 corroborated the 2015 catches and supported current assumptions that the passive gear type, the low diversity of bycatch, and the rapid hand-sorting of the trap minimize the impact of the lobster fishery on incidentally captured taxa. Further scientific monitoring is recommended to better account for all sources of mortality in stock assessments and rebuilding plans.
- OPEN ACCESSInvasive species are a leading cause of biodiversity loss and species extinctions across ecosystems on a global scale. The historical and ongoing focus on single-species management of invasive species and species at risk contributes to inefficiencies in management strategies that present an obstacle to achieving desired outcomes. A holistic approach that consolidates and maps linkages between the broader collective of invasive species and species at risk in an area provides a more appropriate entry point for issue-based, rather than species-based, management planning. We present a case study of this approach from British Columbia, Canada, which synthesized the identity, mechanisms of impact, mechanisms of spread, and magnitude of impacts across 782 unique pairs of invasive species and federally listed species at risk, based on a literature review of species at risk documentation. The resulting dataset was used to summarize the nature of interactions across species pairs and taxonomic groups to help guide the development of invasive species response strategies that make the best use of limited management resources. As species invasions and extinctions become increasingly interconnected, holistic approaches rooted in cumulative effects assessment and ecosystem-based management can provide a stronger foundation for reducing or mitigating this growing threat.
- OPEN ACCESSWith growing attention to the ethical and equity implications of Western-based approaches to research, the urgency of decolonizing research has emerged as a critical topic across academic disciplines, including the field of sustainability. The complexity and messiness of this endeavour, however, may translate into uncertainty among researchers about how and where to start. This is partly due to a lack of guidance, training, and accountability mechanisms through Western academic institutions. In this paper, we advance a three-step process that systematically guides critical reflection toward respectful engagement of local and Indigenous communities, as well as other marginalized groups, by drawing on the literature and on learnings from a recent graduate student-led initiative. The process we develop aims to provide a pragmatic starting point for decolonizing research and a counterpoint to conventional modes of research. Such a process will not only foster accountability, respect, and reciprocity but also movement toward locally relevant, context-appropriate, and action-oriented research outcomes. Our three-step process also challenges Western-based and extractive research practices and seeks to facilitate a shift in mindset about the purpose of research and how to approach it.

Can fisheries be “regenerative”? Adapting agroecological concepts for fisheries and the blue economy
Regenerative design, in which agricultural practices are organized to work with nutrient cycles and successional processes, is increasingly being explored in food systems research and practice. In this commentary, I explore whether regenerative design concepts can be adapted to marine contexts, given increased global interest in the potential of marine ecosystems to support sustainable development, i.e., the blue economy. There are numerous fundamental ecological differences between terrestrial and marine ecologies that make it difficult to directly translate regenerative farming's focus on managing the nutrient cycle. However, building on a framework for regenerative food systems that focuses on how production activities are organized rather than the specific practices and technologies in use, I find multiple useful parallels to familiar patterns in the fisheries literature, specifically, fishing down the food web, poverty traps, and portfolio-based fishing. I conclude with a discussion of directions for research on regenerative fisheries and concerns regarding the potential for greenwashing under the banner of a regenerative blue economy. - OPEN ACCESS

Climate change is altering marine ecosystems across the globe and is projected to do so for centuries to come. Marine conservation agencies can use short- and long-term projections of species-specific or ecosystem-level climate responses to inform marine conservation planning. Yet, integration of climate change adaptation, mitigation, and resilience into marine conservation planning is limited. We analysed future trajectories of climate change impacts on total consumer biomass and six key physical and biogeochemical drivers across the Northwest Atlantic Ocean to evaluate the consequences for Marine Protected Areas (MPAs) and Other Effective area-based Conservation Measures (OECMs) in Atlantic Canada. We identified climate change hotspots and refugia, where the environmental drivers are projected to change most or remain close to their current state, respectively, by mid- and end-century. We used standardized outputs from the Fisheries and Marine Ecosystem Model Intercomparison Project and the 6th Coupled Model Intercomparison Project. Our analysis revealed that, currently, no existing marine conservation areas in Atlantic Canada overlap with identified climate refugia. Most (75%) established MPAs and more than one-third (39%) of the established OECMs lie within cumulative climate hotspots. Our results provide important long-term context for adaptation and future-proofing spatial marine conservation planning in Canada and the Northwest Atlantic region. - OPEN ACCESSAnthropogenic pressures, including urban and agricultural expansion, can negatively influence a lake's capacity to provide aquatic ecosystem services (ES). However, identifying lakes most at risk of losing their ES (i.e., higher vulnerability) requires integrating information on lake ecological state, global change threats, and ES use. Here, we provide a social–ecological framework that combines these features within a regional context by evaluating the ecological state of 659 lakes across Canada. Using the deviation of impacted lakes from reference ones, we identified much higher total nitrogen and chloride concentrations as the main indicators of an altered lake ecological state in all regions identified. Lake ecological state was mapped using an additive colour model along with regional scores of threat levels and recreational ES use. Urban and agriculturally developed areas were linked to higher lake vulnerability and ES loss. Lakes in Southern Ontario were most concerning, being highly altered, under threat, and heavily used. Lakes near coastal urban centers were altered and used, but less threatened, whereas those in the Prairies were altered and threatened, but less used. Our novel framework provides the first social–ecological geography of Canadian lakes, and is a promising tool to assess lake state and vulnerability at scales relevant for management.

