MULE DEER MIGRATIONS
Protection of Critical 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.
