A boreal songbird's 20,000 km migration across North America and the Atlantic Ocean

Geolocation technology allowed researchers to track Blackpoll Warblers as they undertook their annual migration cycle. These 12 gram birds double their body weight before undertaking an astonishing journey, migrating over 3,000 km over the Atlantic Ocean to overwinter in South America before returning to breed. Blackpoll Warblers populations are declining and identifying key overwintering and breeding sites may be key to their survival. As a high-quality breeding site, the protection of Canada's boreal forest is critical to saving this amazing songbird

Securing a Wild Future - Planning for Landscape-Scale Conservation of Yukon's Boreal Mountains

The cumulative effects of unplanned development can result in the piecemeal erosion of ecological values, with significant impacts on wildlife populations. The capacity of Yukon's Boreal Mountains to accommodate additional growth of the development footprint before ecological values and traditional economies are significantly compromised is unknown. Just a single road through a large, continuous block of intact habitat opens an area up to further resource use, wildlife exploitation, land conversion, motorised and non-motorized recreation, and continued expansion of the road network. This study examines the gaps in existing protection and opportunities and priorities for proactive landscape-scale conservation across approximately 290,000 square kilometres of the southern Yukon using the BEACON’s benchmarking modelling approach.

Bighorn backcountry of Alberta, Protecting vulnerable wildlife and precious waters

A scientific analysis that identified a conservation gem nestled beside the two crown jewels of the Rocky Mountain national park system. The area, known as the Bighorn Backcountry, lies just east of Banff and Jasper National Parks in Alberta and represents one of the most ecologically important areas in the province’s Eastern Slopes region. Based on findings about the importance of this region to wildlife, clean water and recreation, WCS Canada is calling on the Alberta Government to designate the area as a Provincial Wildland Park in keeping with its recent commitment to conserve at least 17 percent of the province’s land base.

Strategic Conservation Assessment for the Northern Boreal Mountains of Yukon and British Columbia

This document provides much of the information needed to direct WCS Canada’s work in the Northern Boreal Mountains site in the next 5 to 10 years. It outlines the scope and components of the regional conservation challenge, and provides an overview of our opportunities for future and long-term engagement through field-based science, administrative process, policy and regulatory review, and political engagement.

Camps on the Land - Considerations and Opportunities in the Yukon and northern British Columbia

For First Nation communities in Canada 'camps on the land' are a strong force for community development, bringing youth and elders together in a non-urban environment where traditional knowledge and skills can be passed on among generations through direct experience. This report summarizes the key considerations in developing 'camps on the land', based on the experiences of First Nations in the Yukon and northern British Columbia.

ABS Working Paper No.3 A Review of Best Practices and Principles for Bison Disease Issues - Greater Yellowstone and Wood Buffalo Areas

This American Bison Society working paper discusses the threat of disease to wild bison populations in the greater Yellowstone (GYA) and Wood Buffalo areas (GWBA) of the US and Canada. The authors used these regions as case studies to highlight management issues and explore strategies for stakeholder engagement. Based on these studies, they made recommendations for diseased bison management to inform bison restoration.

Application of herd viability models for boreal woodland caribou (Rangifer tarandus caribou) to a Northern Mountain Caribou Herd

Caribou (Rangifer tarandus) herds of the northern mountain population in British Columbia and Yukon are facing increased human development and habitat alteration. Managers need to better understand at what stage these changes will become a conservation issue. Historical declines in numerous herds of the Boreal Woodland Caribou population prompted development of three models relating herd viability to human footprint and proportion of the land base changed to early-seral conditions by natural or human disturbance. This study applies these models to the range of a northern mountain herd, the Carcross Caribou Herd (CCH), in southcentral Yukon, to understand whether and how the boreal models could be used in a northern mountain context.

Density estimation for small mammals from live trapping grids - rodents in northern Canada

While robust estimates of population density are crucial for management agencies and quantitative ecologists, the best way to convert population estimates of livetrapped small mammals to population density is not clear. This study compares four density estimators for three boreal forest and three tundra rodent species to test for relative differences.

What factors determine cyclic amplitude in the snowshoe hare cycle

While snowshoe hares (Lepus americanus) exhibit a relatively regular population cycle of 9-10 years in much of their North American range, they experience large variations in cyclic amplitude. This study considers four hypotheses (weather, forest succession, plant defense, and predator hypotheses) that could explain this variation for sites within Alaska, Yukon, Northwest Territories, and British Columbia.

Synchrony in the snowshoe hare (Lepus americanus) cycle in northwestern North America, 1970-2012

Snowshoe hares (Lepus americanus) fluctuate in 9–10 year cycles throughout much of their North American range. Regional synchrony has been assumed to be the rule for these cycles, so that hare populations in virtually all of northwestern North America have been assumed to be in phase. This study examines the data on hare numbers and fur returns of the Canada lynx (Lynx Canadensis) in the boreal forest regions of Alaska, Yukon, Northwest Territories, and northern British Columbia to describe synchrony in the time window of 1970–2012.