- OPEN ACCESSExpanding and creating protected area networks has become a central pillar of global conservation planning. In the management and design of protected area networks, we must consider not only the positive aspects of landscape connectivity but also how that connectivity may facilitate the spread of invasive species, a challenge that has become known as the connectivity conundrum. Here, we review key considerations for landscape connectivity planning for protected area networks, focusing on interactions between network connectivity and the management of invasive species. We propose an integrative adaptive management framework for protected area network planning with five main elements, including monitoring, budgeting considerations, risk assessment, inter-organizational coordination, and local engagement. Protected area planners can address the dynamic aspects of the connectivity conundrum through collaborative and integrative adaptive management planning.

Traditional food systems based on harvest from the local environment are fundamental to the well-being of many communities, but their security is challenged by rapid socio-ecological change. We synthesized literature and data describing how a fundamental form of biodiversity, animal body size, contributes to the security of traditional food systems through relationships with species availability, accessibility, adequacy, and use. We found larger vertebrate species were more available, accessible, and used on a per kilogram basis, particularly for mammals. Conversely, larger species were no more or less adequate from a combined nutritional, health, and cultural perspective. Larger species represented more biomass, and this biomass required less time to harvest, with greater but more variable mean caloric returns over time. Smaller species provided more consistent caloric returns and were harvested during documented shortages of prey. This reliance on species with a range of body sizes is consistent with optimal foraging theory and the evolutionary value of flexibility, and highlights the importance of a biodiverse pool of species for traditional food security in times of change. Our synthesis of published literature and data highlights the many socio-ecological correlates of species size and how these relate to the security of traditional food systems. - OPEN ACCESS

The protection and promotion of healthy wildlife populations is emerging as a shared goal among stakeholders in the face of unprecedented environmental threats. Accordingly, there are growing demands for the generation of actionable wildlife health information. Wildlife health surveillance is a connected system of knowledge that generates data on a range of factors that influence health. Canada recently approved the Pan-Canadian Approach to Wildlife Health that describes challenges facing wildlife health programs and provides a path forward for modernizing our approach. This scoping review was undertaken to describe the range of peer-reviewed Canadian wildlife health surveillance literature within the context of the challenges facing wildlife health programs and to provide a quantitative synthesis of evidence to establish baselines, identify gaps, and inform areas for growth. This review describes patterns related to species, location, authorship/funding, objectives, and methodology. Five areas are identified that have the potential to propel the field of wildlife health: representativeness, expanded/diversified collaboration, community engagement, harmonization, and a shift to a solutions-focused and One Health mindset. This scoping review provides a synopsis of 10 years of Canadian wildlife health surveillance, challenges us to envision the future of successful wildlife health surveillance, and provides a benchmark from which we can measure change. - OPEN ACCESSThe degree to which human actions affect marine fisheries has been a fundamental question shaping people’s relationship with the sea. Today, divergences in stakeholder views about the impacts of human activities such as fishing, climate change, pollution, and resource management can hinder effective co-management and adaptation. Here, we used surveys to construct mental models of the Maine lobster fishery, identifying divergent views held by two key stakeholder groups: lobster fishers and marine scientists. The two groups were differentiated by their perceptions of the relative impact of pollution, water temperature, and fishing. Notably, many fishers perceive the process of fishing to have a positive effect on fisheries through the input of bait. Scientists exhibited a statistically significantly stronger concern for climate change and identified CO2 as one of the dominant pollutants in the Gulf of Maine. However, fishers and scientists agreed that management has a positive impact, which appeared to be a change over the past two decades, possibly due to increased collaboration between the two groups. This work contributes to the goal of decreasing the distance between stakeholder perspectives in the context of a co-managed fishery as well as understanding broader perceptions of impacts of human activities on marine ecosystems.
- OPEN ACCESSNatural resources in northern regions are often data-limited because they are difficult and expensive to access. Indigenous ecological knowledge (IEK) can provide information similar to, different from, or complementary to Western scientific data (WSD). We evaluated the general hypothesis that congruence in outcomes of IEK and WSD for population monitoring parameters is determined by temporal and spatial scale of the knowledge type. Parameters included population structure, degree of philopatry, morphological variation (and conservation status for one species), and genomics was a key Western scientific method. We evaluated this hypothesis in three subsistence and recreational fisheries (walleye, lake trout, and northern pike) in Mistassini Lake, Quebec, Canada. Concordance of outcomes was varied. IEK provided richer information on the biology, distribution, and morphological variation observable with the eyes. However, IEK cannot “see” into the genome, and WSD identified population structure and history more precisely than IEK. Both knowledge types could “see” change in populations, and the nature of what was seen both converged and was complementary. Determining when IEK and WSD are complementary or reach common conclusions may allow Indigenous communities to use both together, or one knowledge type over another when either is more desired, appropriate, or time- or cost-efficient to adopt.

