BLM Idaho Wild Horse and Burro Herd Management Area Poly

Description

This data shows wild horse and burro herd areas in Idaho. Wild horses are managed in accordance with the Wild Free-Roaming Horse and Burro Act of 1971, which gives the Bureau of Land Management (BLM) responsibility to protect wild horses while ensuring their populations are in balance with the ecological capacity of public lands. This data set contains nine herd areas (HA). Five herd areas are located in the Boise District, one HA is located in the Twin Falls District and three HAs are located in the the Idaho Falls District. All of Idaho's herd areas are managed for wild horses; there are no burros. A campaign started in the 1950's to protect wild horses and burros led to aerial flight surveys in 1971 to determine where wild horses and burros occurred. On Dec. 18, 1971, Congress passed the Wild Free-Roaming Horses and Burros Act. At that time, wild horses and burros were found roaming across 53.8 million acres of Herd Areas, of which 42.4 million acres were under the Bureau of Land Management's (BLM) jurisdiction. Herd Areas were carried forward in land use plans and determinations were made as to whether or not to manage animals on these federal lands. Today the BLM manages wild horses and burros in 179 subsets of these Herd Areas (known as Herd Management Areas) that comprise 31.6 million acres, of which 26.9 million acres are under BLM management. No specific amount of acreage was “set aside” for the exclusive use of wild horses and burros under the 1971 Wild Free-Roaming Horses and Burros Act. The Act directed the BLM to determine the areas where horses and burros were found roaming and to manage them "in a manner that is designed to achieve and maintain a thriving natural ecological balance on the public lands." The law also stipulated in Section 1339 that "Nothing in this Act shall be construed to authorize the [Interior] Secretary to relocate wild free-roaming horses or burros to areas of the public lands where they do not presently exist." Of the 22.2 million acres no longer managed for wild horse and burro use 6.7 million acres were never under BLM management. Of the 15.5 million other acres of land under BLM management (numbers current as of July 25, 2011): 48.6 percent (7,522,100 acres) were intermingled ("checkerboard") land ownerships or areas where water was not owned or controlled by the BLM, which made management infeasible; 13.5 percent (2,091,709 acres) were lands transferred out of the BLM's ownership to other agencies, both Federal and state through legislation or exchange; 10.6 percent (1,645,758 acres) were lands where there were substantial conflicts with other resource values (such as the need to protect habitat for desert tortoise); 9.7 percent (1,512,179 acres) were lands removed from wild horse and burro use through court decisions; urban expansion; highway fencing (causing habitat fragmentation); and land withdrawals; 9.6 percent (1,485,068 acres) were lands where no BLM animals were present at the time of the passage of the 1971 Act or places where all animals were claimed as private property. These lands in future land-use plans will be subtracted from the BLM totals as they should never have been designated as lands where herds were found roaming; and 8.0 percent (1,240,894 acres) were lands where a critical habitat component (such as winter range) was missing, making the land unsuitable for wild horse and burro use, or areas that had too few animals to allow for effective management. Since Herd Area boundaries were set by Congress they will not be updated. For more information contact us at blm_id_stateoffice@blm.gov.
