The Rocky Mountain Elk Foundation supports the content of this video, namely that wild horse/burro numbers by far exceed objective and have a detrimental impact on rangeland ecosystems as well as native wildlife habitat.
Specifically, wild horses and burros are managed by federal law and are only authorized to be on Bureau of Land Management and U.S. Forest Service Lands. The BLM maintains horses and burros should be managed to support 27,000 individual animals, yet as of March 1, 2018, there were more than 82,000 horses alone on BLM land and more than 10,000 animals on USFS land.
Improved management actions are needed to protect public rangeland.
