The Crow Mesa Mule Deer Study was initiated in 2019 to identify the seasonal movement and distribution patterns of mule deer in the eastern half of Game Management Unit (GMU) 2C. This GPS study builds on nearby studies of mule deer and elk conducted by the Bureau of Land Management, the Southern Ute Tribe, the Jicarilla Apache Nation, and the New Mexico Department of Fish and Game. Migration corridors extended 20 to 75 miles from the winter ranges in GMU 2C to various summer ranges northeast to the Carson National Forest near Chama, and southeast to the San Pedro Parks Wilderness in the Santa Fe National Forest. The Crow Mesa herd relies largely on winter ranges administered by the Bureau of Land Management, where approximately 70% of the population remains year-round (Sawyer 2021). The other 30% migrate through, and summer on an assortment of private, tribal, and U.S. Forest Service lands. Notably, all mule deer migration corridors crossed Jicarilla Apache Nation immediately east of this herd’s winter range. Key management challenges with this deer herd include fence barriers, highway crossings, and habitat loss and human disturbance associated with energy development. These mapping layers show the location of the winter ranges for mule deer (Odocoileus hemionus) in the Crow Mesa/2C population in New Mexico. They were developed from 40 migration sequences collected from a sample size of 12 animals comprising GPS locations collected every 2-8 hours.
