Research Interests

My research includes the economics of hunting and the conservation of habitats as a result of that economic input. My work, to date, primarily involves the American model of wildlife management, but also includes studies from South Africa, Zimbabwe, Argentina, Spain, and New Zealand.

I also continue to study changes in mountain environments, primarily caused by human activities. These activities include grazing impacts, fire suppression, forestry, subdivision placement, and recreation. These studies are primarily in the Rocky Mountain region of the Greater Yellowstone Ecosystem.

Snow science continues to interest me. Research, conducted with other faculty and with students, includes the geography of snow stability and avalanches, over space and time. This research has focused on the local mountain areas where field work is most feasible.
