We evaluated this relationship in the Oregon Cascade Mountains. Despite similar biomass of northern flying squirrels (Glaucomys sabrinus) (169 ± 13.9 g/ha) and deer mice (Peromyscus maniculatus) (160 ± 18.8 g/ha), flying squirrels dominated the breeding season diet based on both biomass (49...

The spines makeBerberisan ideal bush to keep out intruders and it is often used around vulnerable windows. As a hedge, it will deter animal intruders as well as people. It is deer-tolerant too. But plants likeBerberiswhose seeds can be spread by birds often spread fast and become invasive ...
We studied responses of Columbian white-tailed deer (Odocoileus virginianus leucurus) to cattle and sheep in western Oregon because of viability concerns. We used radio-telemetry, observations from horseback, and searches with a trained dog to determine fawning habitat, dam home ranges, and habitat...
In addition, BLM staff requested that we include systems that are important to habitat of mule deer (Odocoileus hemionus) and migratory birds, although those species were not assessed here. These systems included aspen woodland (Populus tremuloides), black sagebrush (Artemisia nova), low sagebrush ...
