BLM preparing for southern Wyo. wild horse roundup

The Bureau of Land Management is preparing to round up some wild horses in southern Wyoming next summer. The BLM announced Wednesday that it would take public comment on a proposal to gather horses in Sweetwater and Carbon counties on lands that stretch from Interstate 80 south to the Colorado border. The horses may be given fertility treatments and then released back into the wild. Last month, a citizen advisory panel recommended that the BLM should consider sterilizing some mares to control booming mustang populations and protect rangelands. The agency has long struggled with how to manage growing horse herds on public lands, which can double naturally within five years if left unchecked. It currently has more horses in captivity than are left roaming the range
