Article
Full-text available
Ecological restoration of abandoned, formerly forested farmland can improve the delivery of ecosystem services and benefit biodiversity conservation. Restoration programs can involve removing isolated, non-native trees planted by farmers for fruit or wood. As such “legacy” trees can attract seed dispersers and create microclimates that help native...
Article
Wetlands provide vital wildlife habitat and ecosystem services, but changes in human land use has made them one of the world’s most threatened ecosystems. Although wetlands are generally protected by law, growing human populations increasingly drain and clear them to provide agricultural land, especially in tropical Africa. Managing and conserving...

Full-text available
Since being elected in 2015, Canada’s federal Liberal government has taken steps to overhaul major environment-related laws and policies, including federal environmental assessment (EA) and regulatory processes. During 2016–2017, a government-appointed panel toured Canada and received >1000 suggestions from diverse sectors of society regarding EA r...
Article
Full-text available
Biodiversity is intrinsically linked to the health of our planet—and its people. Yet, increasingly, human activities are causing the extinction of species, degrading ecosystems, and reducing nature’s resilience to climate change and other threats. As a signatory to the Convention on Biological Diversity, Canada has a legal responsibility to protect...
Article
Full-text available
In this article, we examine the role of science in Canada’s federal environmental assessment (EA) regime to illustrate opportunities for improvement. We do not address the application of science in EA practices (i.e., how to do good science within EA processes), which has been thoroughly reviewed by others. Instead, we examine the context for scien...
Article
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 declin...
Article
Full-text available
Wolverines are vulnerable to multiple, widespread, increasing forms of human activity so have become an indicator of conservation success or failure for northern ecosystems. Logistically difficult to research, the last two decades have seen marked changes in technology yielding new insights. We reviewed and synthesized this recent research and aske...
Article
Successful incorporation of scientific knowledge into environmental policy and decisions is a significant challenge. Although studies on how to bridge the knowledge-action gap have proliferated over the last decade, few have investigated the roles, responsibilities, and opportunities for funding bodies to meet this challenge. In this study we prese...

By means of fusing a literature review, case studies, and an organizational capacity and needs assessment survey of connectivity practitioners and stakeholders, this report identifies gaps, barriers, successes, and solutions in the efforts to maintain and restore connectivity in Canada. It is organized as follows: Chapter 1: The Need for a (Re)Con...
Article
Full-text available
To address the ongoing global biodiversity crisis, conservation approaches must be underpinned by robust information. Canada is uniquely positioned to contribute to meeting global biodiversity targets, with some of the world's largest remaining intact ecosystems, and a commitment to co-application of Indigenous ways of knowing alongside scientific,...
Article
Full-text available
Effectively conserving ecosystem services in order to maintain human wellbeing is a global need that requires an understanding of where ecosystem services are produced by ecosystems and where people benefit from these services. However, approaches to effectively identify key locations that have the capacity to supply ecosystem services and actually...
Article
Full-text available
Environmental decision-makers and practitioners need and deserve high quality environmental evidence for effective decision-making. We collate and share a suite of best practices for applied environmental researchers to support their capacity to inform such decision-making processes. This raises a number of important questions: What does “relevant”...
Article
Full-text available
Identifying habitat that is essential to the recovery of species at risk, known as critical habitat, is a major focus of species at risk legislation, yet there has been little research on the degree to which these areas are protected. Here, we first review the provisions for protecting critical habitat on non-federal lands within Canada's Species a...

Participatory approaches, such as community photography, can engage the public in questions of societal and scientific interest while helping advance understanding of ecological patterns and processes. We combined data extracted from community‐sourced, spatially explicit photographs with research findings from 2018 fieldwork in the Yukon, Canada, t...
Article
Full-text available
The future of conservation and human-wildlife relationships in the American West is at a defining moment. The region consists of a mosaic of land-cover types, with large amounts of public land under varying degrees of protection, use, and ownership. This public land provides the foundation for high levels of connectivity and habitat for healthy pop...
Article

Marine spatial planning (MSP) processes seek to better manage ocean spaces by balancing ecological, social and economic objectives using public and participatory processes. To meet this challenge, MSP approaches and tools have evolved globally, from local to national scales. At two International Marine Conservation Congresses (2016 and 2018), MSP p...
Article
The rise in global demand for seafood has led many people to view shellfish aquaculture as an economically and ecologically viable source of seafood. However, interactions with the environment, existing industry, and societal values must be considered to ensure sustainability of this industry. Shellfish aquaculture in British Columbia (BC), Canada,...

