SALT LAKE CITY (AP) — Federal officials plan to round up thousands of wild horses and burros across six Western states starting Monday.
The roundups will take place through February on drought-stricken range lands in Idaho, New Mexico, Nevada, Oregon, Utah and Wyoming.
Contractors for the Bureau of Land Management will use helicopters plus bait- and water-trapping methods to corral 3,500 wild horses and burros, officials said.
In addition, more than 900 other horses will be captured for birth control injections and returned to range lands.
The government is already holding 47,000 horses, most of them on green pasture in the Midwest. Bureau of Land Management officials said it was a popular misconception that they send horses to slaughterhouses. The animals are protected under the 1971 Wild Free-Roaming Horses and Burros Act.
A small number of horses are put up for adoption, but most horses are kept until their final days in permanent corrals, officials said.
Owners of adopted horses must swear under the penalty of law that they do not plan to send horses to slaughter, said Heather Emmons, a BLM spokeswoman in Reno, Nev.
The BLM's ability to care for ever-rising numbers of wild horses is a decision left to Congress, she said. The BLM says there are 11,000 more wild horses roaming public lands across the West than belong there.
In all, there are 37,300 wild horses and burros on public range lands across 10 Western states, the government says.
Officials said they have no choice but to cull wild horse herds. With virtually no predators, they say, the herds can double in population every four years.
Horse advocacy groups have been critical of government roundups and what they call the rough treatment of horses gathered up.
"They aren't placing enough wild horses through adoption so they need to put a freeze on roundups," said Anne Novak, executive director of Berkeley, Calif.-based group Protect Mustangs. "Killing them is not a solution. Selling them to slaughter is not a solution. They need to be responsible for their actions and stop the gluttony of roundups at taxpayer expense."
BLM officials say comments suggesting they kill horses are irresponsible.
