Interior Secretary Ken Salazar has proposed a plan that would expand the capture and confinement of wild horses. Under his plan, tens of thousands of additional mustangs (mares and neutered stallions) would be rounded up and sent to holding facilities in the Midwest and Eastern U.S., at taxpayers' expense. The plan would eliminate many of the wild herds that currently exist and greatly reduce the populations of the remaining herds ““ well below the levels needed for their continued survival. Salazar's plan would also mandate aggressive sterilization of wild horses on public lands, essentially “managing” the wild horses into extinction.
