The Wild Sheep Foundation praised Interior Department and U.S. Fish and Wildlife Service recommendations issued after a review of the National Wildlife Refuge System. Officials announced the findings on November 6 at Audubon National Wildlife Refuge north of Bismarck, North Dakota, with Interior Secretary Doug Burgum and Service Director Brian Nesvik present. The review used staff surveys, site visits, and talks with agency staff and partners and called for more active habitat work, stronger partnerships, and more field-based management. Several refuges including Nevada's Desert National Wildlife Refuge, created in 1936 on about 1.6 million acres to conserve desert bighorn sheep, host wild sheep. The Bozeman, Montana group said it will work with the Service as the recommendations are put into practice.
