Institute of Range and the American Mustang Mission Statement.

DBA The Black Hills Wild Horse Sanctuary 


The Institute of Range and American Mustang (IRAM) founded by Dayton O. Hyde in 1988 is a 501(c)3 non-profit corporation registered in the state of South Dakota.  IRAM manages the Black Hills Wild Horse Sanctuary and owns 11,000 acres of private land dedicated to range preservation and a balanced ecosystem located in the Southern Black Hills. The principle mission was to save this sacred land with Native American and Early Pioneer history from development, preserve the natural habitat of the ingenious wildlife on the land and provide a home for unwanted American Mustangs.


IRAM’s finest gift is the Black Hills Wild Horse Sanctuary, whose purpose is to provide not only freedom for unadoptable and unwanted wild horses, but also a research area dedicated to solving wild horse herd management that will contribute to the well-being of wild horses everywhere.


The Sanctuary and its staff are devoted to the spirit of the wild mustangs by giving America’s unwanted wild horses a quality life of freedom.  The Black Hills Wild Horse Sanctuary is a showcase where large herds of wild horses run free in a natural habitat. IRAM continues their principles for the conservation of the land, native plants and wildlife and the preservation of our western heritage including local indigenous people and America’s Wild Mustang!