American Eel (Anguilla rostrata) were used as a case study to assess whether Ontario’s Endangered Species Act proponent-driven regulatory approach resulted in successful imperilled species management outcomes. American Eel observation databases and proponent-prepared mitigation plans and monitoring data were used to assess whether: (i) facilities within the distribution range were registered, (ii) effects monitoring protocols were adequate to evaluate adverse effects of facilities, (iii) proponents implemented mitigation actions that followed best management practices (BMPs), and (iv) effectiveness monitoring designs were adequate to evaluate effectiveness of mitigation actions. Less than half of the facilities (8 of 17) within the extant species range were registered. Few eels were observed at each facility, precluding proponents from effectively evaluating the facilities’ effects. Mitigation actions following BMPs were only implemented for eel out-migration at three facilities. Half of the registered facilities implemented effectiveness monitoring, but experimental designs did not follow best practices and standards. To improve this proponent-driven approach, regulators could reduce ambiguity in regulation language and provide clearer, quantitative requirements for facility registration, effects monitoring, mitigation actions, and effectiveness monitoring. Proponents could improve monitoring efforts to establish species occurrence and generate baseline data to measure facility effects and mitigation action effectiveness. - OPEN ACCESSEfforts are underway in Canada to set aside terrestrial lands for conservation, thereby protecting them from anthropogenic pressures. Here we produce the first Canadian human footprint map by combining 12 different anthropogenic pressures and identifying intact and modified lands and ecosystems across the country. Our results showed strong spatial variation in pressures across the country, with just 18% of Canada experiencing measurable human pressure. However, some ecosystems are experiencing very high pressure, such as the Great Lakes Plains and Prairies national ecological areas that have over 75% and 56% of their areas, respectively, with a high human footprint. In contrast, the Arctic and Northern Mountains have less than 0.02% and 0.2%, respectively, of their extent under high human footprint. A validation of the final map, using random statistical sampling, resulted in a Cohen Kappa statistic of 0.91, signifying an “almost perfect” agreement between the human footprint and the validation data set. By increasing the number and accuracy of mapped pressures, our map demonstrates much more widespread pressures in Canada than were indicated by previous global mapping efforts, demonstrating the value in specific national data applications. Ecological areas with immense anthropogenic pressure highlight challenges that may arise when planning for ecologically representative protected areas.

- OPEN ACCESSThis article explores the “wholistic” as a central concept of “the good life” as expressed by the Bnkis, Tayal Indigenous Elders, who participated in the Day Club, Tayal territory of Northern Taiwan. In particular, we analyze the stories of care experienced by the Bnkis from the standpoint of wholistic relationships. The stories were recorded primarily between 2015 and 2018. In this analysis we used a critical qualitative design approach, privileging Tayal epistemology and informed by Tayal hermeneutics. Our results show that the concept of well-being for the Bnkis is closely linked to their relationships with people and with the land and spirituality. Through these relationships, the continuation of Gaga—Tayal law and cosmology—has been adapted organically over time. We argue that Gaga is central to Tayal Elder/Bnkis care and essential to Bnkis’ well-being. We propose that the concept of wholistic relationships embedded in the Tayal law of Gaga is vital in developing an elderly care system that is genuinely culturally relevant in the long run. This research demonstrates how the wholistic concept can improve human health and well-being, and ultimately provides an implication to sustainable development.
- OPEN ACCESSIn response to colonial research paradigms that have subjugated Indigenous Peoples, knowledges, lands, and waters, Indigenous research methodologies have emerged to center Indigenous visions and voices in research practice. Here, we employ such methodologies to improve collective understanding of the state and future of wild Pacific salmon (Oncorhynchus spp.) and fish–people–place relationships across British Columbia’s three largest salmon-producing rivers: the Fraser, Skeena, and Nass. Through partnerships with 18 communities of “Salmon People” and semi-structured interviews with 48 knowledge holders (i.e., Elders), we learned that, on average, Elders spent more than half of a century actively engaged in salmon fishing and processing. Modern salmon catches are reported to be approximately one-sixth of what they were estimated to be five to seven decades ago, and the top five threats to salmon identified by Elders included (i) aquaculture, (ii) climate change, (iii) contaminants, (iv) industrial development, and (v) infectious diseases. Threat priorities varied regionally, reflecting distinct lived experiences and regional variation in the prevalence and impact of different threats. Elders perceived threats to salmon equally as threats to aquatic health and human well-being, with evidence that the relationships between people and water, and salmon and people, are being profoundly transformed.

Indigenous Peoples’ lives, cultures, and values are defined largely by their long-term relationships with the lands, waters, and lifeforms of their territories. Their stories, names, ceremonies, and connections with the plants and animals on which they have depended over countless generations are cornerstones of their knowledge systems, systems of governance and decision-making, traditions of intergenerational knowledge transmission, and values and responsibilities associated with natural and human domains alike. For First Nations of North America’s Northwest Coast, as for many other Indigenous Peoples, the arrival of European newcomers disrupted both the natural world and associated cultural practices in interconnected ways. The industrial exploitation of lands and resources had wide-ranging effects: traditional land and resource appropriation; impacts on culturally significant habitats by industrial-scale fishing, logging, and mining; and discrimination and marginalization contributing to resource alienation. This paper documents some experiences of Kwakwaka’wakw and other Coastal First Nations in coping with the cultural effects of environmental loss. It highlights their concern for the ecological integrity of lands and waters formerly under their stewardship but reshaped by non-Native extractive economies, and describes how these losses have affected the cultural, social, and physical health of Kwakwaka’wakw peoples up to the present time. - OPEN ACCESSForested vernal pools serve an integral role in the recruitment of amphibians in glaciated northeastern North America. In south-central Ontario, vernal pools exist in relatively unimpacted forest networks, but the amphibian communities face uncertain challenges from anthropogenic-induced climate change. We surveyed amphibian larvae and collected measurements of habitat characteristics from vernal pools to collect baseline information on amphibian community structure and species–habitat relationships. Amphibian communities were influenced by hydroperiod length and canopy openness, and the relative abundances of early breeding amphibians were affected by changes in the structure of vegetation communities within pools. Our study suggests that, even across moderate ranges of breeding habitat characteristics, the structure of amphibian communities is dynamic. With anthropogenic-induced climate change leading to more drought-prone summers, the conservation of intact forests that support diverse wetland assemblages will be a necessary component of future legislation.

