The Bureau of Land Management's Elko District Office, in close coordination with the Nevada Department of Agriculture, Nevada Department of Wildlife, Simplot Land and Livestock, and local residents, will take part in the operation.
The impoundment is scheduled to begin on Friday and is expected to take three to four days.
The work will be conducted by an experienced BLM gather contractor.
The horses are believed to be released or stray and descendents of horses of local property owners. Over the years the herd has grown in size and is causing considerable impacts to bureau-managed public land resources.
The contractor will set up holding corrals on nearby private land owned by Simplot Land and Livestock.
Once gathered, the horses will be transported to the temporary holding corrals and immediately be placed under the jurisdiction of the State of Nevada.
Under Nevada estray laws, the state will try to establish legal ownership and offer the horses back to the lawful owner.
Owners of the animals would have to own a registered brand in Nevada or provide legal bill of sale or other descriptive documents.
The Nevada Department of Agriculture will accept responsibility of all unclaimed horses pursuant to the state's estray laws.
