Wildlife, one of the United States' most treasured natural resources, faces a dire future. Changing climate conditions will upend the natural world wild creatures inhabit. Shifts in precipitation, spreading disease, cascading ecological events, and catastrophic events such as wildfires and floods will present wildlife with challenges of a degree and frequency not seen in U.S. history. These shifts in climate will in turn bring to bear great pressure on the heralded U.S. approach to wildlife management. Ill equipped to respond to the jurisdictional fragmentation and scientific uncertainty that will predominate wildlife management in a changing climate, U.S. wildlife managers must seek out new tools to cope with the...
Development of hydrocarbon resources across northwest Canada has spurred economic prosperity but also generated concerns over impacts to biodiversity. To balance these interests, comprehensive land use plans have been used to match targeted management strategies to ecological components deemed valuable by society such as wildlife. I used remote wildlife cameras to measure the response patterns of American marten and black bear to seismic lines, a ubiquitous linear feature in western Canada. Relative to undisturbed forest locations, marten avoid open and wide seismic lines, but not narrow and recovered lines; occupancy at the home range scale also declines with increasing seismic line density. By contrast, black...

The Chisana caribou herd (CCH) is a small international herd occurring in Yukon and Alaska on the Klutlan Plateau and near the headwaters of the White River. During the 1990s through 2003, the herd experienced a long and steady decline in population. Low recruitment, predation, climate, habitat, and harvest pressure likely all contributed to the decline. From 2003 to 2006, a recovery effort designed to increase recruitment and calf survival was conducted. Pregnant cows were captured and enclosed within a holding pen during the last weeks of gestation and a few weeks following calving. During recovery planning and upon the completion of the program, the need for a management plan was stressed by the recovery team....

This thesis is about aboriginal and treaty rights to wildlife and wildlife harvesting, including the right to make decisions about these activities in the Northwest Territories. It deals with the erosion of these rights in the period before 1982 and then traces the protection, redefinition and resurgence of these rights since 1982, when section 35 of the Constitution Act, 1982 was enacted. Section 35 affords constitutional protection to treaty and aboriginal rights including those rights negotiated through modern land claim agreements. This thesis shows that the effect of section 35 jurisprudence and land claims has been to halt the erosion of aboriginal and treaty rights to wildlife and to enhance local control...
Habitat management for ducks has significant implications for the conservation of other species. We hypothesized that, because of their flagship and umbrella characteristics, upland-nesting ducks might be effective surrogate species for songbird and shorebird conservation in the dry mixed-grass prairie. We tested this by comparing effects of habitat management (cattle grazing deferments and field size), distance to other habitat (water, cropland/forage, roads), and vegetation, on the richness and density of ducks, songbirds, and shorebirds in southern Alberta, Canada. There were no consistently similar responses to these habitat characteristics among ducks, songbirds and shorebirds. Despite their conceptual appeal,...
PURPOSE: The implementation of a population management program for Canada geese within the contiguous United States is proposed. In recent years, the numbers of Canada geese that nest and/or reside predominantly within the United States have undergone dramatic population growth, their numbers increasing to levels that are increasingly coming into conflict with human activities and causing personal and public property damage in many parts o the country. Conflicts between people as geese affect or damage several types of resources, including property, human health and safety, agricultural crops, and natural resources. The proposed management measures would be implemented through a regulatory mechanism that would allow...

The Action Plan for Boreal Woodland Caribou Conservation in the Northwest Territories contains general goals and direction for conservation of the boreal population of woodland caribou (boreal caribou) in the Northwest Territories (NWT). The purpose of the Action Plan is to outline actions management authorities in the NWT can take to help conserve boreal caribou. These actions were based on the best traditional, local and scientific knowledge available and are subject to change to accommodate new information and objectives. This draft version was prepared for the public to review and provide feedback about whether these goals are appropriate for the conservation of boreal caribou in the NWT and whether these actions...
A tradeoff between energy gain from foraging and safety from predation in refuges is a common situation for many herbivores that are vulnerable to predation while foraging. This tradeoff affects the population dynamics of the plant-herbivore-predator interaction. A new functional response is derived based on the Holling type 2 functional response and the assumption that the herbivore can forage at a rate that maximizes its fitness. The predation rate on the herbivore is assumed to be proportional to the product of the time that the herbivore spends foraging and a risk factor that reflects the habitat complexity; where greater complexity means greater interspersion of high food quality habitat and refuge habitat,...

The northern goshawk (Accipiter gentilis) is a rare to uncommon forest raptor that is widely distributed in boreal & temperate forests. This report first reviews the goshawk's distribution, taxonomy, biology, habitat, threats to its population, conservation status, and current conservation & research actions related to this species in British Columbia. It then sets out options for management of the goshawk's habitat and a strategy for conservation that would maintain or enhance the goshawk population. Finally, priorities for research are recommended and actions to evaluate the conservation initiative are outlined.
