ENTERPRISE, Utah (Reuters) - A Utah county, angry over the destruction of federal rangeland that ranchers use to graze cattle, has started a bid to round up federally protected wild horses it blames for the problem in the latest dustup over land management in the U.S. West.
Close to 2,000 wild horses are roaming southern Utah's Iron County, well over the 300 the U.S. Bureau of Land Management (BLM) has dubbed as appropriate for the rural area's nine designated herd management zones, County Commissioner David Miller said. A horse preservation group disputed Miller's contention, saying the county had between 400 and 500 horses.
County officials complain the burgeoning herd is destroying vegetation crucial to ranchers who pay to graze their cattle on the land, and who have already been asked to reduce their herds to cope with an anticipated drought.
Wild horse preservation groups say any attempt to remove the horses would be a federal crime.
On Thursday, county workers accompanied by a BLM staffer set up the first in a series of metal corrals designed to trap and hold the horses on private land abutting the federal range until they can be moved to BLM facilities for adoption.
"There's been no management of the animals and they keep reproducing," Miller said in an interview. "The rangeland just can't sustain it."
The conflict reflects broader tension between ranchers, who have traditionally grazed cattle on public lands and held sway over land-use decisions, and environmentalists and land managers facing competing demands on the same land.
The Iron County roundup comes on the heels of an incident in neighboring Nevada in which authorities sent in helicopters and wranglers on horseback to confiscate the cattle herd of a rancher they say is illegally grazing livestock on public land.
In Utah, county commissioners warned federal land managers in a letter last month that the county would act independently to remove the horses if no mitigation efforts were launched.
"We charge you to fulfill your responsibility," commissioners wrote. "Inaction and no-management practices pose an imminent threat to ranchers."
The operation was expected to last weeks or months.
"The BLM is actively working with Iron County to address the horse issue," Utah-based BLM spokeswoman Megan Crandall said, declining to comment further.
Attorneys for wild horse preservation groups sent a letter this week to Iron County commissioners and the BLM saying the BLM, under federal law, cannot round up horses on public lands without proper analysis and disclosure.
"The BLM must stop caving to the private financial interests of livestock owners whenever they complain about the protected wild horses using limited resources that are available on such lands," wrote Katherine Meyer of Meyer, Glitzenstein and Crystal, a Washington, DC-based public interest law firm representing the advocates.
The BLM puts the free-roaming wild horse and burro population across western states at more than 40,600, which it says on its website exceeds by nearly 14,000 the number of animals it believes "can exist in balance with other public rangeland resources and uses."
But Deniz Bolbol, a spokeswoman for the California-based American Wild Horse Preservation Campaign, cited 2013 BLM statistics to say there were an estimated 400-500 horses in Iron County, although those federal statistics did not break the numbers down precisely by county.
Wild horse advocates point out that the tens of thousands of wild horses on BLM property pales in comparison with the millions of private livestock grazing on public lands managed by the agency.
"The American public owns this land, it's not just a few ranchers in Iron County, and so the lands need to be managed for all Americans," Bolbol said.
Wild horses have not been culled due to budget constraints, according to Utah BLM officials, who say their herds grow by roughly 20 percent per year.
Pressure on rangeland from the horses may worsen this summer due to a drought that could dry up the already sparse available food supply, according to Miller.
"We're going to see those horses starving to death out on the range," he said. "The humane thing is to get this going now."
Adding to frustration is BLM pressure on ranchers to cut their cattle herds by as much as 50 percent to cope with the drought, Miller said.
A tour of Iron County rangeland, not far from the Nevada border, illustrates the unchecked herds' impact on the land, said Jeremy Hunt, a fourth generation Utah rancher whose cattle graze in the summer in a management area split through its middle by a barbed wire fence.
On the cattle side of the fence, the sagebrush and grass landscape is thick and green. The other, where a group of horses was seen on Thursday, is scattered with barren patches of dirt and sparse vegetation.
"This land is being literally destroyed because they are not following the laws that they set up to govern themselves," said Hunt, who also works as a farmhand to make ends meet for his family of six.
"I want the land to be healthy and I want be a good steward of the land," he added. "But you have to manage both sides of the fence."
