A report recently released by the Cloud Foundation, a Colorado-based wild horse advocacy group, alleges that the Bureau of Land Management’s (BLM) Salt Lake Regional Wild Horse and Burro Center holding facility in Herriman, Utah, is housing mustangs in unsanitary conditions. The BLM is currently reviewing the allegations to determine what, if any, action is necessary.

The BLM is tasked with managing more than 33,000 free-roaming wild horses and burros that reside on ranges in Western states. The agency also manages another 40,000 horses placed in long- or short-term holding facilities after the animals have been removed from the range during periodic roundups.

Last week, written and video reports prepared by wild horse advocate Lisa Friday and released by the Cloud Foundation, allege that the animals at the Harriman facility are kept in muddy, urine-soaked pens and that some horses experienced difficulty moving through the muck located there. The animals did have access to "good supplies" of food and water, according to the report.

BLM spokesperson Celia Boddington said the agency was reviewing the material contained in the report
