Abstract
In much of the world, the persistence of long-distance migrations by mammals is threatened by development. Even where human population density is relatively low, there are roads, fencing, and energy development that present barriers to animal movement. In order to conserve species that rely on long-distance migration, it is critical to identify existing migration impediments. This paper applies movement models to high-frequency locations of pronghorn (Antilocapra americana) in the Greater Yellowstone Ecosystem to describe the stopover sites associated with anthropogenic development. The findings demonstrate the importance of minimizing development in migration corridors in the future and of mitigating existing pressure on migratory animals by removing barriers, reducing the development footprint, or installing crossing structures.
