AMLs are small because most of the forage in wild horse areas has been assigned to privately owned livestock.
Roundups enforce those assignments.
If you shift the resources back to the horses, the AMLs are much higher. They represent the number of animals the areas could support if they were managed principally for wild horses, as specified in the statute. Western Horse Watchers calls them True AMLs.
The ranchers want to get rid of the horses so they can enjoy more of what their allotments have to offer.
Although the advocates protest the roundups, they, like the ranchers, want to see wild horse numbers go down, as a result of their fertility control programs, not helicopters.
They never contest the land-use plans and resource allocations arising therefrom.
They are in business to sell PZP. You see their influence when state and local officials call for humane management of these animals.
Instead of crashing the horses into pipe panels, stalk them with clipboards and darting rifles, drive birth rates to zero, and let the herds off.
There are few if any voices speaking in their defense.
Welcome to the love triangle on America’s public lands. It’s a big club but hopefully you’re not in it.