In British Columbia (BC), Canada, there is increased attention on mines and their impacts on water resources. In BC, many proposed mines undergo provincial environmental assessment (EA), which predicts a mine’s risks and involves government oversight and public engagement. After approval, mines can apply for amendments that alter the project’s undertakings, including in ways that may harm water resources. We examined all amendment documents for mines undergoing provincial EA in BC from 2002 to 2020. Of the 23 approved mines, 15 (65%) requested a total of 49 amendments, of which 98% were approved. Most mines applied for their first amendment within 3 years of approval. We deemed 20 of the approved amendments (associated with 10 projects) likely to have negative impacts on water resources, including changes to effluent discharge, increased volume of water extraction, or degradation of fish habitat. Amendment applications and approval documents lacked specific, quantitative information to reinforce claims or decisions. We present the first known summary of EA amendments in any jurisdiction. Given that most mines in BC receive amendments, and many are related to water, we express concern that amendment processes increase risk to water resources without meeting standards of evidence and public scrutiny required by the regular EA process. - OPEN ACCESS

Given its extensive volume and reach, social media has the potential to widely spread conservation messaging and be a powerful tool to mobilize social change for conserving biodiversity. We synthesized gray and primary academic literature to investigate the effects of social media on wildlife conservation, revealing several overarching benefits and risks. We found that social media can increase pro-conservation behaviours among the public, increase conservation funding, and incite policy changes. Conversely, social media can contribute to species exploitation and illegal trade, cause unprecedented increases in tourism in protected areas, and perpetuate anti-conservation behaviours via misinformation. In most cases, we found that content sharing on social media did not result in a detectable impact on conservation; in this paper, however, we focus on providing examples where conservation impact was achieved. We relate these positive and negative outcomes of social media to psychological phenomena that may influence conservation efforts and discuss limitations of our findings. We conclude with recommendations of best practices to social media administrators, public social media users, nongovernmental organizations, and governing agencies to minimize conservation risks while maximizing beneficial outcomes. By improving messaging, policing online misconduct, and providing guidance for action, social media can help achieve wildlife conservation goals. - OPEN ACCESSImpact assessment (IA) processes rely on the ability of assessment boards and their assessors to gather, synthesize, and interpret knowledge from a variety of sources, making IA a knowledge-based activity. IA boards in northern Canada operate in a context that prioritizes pluralism, where Indigenous knowledge is a key element of decision-making and the ability of practitioners to interact with knowledge—research capacity—affects process effectiveness, credibility, and legitimacy. Drawing on common principles from existing research capacity frameworks, we identify the dimensions of capacity most relevant to more fully realizing inclusive impact assessment processes. We then examine the Yukon Environmental and Socio-Economic Assessment Board (YESAB) as a specialized environmental governance organization with assessors whose research capacity directly impacts process outcomes. Results show that while common dimensions across knowledge-based disciplines, such as sufficient resources (e.g., financial support), are often addressed in the YESAB context, others unique to IA, like contextual understanding, require further examination. The interaction between individual and organizational research capacity is a complex balance between investing in individuals and investing in organizational supports. The proposed framework facilitates multi-scalar supports for individual assessors and assessment bodies alike to navigate balancing technical and value-driven knowledge in assessments.
- OPEN ACCESSThis research examines the potential challenges and opportunities for Mi’kmaq, the Indigenous peoples who have inhabited modern-day Nova Scotia and other areas of Eastern Canada for millennia, to play a greater role in marine protected area (MPA) governance in Canada. Given Canada’s marine conservation objectives of 30% by 2030, there is a growing need for decisions affecting the establishment of MPAs to respect Indigenous rights, values, and knowledge. Using the Eastern Shore Islands (ESI) in Nova Scotia, Canada, an area of interest for MPA establishment, as a case study, we conducted 17 semi-structured interviews with both Mi’kmaq and non-Mi’kmaq participants involved in the ESI consultation processes. We used content analysis to identify key themes that respondents perceived to be affecting Mi’kmaq involvement in the federal MPA governance processes. Barriers to overcome included those deemed to be systemic within the current decision-making processes; limited understanding of Mi’kmaq culture, governance, and rights; limited clarity of Mi’kmaq rights, particularly those resulting in fisheries conflicts; and limited capacity. Opportunities highlighted the importance of meaningful consultation and understanding of Indigenous worldviews as well as the need for alternative approaches to state-led/top-down governance to improve Mi’kmaq participation in MPA governance in Atlantic Canada.
- OPEN ACCESSCumulative human impact analysis is a promising management tool to estimate the impacts of stressors on ecosystems caused by multiple human activities. However, connecting cumulative impact scores to actual ecosystem change at appropriate spatial scales remains challenging. Here, we calculated cumulative effects (CE) scores for 187 seagrass beds in Atlantic Canada that accounts for both bay-scale and local-scale anthropogenic activities. We then developed a CE threshold to evaluate where degradation of seagrass beds from multiple human activities is more likely. Overall, the CE score was the best predictor of human impacts for seagrass beds. Locations with high watershed land alteration and nitrogen loading had the highest CE scores; however, we also identified seagrass beds with high CE scores in regions characterized by generally low levels of human activities. Forty-nine seagrass beds exceeded the CE threshold and, of these, 86% had CE scores that were influenced by three or more stressors that cumulatively amounted to a large score. This CE threshold approach can provide a simplified metric to identify areas where management of cumulative effects should be prioritized and further highlights the need to consider multiple human activities when assessing anthropogenic impacts to coastal habitats.

