Grizzly Bear Recovery Zone for the Greater Yellowstone Ecosystem The Grizzly Bear Recovery Zone (GBRZ) for the Greater Yellowstone Ecosystem (GYE) delineates the area inside the GYE where demographic and habitat criteria were applied, monitored, and evaluated to achieve recovered status of the Yellowstone grizzly bear population. The GBRZ was established by the U.S. Fish and Wildlife Service (USFWS) in 1993 as part of the Recovery Plan for grizzly bears in the lower 48 conterminous United States. The recovery zone boundary identifies the known distribution of bears at that time and encompasses seasonal habitats needed to support a recovered population. The GYE recovery zone spans portions of Montana, Idaho and Wyoming and includes parts of 5 National Forests (Beaverhead-Deerlodge,...

Recovery zones represent the five known populations in the lower 48 United States including the Northern Continental Divide, Greater Yellowstone, Cabinet-Yaak, Selkirk, and North Cascade populations. The bitterroot ecosystem in Idaho represents the possible sixth population. The grizzly bear once ranged across a large portion of western North America from northern Mexico to Alaska and across much of Canada. Current distribution in the lower 48 United States is reduced to less...
