The diverse ecosystems and mosaic landscapes of BLM Colorado’s public lands provide habitat for more than 671 species of fish and wildlife. Colorado’s broad diversity of wildlife is composed of 473 bird species, 130 mammal species, 49 reptile species, 69 fish species and 18 amphibian species. BLM Colorado also hosts a number of invertebrates, including mollusks and crustaceans. Colorado is nationally recognized for its stream fishing and big game hunting.
The BLM's wildlife habitat management goal is to maintain a diversity of fish and wildlife species and habitat and conserve special status plant and animal species on public land. The BLM accomplishes this goal by restoring, maintaining and enhancing habitat productivity and quality as a part of its multiple use mission.