A seminal report by Peter H. Pearse (1988; Rising to the Challenge: A New Policy for Canada’s Freshwater Fisheries, Canadian Wildlife Federation, Ottawa) outlined 62 policy recommendations focused on the management of Canada’s inland fisheries. Over three decades later, freshwater ecosystems and inland fisheries in Canada are still facing similar challenges with many emerging ones that could not have been foreseen. Here, we reflect on the contemporary relevance of the Pearse Report and propose recommendations that policy makers should consider. Broadly, our recommendations are: (1) manage fishes, fisheries, and habitat using a holistic co-management framework, with clearly defined fishery jurisdictions and partnerships with Indigenous governments; (2) engage in transparent, inclusive, and agile research to support decision-making; (3) facilitate knowledge co-production, involving interdisciplinary projects with diverse groups of actors and sectors including Indigenous Peoples, anglers, policy makers, scientists/researchers, governments, and the public; (4) embrace technological advances to support freshwater fisheries stock assessment and management; and (5) align policy and management activities in Canada with global initiatives related to increasing the sustainability of inland fisheries. We advocate for an updated comprehensive report such as the Pearse Report to ensure that we embrace robust, inclusive, and sustainable management strategies and policies for Canada’s inland fisheries for the next 30 years. It is time to again rise to the challenge. - OPEN ACCESS

Despite the ecological importance of fungi, we still know little about their diversity in Canada. One of the largest hurdles to implementing fungal conservation initiatives is the lack of fungal distribution data. As anthropogenic impacts accelerate the speed of environmental change, it is imperative that we fill this major information gap, critical for fungal protection. To gain insight on the conservation status of Canadian macrofungi, we took advantage of the large and growing body of fungal biodiversity data from government research (Wild Species 2020), citizen science, trained independent mycologists, university, and museum biodiversity research. The majority of macrofungi are data deficient; we do not know their geographic distribution or habitat requirements, occurrence, or abundance in Canada. For mushrooms that fruit only a few days of the year and are often difficult to positively identify, there is a lot of work to overcome the uncertainty of distinguishing under-sampling from rarity. Our work stresses the importance of building a strong network of professional and amateur mycologists to develop resources, disseminate information to make educated decisions, and advance conservation actions. We found that several fungi can be prioritized; we present a short list for consideration for formal conservation assessment. - OPEN ACCESS

The abundance, distribution, and size of marine species are linked to temperature and nutrient regimes and are profoundly affected by humans through exploitation and climate change. Yet little is known about long-term historical links between ocean environmental changes and resource abundance to provide context for current and potential future trends and inform conservation and management. We synthesize >4000 years of climate and marine ecosystem dynamics in a Northwest Atlantic region currently undergoing rapid changes, the Gulf of Maine and Scotian Shelf. This period spans the late Holocene cooling and recent warming and includes both Indigenous and European influence. We compare environmental records from instrumental, sedimentary, coral, and mollusk archives with ecological records from fossils, archaeological, historical, and modern data, and integrate future model projections of environmental and ecosystem changes. This multidisciplinary synthesis provides insight into multiple reference points and shifting baselines of environmental and ecosystem conditions, and projects a near-future departure from natural climate variability in 2028 for the Scotian Shelf and 2034 for the Gulf of Maine. Our work helps advancing integrative end-to-end modeling to improve the predictive capacity of ecosystem forecasts with climate change. Our results can be used to adjust marine conservation strategies and network planning and adapt ecosystem-based management with climate change. - OPEN ACCESS

The first draft of the United Nations Convention on Biological Diversity (CBD) Post-2020 Global Biodiversity Framework (GBF) includes an unprecedented call for states that have ratified the treaty (Parties) to implement measures to maintain and enhance ecological connectivity as urgent actions to abate further biodiversity loss and ecosystem decline. Considering the challenges that lie ahead for Parties to the CBD, we highlight the ways in which effective and equitable connectivity conservation can be achieved through four transformative changes, including: (1) mainstreaming connectivity retention and restoration within biodiversity conservation sector and influencing sectors (e.g., transportation, energy, agriculture, forestry); (2) mainstreaming financial resources and incentives to support effective implementation; (3) fostering collaboration with a focus on cross-sector collective action; and (4) investing in diverse forms of knowledge (co-)production and management in support of adaptive governance. We detail 15 key actions that can be used to support the implementation of these transformative changes. While ambitious, the transformative changes and associated key actions recommended in this perspective will need to be put in place with unprecedented urgency, coherency, and coordination if Parties to the CBD truly aspire to achieve the goals and targets of the forthcoming Post-2020 GBF in this new decade of biodiversity. - OPEN ACCESS

