Asked by an anonymous Tumblr user.
The U.S. Department of the Interior’s Bureau of Land Management (BLM) protects, manages, and controls wild horses and burros under the authority of the Wild Free-Roaming Horses and Burros Act of 1971. The Act declares wild horses and burros to be “living symbols of the historic and pioneer spirit of the West.”
BLM protects the health and welfare of the wild horse and burro population and makes sure it is consistent with the land’s capacity to support them. They also offer an adoption program and have other ways for volunteers to get involved.
