The Grizzly Bear Recovery Plan was established in 1993 and revised in 2006. This plan guides management when the grizzly is on the threatened species list. Bear managers will use the Grizzly Bear Conservation Strategy if the GYE population of grizzly bear is removed from the threatened and endangered species list. The Conservation Strategy is the long-term guide for managing and monitoring the grizzly bear population and assuring sufficient habitat to maintain recovery. It emphasizes coordination and cooperative working relationships among management agencies, landowners, and the public to ensure public support, continue the application of best scientific principles, and maintain effective actions to benefit the coexistence of grizzlies and humans. It incorporates existing laws, regulations, policies, and goals. The strategy has built-in flexibility: Grizzly Bears & the Endangered Species Act - Yellowstone National Park (U.S. National Park Service)
