The Charles M. Russell Wildlife Refuge spans more than a million acres as it winds along 125 miles of the Missouri River. At the request of the U.S. Fish and Wildlife Service and with support from the Richard King Mellon Foundation, the Fund joined with the American Prairie Foundation, Bureau of Land Management and state of Montana to conserve more than 50,000 acres for the refuge. The agreement included the purchase of 26,000 acres of grazing permits to protect sensitive wildlife habitat that hosts sage grouse, mule deer and elk.
