Dr. Arispe’s extension program focuses on equipping land managers and beef cattle producers with science-based information and appropriate technology that promotes healthy land management. He is also interested in grazing programs and the dynamic impacts that different grazing programs have on natural resources in the sagebrush steppe ecosystem of eastern Oregon. For the past four years, Dr. Arispe has worked with public agencies, non-profit organizations, and private landowners to address threats such as invasive annual grasses, wildfires, and degraded landscapes on western landscapes. sergio.arispe@oregonstate.edu
