The 19,235 AUMs in the grazing permits provide roughly $1.9 million in benefits to local economies. That’s about $100 per AUM per year in economic activity.
Now we can put a price tag on wild horses.
The Onaqui AML is not 210, but 210 × 12 × 100 = $252,000 per year in lost economic value.
The pre-gather population of 500 represents 500 × 12 × 100 = $600,000 per year in lost economic activity.
The answer is obvious: Remove the horses and give their food to the ranchers.
This is an area where the advocates can unite with the cattlemen in their desire to get rid of wild horses.
