Current Research

My research focuses on understanding the patterns and processes behind the distribution of animals across a landscape. I am interested in how biotic and abiotic factors influence the habitats and resources that animals use, and in how the ways in which we choose to analyze these data influence our understanding.  My current projects include modeling the distribution and habitat selection of Canada lynx and fisher in the northwestern Rocky Mountains, examining the movement and migration of ferruginous hawks in Wyoming, and understanding Canada lynx response to recreation and beetle outbreaks in Colorado.

    The management of Canada lynx habitat is an issue that has generated much debate and litigation across the Northern (Montana, Idaho) and Southern (Colorado, Wyoming) Rocky Mountains. This species depends almost exclusively on snowshoe hare for food during winter, and this prey species is sensitive to changes in forest composition and structure. Research conducted by scientists at the Rocky Mountain Research Station, in collaboration with universities and local forest managers, is central in resolving management impasses by learning how changes in forest structure and composition can be implemented in ways that enhance the ability of Canada lynx to produce kittens.

    Spruce-bark beetles impacted about 480,000 acres of spruce-fir forests in southern Colorado and are spreading at the rate of 100,000 acres annually.  A central question is how to salvage for timber production insect-impacted forests in ways consistent with the management and conservation of Canada lynx, a federally-listed species.

    Over the past decade and a half, raptors nesting in prairie ecosystems have been subject to sharp increases in nearby energy development activity. This research documents how nesting ferruginous hawks forage in oil and gas energy fields based on GPS telemetry. The purpose is to help managers and companies reflect conservation needs of this species in the management and arrangement of energy-development infrastructure.   
    By 2013, a spruce beetle outbreak impacted 85% of the mature spruce-fir forests on the Rio Grande National Forest. These spruce-fir forests provided some of the highest quality lynx habitat in the state. The goal of this project is to research the forest structures and compositions that lynx and snowshoe hare depend within landscapes altered by spruce bark beetle outbreak, in relation to increased post-beetle forest management activities from timber salvage.
