Volunteers in Central Valley remove fences to save antelope

The fences crossing the desolate Carrizo Plain are remnants of the hardscrabble homesteaders who arrived a century ago, then abandoned the arid, alkaline land to the elements.

The long stretches of fence spread across the range prevent the pronghorn from fleeing predators and seeking forage, and are a big reason why the herd has the worst survival rate in the West. Pronghorn are North America's fastest runners, but cannot jump the fences. So volunteers have taken on a cowboy's most odious ranch task, hoping to improve the odds of the herd by taking down fences. Suffering bloody scrapes and punctures, they dismantle rusty barriers and modify others to give the antelope of the Carrizo Plain National Monument a fighting chance against coyotes that vastly outnumber them. The pronghorn are part of a debate over the future of the Carrizo Plain, designated a national monument by the federal government nine years ago. A draft management plan for the park indicated some cattle grazing would be allowed to control invasive species, but the EPA and others have countered that cattle can adversely affect native species as well.