To effectively combat the biodiversity crisis, we need ambitious targets and reliable indicators to accurately track trends and measure conservation impact. In Canada, the Living Planet Index (LPI) has been adapted to produce a national indicator by both World Wildlife Fund-Canada (Canadian Living Planet Index; C-LPI) and Environment and Climate Change Canada (Canadian Species Index) to provide insight into the status of Canadian wildlife, by evaluating temporal trends in vertebrate population abundance. The indicator includes data for just over 50% of Canadian vertebrate species. To assess whether the current dataset is representative of the distribution of life history characteristics of Canadian wildlife, we analyzed the representation of species-specific biotic variables (i.e., body size, trophic level, lifespan) for vertebrates within the C-LPI compared to native vertebrates lacking LPI data. Generally, there was considerable overlap in the distribution of biotic variables for species in the C-LPI compared to native Canadian vertebrate species lacking LPI data. Nevertheless, some differences among distributions were found, driven in large part by discrepancy in the representation of fishes—where the C-LPI included larger-bodied and longer-lived species. We provide recommendations for targeted data collection and additional analyses to further strengthen the applicability, accuracy, and representativity of biodiversity indicators. - OPEN ACCESS

Understanding the relationship between the height of wind turbines and wildlife fatalities is important for informing and mitigating wildlife collisions as ever taller and denser arrays of wind turbines are erected across the landscape. We examined relationships between turbine height and fatalities of bats and swallows at 811 turbines in Ontario, Canada, ranging from 119 to 186 m tall. We accounted for cut-in speeds, operational mitigation, and taller turbines projecting carcasses farther from the turbine base than shorter turbines. Fatalities of hoary bats (Lasiurus cinereus Palisot de Beauvois, 1796), silver-haired bats (Lasionycteris noctivagans Le Conte, 1831), and big brown bats (Eptesicus fuscus Palisot de Beauvois, 1796) increased with increased maximum blade height of turbines. In contrast, fatalities of little brown bat (Myotis lucifugus Le Conte, 1831) and eastern red bat (Lasiurus borealis Müller, 1776) decreased with increased turbine height. Fatalities of purple martins (Progne subis Linnaeus, 1758) and tree swallows (Tachycineta bicolor Vieillot, 1808) were higher at taller turbines than shorter turbines. However, fatalities of cliff swallow (Petrochelidon pyrrhonota Vieillot, 1817) and barn swallow (Hirundo rustica Linnaeus, 1758) were not associated with turbine height. Our results suggest that varying flight height among species may be one factor affecting collision risk. - OPEN ACCESS

Communities in coastal areas of Canada, including the Great Lakes, face a number of challenges, including increased water level variability and extreme weather events, causing flooding and localized erosion. To effectively respond to these coastal risks requires structured, deliberative approaches with the aim of fostering resilience and contributing to sustainability. A collaborative engagement process was used to explore community challenges. This included a project launch, key informant interviews, meetings, focus groups (agriculture, tourism, youth), and on-line methods (shoreline residents). Participatory social network analysis and theory of change were used for overall sense-making. As a result, community members identified six impact pathways moving forward with climate action: partnerships and collaboration; strategic engagement; water and watersheds; ecosystem-based adaptation; shoreline protection; and education. These themes are consistent with current theory on sustainability and theory of change development. - OPEN ACCESSFreshwater ecosystems show more biodiversity loss than terrestrial or marine systems. We present a systematic conservation planning analysis in the Arctic Ocean drainage basin in Ontario, Canada, to identify key watersheds for the conservation of 30 native freshwater fish, including four focal species: lake sturgeon, lake whitefish, brook trout, and walleye. We created species distribution models for 30 native fish species and accounted for anthropogenic impacts. We used the “prioritizr” package in R to select watersheds that maximize species targets, minimize impacts, and meet area-based targets based on the Convention on Biological Diversity commitment to protect 17% of terrestrial and freshwater areas by 2020 and the proposed target to protect 30% by 2030. We found that, on average, 17.4% and 29.8% of predicted species distributions were represented for each of the 30 species in the 17% and 30% area-based solutions, respectively. The outcomes were more efficient when we prioritized for individual species, particularly brook trout, where 24% and 36% of its predicted distribution was represented in the 17% and 30% solutions, respectively. Future conservation planning should consider climate change, culturally significant species and areas, and the importance of First Nations as guardians and stewards of the land in northern Ontario.

Seagrass meadows are among the most productive and diverse marine ecosystems, providing essential structure, functions, and services. They are also among the most impacted by human activities and in urgent need of better management and protection. In Canada, eelgrass (Zostera marina) meadows are found along the Atlantic, Pacific, and Arctic coasts, and thus occur across a wide range of biogeographic conditions. Here, we synthesize knowledge of eelgrass ecosystems across Canada’s coasts, highlighting commonalities and differences in environmental conditions, plant, habitat, and community structure, as well as current trends and human impacts. Across regions, eelgrass life history, phenology, and general species assemblages are similar. However, distinct regional differences occur in environmental conditions, particularly with water temperature and nutrient availability. There is considerable variation in the types and strengths of human activities among regions. The impacts of coastal development are prevalent in all regions, while other impacts are of concern for specific regions, e.g., nutrient loading in the Atlantic and impacts from the logging industry in the Pacific. In addition, climate change represents a growing threat to eelgrass meadows. We review current management and conservation efforts and discuss the implications of observed differences from coast to coast to coast. - OPEN ACCESS

