Mule deer in the Atlantic Rim North population are part of the Baggs herd unit that is managed for approximately 19,000 animals. These mule deer winter in the pinyon-juniper and sagebrush badlands near Dad, Wyoming and migrate north and east 10–35 mi (16–56 km) to various summer ranges (fig. 22). Many of these deer must navigate coal-bed methane development that is situated along the migration route between their seasonal ranges. In addition to gas development, portions of their summer range overlap with areas of wind-energy development; roadway mortality remains an issue on Highway 789. These data provide the location of migration routes for mule deer (Odocoileus hemionus) in the Clarks Fork population in Wyoming. They were developed from Brownian bridge movement models using 147 migration sequences collected from a sample size of 47 animals comprising GPS locations collected every 2-8 hours.
