We are appalled.
On one level, the vote to allow wild-horse killing is easy to understand. The Bureau of Land Management (BLM) scheme for managing protected wild horses and burros has never worked well, and has collapsed completely in the last 15 years.
Rounding up wild horses with helicopters and removing most of them for adoption is a strategy whose success depends on the whims of the horse adoption market, and works against wild horse reproductive biology. Adoptions have not kept up with removals, and removals have not kept up with natural growth of wild horse populations on the range.
But if other issues conspire to divert public attention from horse-killing, the 20 percent annual growth rate shown by wild horse populations on public lands would refill BLM’s holding facilities to current levels in a mere three years. The killing strategy is no more sustainable than the roundup and adopt strategy.
The wild horse challenge cannot be solved unless wild horse reproduction is managed on the range. Less than a mile from where the House Appropriations Committee debated killing wild horses, experts from all over the world participated in the eighth International Conference in Wildlife Fertility Control. There, researchers from Cummings School of Veterinary Medicine at Tufts University, The Humane Society of the United States and the University of Toledo presented data from field trials showing that two doses of a contraceptive vaccine (known as PZP) delivered several years apart can block wild horse pregnancies for five years or longer. The vaccine costs a few hundred dollars for the first dose, but only $25 for the second.
Another research group from Colorado State University, the National Park Service and USDA’s National Wildlife Research Center showed remarkably similar data from wild horse field trials with a different contraceptive vaccine (known as GonaCon). These vaccines, and the data describing their safety and effectiveness, are both well known to the BLM, which has been funding such research for decades. Side effects are minimal, mostly consisting of short-term reactions at the injection site experienced by some horses.
Cedar Mountains is a tough place to work, covering 280 rugged square miles, nearly 60 percent of which is wilderness off-limits to vehicles. If BLM can do it there, they can do it nearly everywhere.
Instead of funding horse killing, Congress should insist that management by fertility control gets done, and provide the BLM with the cash to do it.
Bill Richardson has served as a U.S. congressman (1982-1996), U. S. ambassador to the United Nations (1997-1998), secretary of Energy (1998-2000) and governor of New Mexico (2003-2011). With actor and conservationist Robert Redford, he started the Foundation to Preserve New Mexico Wildlife to protect wild horses and provide alternatives to horse slaughter.
