Dr. Davies is a Rangeland Scientist with the USDA-Agricultural Research Service at the Eastern Oregon Agricultural Research Center in Burns, OR. Dr. Davies research focuses on vegetation patterns, disturbance ecology, climate and management influences on rangeland vegetation, sagebrush-bunchgrass community ecology, and invasive plant prevention, control, and ecology.

Current Research Projects:

Resource islands and vegetation heterogeneity in sagebrush plant communities
Ecology and prevention of exotic annual grass invasion
Impacts of exotic annual grass invasions
Identifying characteristics of invasion resistant plant communities
Revegetation of exotic annual grass invaded plant communities
Prior disturbance impacts on subsequent disturbances
Pre- and post-fire management influence on plant community ecology
Wyoming and mountain big sagebrush plan community ecology
Influence of disturbances on wildlife habitat in the sagebrush steppe
Insect response to distrubances in sagebrush plant communities
Feral (wild) horse impacts to riparian areas and adjacent uplands
Influence of climate and soils on native vegetation cover, density, and production
