Sergio Arispe serves as an Associate Professor in the Department of Animal and Rangeland Sciences within Oregon State University's College of Agricultural Sciences. He is based at the Malheur County Extension Office in Ontario, Oregon, where he conducts research and extension activities focused on rangeland management and beef cattle production systems in eastern Oregon's sagebrush steppe ecosystem.
Dr. Arispe's educational background includes a Ph.D. in Animal Biology from the University of California, Davis (2012), an M.S. in Agricultural Education from Texas A&M University (2003), and a B.S. in Animal Science from Texas A&M University-Kingsville (2001).
His research program centers on the interplay between nutrition and reproduction in ruminants, with particular emphasis on grazing programs and their dynamic impacts on natural resources in the sagebrush steppe ecosystem of eastern Oregon. His work integrates advanced technologies including Structure-from-Motion (SfM) and LiDAR from Unmanned Aerial Vehicles for vegetation monitoring and biomass estimation. He has developed innovative approaches to fine fuels management using dormant season grazing to address invasive annual grasses and improve rangeland health.
Analysis of his publication record reveals a strong focus on medusahead control, fine fuel management, invasive species ecology, and the application of remote sensing technologies in rangeland assessment. His work spans both fundamental ecological research and practical applications for land managers, with increasing emphasis on landscape-scale approaches to rangeland conservation.

Dr. Arispe actively accepts graduate students for the Animal and Rangeland Sciences Department and has secured funding from multiple sources including Oregon Beef Council, USDA-NIFA, and the US Department of Interior for projects related to fine fuels management, rangeland restoration, and beef cattle production systems. His extension program focuses on equipping land managers and beef cattle producers with science-based information that promotes healthy land management on both private and public lands.
He has developed numerous educational resources including the "Oregon's Outback: A Sustainable Rangeland-Based Beef Production Video Library," the "Nutrient Management and Planning Tool," and regular newsletters addressing livestock, fire, and rangeland management issues for Malheur County producers. His collaborative approach involves working with multiple stakeholders including ranchers, federal land managers, and international partners like the University of León in Spain.
