Mojave Desert burros

Federal authorities are looking for the culprits responsible for the deaths of more than 40 wild burros in California.

The Bureau of Land Management said the burros, which are from the Clark Mountain Herd Area in San Bernardino County, were shot and discovered dead in the Mojave Desert between Halloran Springs, Calif., and Primm, Nevada.

The animals’ carcasses have been found in various stages of decomposition since May.

“This is a mass killing of these animals,” Grace Kuhn with the American Wild Horse Campaign tells PEOPLE. “They were shot and left for dead. They are America’s treasure and they should be treated as such — instead they are being treated as trash.”

In one case, Kuhn says an officer found a group of 16 dead.

There are only 16,200 burros living in the western United States. There are 4,700 in California.

Kuhn says the 42 burros that were killed came from a herd of 120.

“They were all healthy,” she says.

The animals have been federally protected since 1971. Wild horses are also federally protected, as is the bald eagle.

“I believe it is pure hostility to eliminate the animals from the area,” she says. “They aren’t seen as the cultural icons they should be.”

Killing them is not the answer, she says.

“If there is an issue with a burro in the area, there is a way to mitigate the problem which doesn’t result in killing the animal,” she says. “You don’t have to brutally gun them down.”

The Bureau of Land Management has offered a $10,000 reward leading to an arrest and conviction in the case.
