My current work centers on several aspects of ungulate ecology, including the role of ungulates as disturbance agents and how they are in turn impacted by human disturbance, climate change, and land use change; developing resource selection models for ungulates; interactions of grazing by cattle, deer, and elk with a suite of responses (shrubs, native bees) in a restored riparian area supporting endangered salmonids; and factors driving hunter distributions and their impacts on prey energetics and distributions.
Past research topics have included developing and validating habitat use models for elk, greater sage-grouse, wolverine, and other species of concern; elk response to fire and roads/traffic; greater sage-grouse as an umbrella species; and regional assessments of habitat threats, especially in the sagebrush ecosystem.
Ungulates are among the most common disturbance agents on public lands of the western U.S.; moreover, elk and mule deer are of high social and economic value, and cattle grazing remains a key use of western rangelands. Better understanding of the key factors driving distributions of deer, elk, and cattle across multiple seasons can help inform land management decisions about issues such as forage improvements, grazing in riparian areas, and road access. For example, strategic road management can help re-distribute elk on national forests and private lands, increase viewing and hunting opportunities, and decrease damage to croplands. The role of cattle vs. deer and elk in affecting riparian restoration for endangered fish is little studied; new information from our studies can guide future riparian monitoring and restoration.
