Rangeland Scientist-Research Leader
U.S. Department of Agriculture, ARS
Rangeland Ecology

Dr. Svejcar is a Rangeland Scientist and Research Leader with the U.S. Department of Agriculture, Agricultural Research Service in Burns, Oregon. He received his BS (1977) in Biology and MS (1979) in Range Science from Colorado State University, and PhD (1983) in Rangeland Resources from Oregon State University. He joined ARS in early 1983, spending 3 1/2 years in El Reno, Oklahoma, and Reno, Nevada, and has been Research Leader at Burns since August of 1990. His current research is focused on plant responses (at both the individual plant and the community level) to both climate and management. Current or recent past research projects involve western juniper ecology, prescribed fire, seedbed ecology, and grazing impacts on both upland and riparian vegetation.  Dr. Svejcar is also involved in research on annual grass suppressive soil bacteria, and landscape-level responses of vegetation to management practices.
