BLM Idaho Gathers and Fertility Control Operations

BLM Idaho manages six wild horse herd management areas on approximately 418 thousand acres. The combined appropriate management level for all HMAs in the state is 617 animals. BLM estimates the population on the range to be about 762 (as of July 2019).  

Since 1971, the BLM has removed approximately 3,600 animals from public rangelands in Idaho as part of its efforts to maintain healthy horses and burros on healthy public rangelands. Animals removed from public rangelands are offered to the public for adoption; unadopted animals are cared for on open pastures for the rest of their lives. Below, find on-going and recently completed gathers, organized by HMA.
