FWS will make a final determination on the proposal to establish a nonessential experimental population (NEP) of the gray wolf (Canis lupus) in Colorado, under section 10(j) of the Endangered Species Act of 1973, as amended (Act). Establishment of this NEP will facilitate the State of Colorado’s reintroduction of gray wolves and provide for allowable legal incidental taking of the gray wolf within the NEP area. The best available data indicate that reintroduction of the gray wolf into Colorado is biologically feasible and will promote the conservation of the species. We held four public information meetings during a 60-day public comment period. This final determination is based on consideration of public comments and peer review received in response to our proposed rule.
