Migratory ungulates are susceptible to effects of development along their migration corridors. For example, impermeable barriers such as tall fences preclude movements of migratory populations. Most forms of development in the West, however, represent semipermeable barriers, and their influences on migration remain unclear. This study entails using fine-scale mule deer movement data to evaluate the influence of anthropogenic barriers on the animals’ migratory behaviors. Our efforts include evaluating the rate of travel, duration of stopovers, and route fidelity of deer migrating across a gradient of development in Southwest Wyoming. In FY2014, we analyzed mule deer movement metrics and use of migration stopover...

This is the seventh report produced by the U.S. Geological Survey (USGS) for the Wyoming Landscape Conservation Initiative (WLCI) to detail annual activities conducted by the USGS for addressing specific management needs identified by WLCI partners. In FY2014, there were 26 projects, including a new one that was completed, two others that were also completed, and several that entered new phases or directions. The 26 projects fall into several categories: (1) synthesizing and analyzing existing data to identify current conditions on the landscape and using the data to develop models for projecting past and future landscape conditions; (2) monitoring indicators of ecosystem conditions and the effectiveness of on-the-ground...
