The U.S. Department of the Interior shared this story about the National Elk Refuge:

The National Elk Refuge in Wyoming works to provide, preserve, restore, and manage winter habitat for the nationally significant Jackson Elk Herd and habitat for endangered species, birds, fish, and other big game animals (like these Bison pictured above), and provide compatible human uses associated with the wildlife and wildlands.
