The BLM has been evaluating proposals for locating solar facilities on public lands across the Great Basin, including Oregon. The implications for large scale solar development on native ungulate species in Oregon has not be thoroughly investigated. Our objective was to identify priority habitats, and movement corridors used by mule deer in the south central Oregon for conservation of habitats and populations of mule deer prior to siting of solar facilities. We used locations of 158 mule deer obtained between 2015 and 2024 to identify priority habitats on seasonal ranges, migration corridors, and stopover locations of mule deer. Those data provide a crucial opportunity to predict impacts, via modeling, on mule deer prior to siting of those facilities. We are using resource selection functions and Brownian bridge movement models to identify habitats of high priority conservation, movement corridors, and stopover locations. The predicted direct and indirect impacts of solar development will be evaluated and used to inform mitigation as necessary to minimize habitat lost to solar development or for barriers created as a result of those facilities