Climate change is subjecting aquatic species to increasing temperatures and shifting hydrologic conditions. Understanding how these changes affect individual survival can help guide conservation and management actions. Anadromous Pacific salmon (Oncorhynchus spp.) in some large river systems are acutely impacted by the river temperatures and flows encountered during their spawning migrations. However, comparatively little is known about drivers of en route mortality for salmon in smaller coastal watersheds, and climate impacts may differ across watersheds and locally adapted salmon populations. To understand the effects of climate on the survival of coastal sockeye salmon (Oncorhynchus nerka; hísn in Haíɫzaqv), we tagged 1785 individual fish with passive integrated transponders across four migration seasons in the Koeye River—a low-elevation watershed in coastal British Columbia—and tracked them during their relatively short migration (∼13 km) from river entry to spawning grounds. Overall, 64.7% of sockeye survived to enter the spawning grounds, and survival decreased rapidly when water temperatures exceeded 15 °C. The best-fitting model included an interaction between river flow and temperature, such that temperature effects were worse when flows were low, and river entry ceased at the lowest flows. Results revealed temperature-mediated mortality and migration delays from low water that may synergistically reduce survival among sockeye salmon returning to coastal watersheds. - OPEN ACCESS

Environmental management and monitoring must reconcile social and cultural objectives with biodiversity stewardship to overcome political barriers to conservation. Suitability modelling offers a powerful tool for such “biocultural” approaches, but examples remain rare. Led by the Stewardship Authority of the Kitasoo/Xai’xais First Nation in coastal British Columbia, Canada, we developed a locally informed suitability model for a key biocultural indicator, culturally modified trees (CMTs). CMTs are trees bearing evidence of past cultural use that are valued as tangible markers of Indigenous heritage and protected under provincial law. Using a spatial multi-criteria evaluation framework to predict CMT suitability, we developed two cultural predictor variables informed by Kitasoo/Xai’xais cultural expertise and ethnographic data in addition to six biophysical variables derived from LiDAR and photo interpretation data. Both cultural predictor variables were highly influential in our model, revealing that proximity to known habitation sites and accessibility to harvesters (by canoe and foot) more strongly influenced suitability for CMTs compared with site-level conditions. Applying our model to commercial forestry governance, we found that high CMT suitability areas are 51% greater inside the timber harvesting land base than outside. This work highlights how locally led suitability modelling can improve the social and evidentiary dimensions of environmental management. - OPEN ACCESSThe outcomes of environmental impact assessment (EIA) influence millions of hectares of land and can be a contentious process. A vital aspect of an EIA process is consideration of the accumulation of impacts from multiple activities and stressors through a cumulative effects assessment (CEA). An opportunity exists to improve the rigor and utility of CEA and EIA by incorporating core scientific principles of landscape ecology into EIA. With examples from a Canadian context, we explore realistic hypothetical situations demonstrating how integration of core scientific principles could impact EIA outcomes. First, we demonstrate how changing the spatial extent of EIA boundaries can misrepresent cumulative impacts via the exclusion or inclusion of surrounding natural resource development projects. Second, we use network analysis to show how even a seemingly small, localized development project can disrupt regional habitat connectivity. Lastly, we explore the benefits of using long-term historical remote sensing products. Because these approaches are straightforward to implement using publicly available data, they provide sensible opportunities to improve EIA and enhance the monitoring of natural resource development activities in Canada and elsewhere.

Marine plastic is a ubiquitous environmental problem that can have an impact on a variety of marine biota, such as seabirds, making it an important concern for scientists and policy makers. Although research on plastic ingestion by seabirds is increasing, few studies have examined policies and long-term monitoring programs to reduce marine plastic in the Arctic. This paper provides a review of international, national, and regional policies and long-term monitoring programs that address marine plastic in relation to seabirds in the Arctic countries: Canada, the Kingdom of Denmark (Greenland and the Faroe Islands), Finland, Iceland, Norway, the Russian Federation, Sweden, and the United States of America. Results show that a broad range of international, national, regional and local policies address marine debris, specifically through waste management and the prevention of pollution from ships. However, few policies directly address seabirds and other marine biota. Further, policies are implemented inconsistently across regions, making it difficult to enforce and monitor the efficacy of these policies given the long-range transport of plastic pollution globally. To reduce marine plastic pollution in the Arctic environment, pan-Arctic and international collaboration is needed to implement standardized policies and long-term monitoring programs for marine plastic in the Arctic and worldwide. - OPEN ACCESSMicroplastics are globally ubiquitous contaminants, but quantitative data on their presence in freshwater environments are sparse. This study investigates the occurrence, composition, and spatial trends of microplastic contamination in the North Saskatchewan River flowing through Edmonton, Alberta, the fifth largest city in Canada. Surface water samples were collected from seven sites throughout the city, upstream and downstream of the city, and near potential point sources (i.e., a wastewater treatment plant). Samples were spiked with fluorescent microbeads as internal standards and extracted by wet peroxide oxidation and density floatation. Microplastics were found in all samples, ranging in concentration from 4.6 to 88.3 particles·m−3 (mean = 26.2 ± 18.4 particles·m−3). Fibers were the dominant morphology recovered, and most were of anthropogenic origin and chemically identified as dyed cotton or polyester by Raman microspectroscopy. The majority of fragments were identified as polyethylene or polypropylene. No upstream to downstream differences were found in concentration, size distribution, or morphological composition suggesting nonpoint sources of microplastics to the river. This study represents one of the first investigations into the occurrence of microplastics in the freshwater environment in western Canada and will provide a baseline for future studies.

