BLM Statement on Outbreak of Equine Herpes Virus (EHV-1)

The BLM is aware of the recent outbreak of neurologic disease caused by the equine herpes virus (EHV-1) in the Western United States. The Bureau has been working with state and Federal animal health officials to help protect the health and well-being of wild horses and burros on the range, along with those in BLM holding facilities. No BLM-managed wild horses or burros on the range or at BLM facilities are known to have been exposed or affected by the neurologic EHV-1 outbreak at this time. However, the Bureau is consulting and coordinating with animal health officials regarding the movement of wild horses and burros, as well as the scheduling of events such as adoptions that may place horses and burros in contact with horses, burros, or their owners in the domestic horse community. Some lower-risk movements between BLM facilities or BLM facilities and adoption events will continue. Other movements may be cancelled because of concerns regarding potential exposure to EHV-1. At this time, decisions will be made on a local, case-by-case basis in consultation with the BLM’s attending veterinarians and the state veterinarians in the area. All BLM horses and burros that travel interstate do so with valid Certificates of Veterinary Inspection (health certificates) and in accordance with state and Federal animal health regulations. The BLM asks the public to be aware of disease transmission risks and to contact local BLM offices to see if there are any restrictions in place before bringing domestic horses onto BLM-managed public lands.
