Start by asking “Why?”
Why are AMLs small relative to the available resources? Why are HMAs and WHTs managed primarily for livestock? Why do the RMPs assign most of the food to cattle and sheep in areas set aside for horses and burros?
These questions will take you upstream in the management process, to policies, regulations and statutes, as well as the attitudes and beliefs of those who write them.
Almost half of the land designated in 1971 is now managed exclusively for livestock.
The original statute ordered the secretaries of Interior and Agriculture to work with state wildlife agencies to protect wildlife in those areas, especially endangered species.
There was no provision for livestock.
Roundups, darting programs, sterilization, sex ratio skewing, adoptions, training and slaughter are symptoms of the problem, not causes.
Who benefits from these things?
Wild horse advocacy takes a giant leap forward when it learns how to distinguish between cause and effect.
Today, it has a downstream focus and is dominated by frauds, reflected in the following image, so it can never bring improvements for the horses, only prolong their misery.