Conservation relies on cooperation among different interest groups and appropriate use of evidence to make decisions that benefit people and biodiversity. However, misplaced conservation occurs when cooperation and evidence are impeded by polarization and misinformation. This impedance influences actions that directly harm biodiversity, alienate partners and disrupt partnerships, waste resources, misinform the public, and (or) delegitimize evidence. As a result of these actions, misplaced conservation outcomes emerge, making it more difficult to have positive outcomes for biodiversity. Here we describe cases where a failed appreciation for cooperation, evidence, or both have eroded efforts to conserve biodiversity. Generally, these case studies illustrate that averting misplaced conservation requires greater adherence to processes that elevate the role of evidence in decision-making and that place collective, long-term benefits for biodiversity over the short-term gains of individuals or groups. Efforts to integrate human dimensions, cooperation, and evidence into conservation will increase the efficacy and success of efforts to conserve global biodiversity while benefiting humanity. - OPEN ACCESSMeaningful engagement is increasingly used as a management tool for understanding the multitude of complex values and potential conflicts around marine conservation and the production of conservation strategies deemed acceptable by local communities. Barachois ponds, akin to coastal lagoons, are recognized coastal wetlands in Nova Scotia, Canada, given their distinct ecosystem services, including provisioning, regulating, and cultural services. This study examines the current discourses around the management of barachois ponds and how an increased understanding of these perceptions held by stakeholders and managers might be used to better inform integrated management of these wetland ecosystems. A mixed-methods research design using Q methodology was employed to acquire data on social perceptions surrounding the management of barachois ponds fringing the Bras d’Or Lake in Cape Breton, Nova Scotia, Canada. Four dominant perspectives were identified: the leave-them-be conservationists, the sustainable developers, the management reformists, and the science-based conservationists. Six key issue themes emerged based on an in-depth examination of these different perspectives and Q sort data. This study found that an increased awareness of the ecological, social, and cultural values attributed to barachois ponds by key stakeholders could play a critical role in better informing wetland management decision-making in Nova Scotia and elsewhere.

Since the implementation of the Canadian Species at Risk Act (SARA) in 2003, deficiencies in SARA and its application have become clear. Legislative and policy inconsistencies among responsible federal agencies and the use of a subjective approach for prioritizing species protection lead to taxonomic biases in protection. Variations in legislation among provinces/territories and the reluctance of the federal government to take actions make SARA’s application often inefficient on nonfederally managed lands. Ambiguous key terms (e.g., critical habitat) and disregard for legislated deadlines in many steps impede the efficacy of SARA. Additionally, the failure to fully recognize Indigenous knowledge and to seek Indigenous cooperation in the species protection process leads to weaker government accountability, promotes inequity, and leads to missed opportunities for partnerships. New legislative amendments with well-defined and standardized steps, including an automatic listing process, a systematic prioritization program, and clearer demands (e.g., mandatory threshold to trigger safety net/emergency order) would improve the success of species at risk protection. Moreover, a more inclusive approach that brings Indigenous representatives and independent scientists together is necessary for improving SARA’s effectiveness. These changes have the potential to transform SARA into a more powerful act towards protecting Canada’s at-risk wildlife. (The graphical abstract follows.) - OPEN ACCESSThis research explores the potential hydroponic systems have for contributing to climate mitigation in fodder agriculture. Using British Columbia (BC) and Alberta as case studies, the study compares greenhouse gas (GHG) emissions and carbon sequestration potential of hydroponically grown sprouted barley fodder to conventional barley grain fodder. GHG emissions were examined through scenarios that assumed Alberta to be the main barley producer, while exploring different situations of BC and Alberta as consumers, distributed/centralized hydroponic systems, and renewable/nonrenewable energy. Carbon sequestration opportunities were examined through scenarios that explored the land sparing potential of transitioning from conventional to hydroponic barley and shifts from tillage to no-tillage practices. Sensitivity analyses were done to examine how changes in hydroponic seed-to-fodder output and energy consumption affect the systems’ climate mitigation potential. The results indicated that incorporating hydroponic systems into barley production has the potential to reduce GHG emissions, given seed-to-fodder output and energy consumption are maintained at certain levels and the systems are powered by renewable energy. Results also showed that hydroponic farming can provide greater carbon sequestration opportunities than simply shifting to no-tillage farming. The research indicates that hydroponic fodder farming could contribute to climate mitigation objectives if complemented with effective energy and land use policies.

The value of paleolimnology in reconstructing and managing ecosystem vulnerability: a systematic map
Vulnerability can measure an ecosystem’s susceptibility to change as a result of pressure or disturbance, but can be difficult to quantify. Reconstructions of past climate using paleolimnological methods can create a baseline to calibrate future projections of vulnerability, which can improve ecosystem management and conservation plans. Here, we conduct a systematic map to analyze the range and extent that paleolimnological published studies incorporated the concept of vulnerability. Additional themes of monitoring, management, conservation, restoration, or ecological integrity were also included. A total of 52 relevant unique articles were found, a majority of which were conducted in Europe or North America since 2011. Common themes identified included management and adaptation, with the latter heavily focussed on climate change or disturbance. From this, we can infer that the use of paleolimnology to discuss the concept of vulnerability is an emerging field. We argue that paleolimnology plays a valid role in the reconstruction of ecosystem vulnerability due to its capacity to broaden the scope of long-term monitoring, as well as its potential to help establish management and restoration plans. The use of paleolimnology in vulnerability analysis will provide a clearer lens of changes over time; therefore, it should be frequently implemented as a tool for vulnerability assessment.
