50 CFR § 25.11 - Purpose of regulations.
(a) The regulations in this subchapter govern general administration of units of the National Wildlife Refuge System, public notice of changes in U.S. Fish and Wildlife Service policy regarding Refuge System units, issuance of permits required on Refuge System units and other administrative aspects involving the management of various units of the National Wildlife Refuge System. The regulations in this subchapter apply to areas of land and water held by the United States in fee title and to property interests in such land and water in less than fee, including but not limited to easements. For areas held in less than fee, the regulations in this subchapter apply only to the extent that the property interest held by the United States may be affected. The regulations in this subchapter also apply to and govern those areas of the Rocky Mountain Arsenal over which management responsibility has been transferred to the U.S. Fish and Wildlife Service under the Rocky Mountain Arsenal Act of 1992 (Pub. L. 102-402, 106 Stat. 1961), before their establishment as a refuge and inclusion in the National Wildlife Refuge System.
(b) All national wildlife refuges are maintained for the primary purpose of developing a national program of wildlife and ecological conservation and rehabilitation. These refuges are established for the restoration, preservation, development and management of wildlife and wildlands habitat; for the protection and preservation of endangered or threatened species and their habitat; and for the management of wildlife and wildlands to obtain the maximum benefits from these resources.
