Animal advocates are suing the U.S. Forest Service in hopes of deterring the possible slaughter of dozens of wild horses.
The agency says it is trying to control the animal's population by rounding up the remaining wild horses in California's Modoc National Forest.
In a statement released Monday, advocates claimed the Forest Service would be reducing the wild horse population by 80% which could potentially lead to the sale of the animal for slaughter.
Advocates say this would endanger the long-term genetic viability of the remaining population.
The wild horse population in that area stands at 1,100 with the agency planning to remove about 900 of them, according to the lawsuit.
