The Cody elk herd migrates across rugged country on the eastern side of the Absaroka Mountains near Cody, WY. This large herd of 6,000-7,000 animals winters in foothill habitat to the south and west of Cody. There are three core winter areas, namely the valleys formed by the North and South Fork of the Shoshone River and the headwaters of the Greybull River north to Meeteetse creek. In spring, the elk that winter along the North Fork of the Shoshone generally follow the river west towards the park, some of them branching up Eagle Creek and other tributaries. The elk that winter in the South Fork of the Shoshone follow it upstream in spring, eventually heading west up Ishawooa Creek and into the Thorofare and Yellowstone National Park. The elk that winter in the upper Greybull River drainage also summer in the Thorofare, but their journey is more arduous. From winter range, they climb nearly 3,000 vertical feet, up and over Needle Mountain, before descending down to the Shoshone River, only to climb again out of the river up to the Thorofare for summer. Some animals in this herd make migrations as far as 117 miles, while others make shorter migration; the mean migration length is 58 miles. Like the Clarks Fork herd, this herd is also partially migratory, with resident animals typically exhibiting higher levels of calf recruitment. Since most of the migrations of this herd cross public forest and park land, the most pressing management issue is to maintain strong collaborative relationships with the large landowners that privately manage much of the winter range these elk return to each autumn. These data provide the location of migration routes for Elk (Cervus canadensis) in the Cody herd in Wyoming. They were developed from Brownian bridge movement models using 109 migration sequences collected from a sample size of 28 animals comprising GPS locations collected every 2-8 hours.
