MULE DEER MIGRATIONS
Protection of Wildlife Migration Corridors.
GTNP biologists established a wildlife migration initiative in the early 1990s, focused on identifying migratory corridors and threats to park wildlife along movement routes and on distant seasonal ranges. One of the initiative’s early projects concentrated on pronghorn migration and was pivotal in defining and protecting the now well-known Path of the Pronghorn. Since 2013, with GTNPF support, the program has discovered eight previously unknown, long-distance migrations of mule deer that summer in the park.
These migration paths, important stopover sites, and associated winter ranges west, east, and south of the park have been delineated through intensive field research, and the program’s emphasis has now shifted to the critical phase of identifying and protecting areas with the most pressing conservation need. Park biologists have developed partnerships with other federal and state agencies as well as private conservations organizations to actively facilitate large-scale habitat conservation where potential migration barriers and threats on seasonal ranges may exist.