British Columbia has the greatest biological diversity of any province or territory in Canada. Yet more and more species in British Columbia are threatened with extinction and require active measures for protection and recovery. The current patchwork of provincial laws and regulations managing wildlife and their habitats has not effectively prevent...
Article
Full-text available
All data layers were converted to raster and resampled at a 5-arc minute resolution (~10 km by 10 km grid). Data were normalized on a scale of 0 to 100 for each data layer, where 0 was equivalent to least need and 100 was equivalent to greatest need for protected areas. This scale enabled us to compare priorities across all conservation principles....

Gaps between environmental science and environmental law may undermine sound environmental decision-making. We link perspectives and insights from science and law to highlight opportunities and challenges at the environmental science–law interface. The objectives of this paper are to assist scientists who wish to conduct and communicate science tha...
Chapter
Global drivers of change are affecting marine ecosystems and the people who depend on them at increasing rates and severities. Yet most marine conservation actions were developed before climate change was widely recognized as a major driver of change. In this chapter, we synthesize categories of marine conservation actions and their relevance at lo...
Article
Full-text available
This perspective documents current thinking around climate actions in Canada by synthesizing scholarly proposals made by Sustainable Canada Dialogues (SCD), an informal network of scholars from all 10 provinces, and by reviewing responses from civil society representatives to the scholars’ proposals. Motivated by Canada’s recent history of repeated...
Article
Full-text available
Globally, mature forests appear to be increasing in biomass density (BD). There is disagreement whether these increases are the result of increases in atmospheric CO 2 concentrations or a legacy effect of previous land-use. Recently, it was suggested that a threshold of 450 years should be used to define mature forests and that many forests increas...

Group size affects many aspects of the ecology and social organization of animals. We investigated group size stability for five primate species in Kibale National Park, Uganda from 1996 to 2011 at three nested spatial scales. Survey data indicated that group sizes did not change for most species, with the exception of red colobus monkeys (Procolob...
Article
While overall numbers of African elephant have declined dramatically in recent times, some populations are now confined to protected areas and are locally overabundant-an undesirable situation for both biodiversity conservation and elephants. In forested protected areas, options to manage elephants are limited because it is difficult to safely appr...

Given accelerating trends of deforestation and human population growth, immediate and innovative solutions to conserve biodiversity are sorely needed. Between 1995 and 2010, we regularly monitored the population size and structure of colobus monkey populations in the forest fragments outside of Kibale National Park, Uganda. Through this monitoring...
Conference Paper
Full-text available
McGill and Montreal rely on ecosystem services – the benefits people obtain from ecosystems. We need services to provide food, energy, clean air and water, climate regulation, places for recreation, and cultural inspiration. Despite our reliance, we are often unaware of where these services come from and their importance to our well-being. This pro...
Article
Full-text available
Predicting variation in animal abundance across time and space has proven very difficult; however, a model exists to predict the biomass of small folivorous primates that has considerable correlative support. This model suggests that the protein-to-fiber ratio of leaves in a habitat can predict folivore biomass. Here we present an experimental test...
Article
Full-text available
The extensive area of degraded tropical land and the calls to conserve forest biodiversity and sequester carbon to offset climate change demonstrate the need to restore forest in the tropics. Deforested land is sometimes replanted with fast-growing trees; however, the consequences of intensive replanting on biomass accumulation or plant and animal...
Article
Threats to species’ persistence are typically mitigated via lengthy and costly recovery planning processes that are implemented only after species are at risk of extinction. To reduce overall threats and minimize risks to species not yet imperiled, a proactive and broad-scale framework is needed. Using data on threats to imperiled species in Canada...
Article
In tropical forest systems tree community change after initial succession (approximately 50–100 years) is very difficult to detect because of the very slow pace of transformation. Since the mid 1980s, there has been an accumulation of evidence that many forests traditionally considered old growth or mature forests have been disturbed. Using 18 year...
Article
Full-text available
Forests are being converted to grasslands and croplands across Africa and natural regeneration of forests is typically poor. In Serengeti National Park, Tanzania, the savanna tree species Acacia polyacantha established in riparian grasslands and forest trees subsequently established within these stands. We examined the conditions for establishment...
