Current Research

I lead a research team that is responsible for discovering and synthesizing information that is needed to conserve threatened, endangered, and sensitive forest carnivores throughout the Rocky Mountains. The research topics that I currently study include: 1) Seasonal changes in resource use of Canada lynx and wolverines; 2) Canada lynx movements and connectivity in the north-central Rockies; 3) Canada lynx population viability in the northern Rockies; 4) Determining the response of lynx and wolverines to winter recreation; and 6) Determining how oil and gas development affects ferruginous hawks in Wyoming based on GPS telemetry and conservation genetics.

Research Interests

My current research interest concerns the management and conservation of Canada lynx, wolverines, and other sensitive species. Lynx and wolverine are highly mobile and depend on broad landscapes to meet their resource needs. Thus, my interest includes multi-scale evaluations of resource selection, forest carnivore movements and connectivity, factors affecting population viability, the effects of forest management, recreation and other human-induced impacts on species persistence, developing detection and monitoring methods for forest carnivores, and determining the effects of climate change on lynx and wolverine. I also have had a life-long interest in raptors and their management. I am particularly interested in helping agencies and industry develop energy reserves in ways that also facilitate raptor conservation.

Past Research

Many aspects of meso-carnivore (lynx and wolverine) ecology in the contiguous United States were unknown when we initiated our research program in 1997. Land managers were in the difficult position of having to prescribe management actions without knowledge regarding their potential impacts to meso-carnivores. Results from our studies have informed lynx management across millions of acres of federal lands. These results are helping land managers to sustain lynx populations within a multi-use management context. Winter recreation is a major industry across the western U.S. that contributes over a billion dollars annually to local economies. Results from our studies that investigate how lynx and wolverines respond to winter recreation helps ski areas and state/federal land managers to administer recreation in ways that also conserves lynx and wolverines. Finally, the U.S. is actively trying to reduce its dependence on imported energy. There is also concern regarding the impacts of climate change from carbon emissions which has increased interest in alternative energy. Results from our ongoing research will help industry and government understand the impacts of domestic energy development on ferruginous hawks and golden eagles. This information provides a basis for land managers to design energy developments in ways that minimize impacts to prairie-nesting raptors.

Why This Research is Important

Since 1990, I have researched many aspects of goshawk management and conservation.
