Facing the complex problem of too many wild horses

"Wild horses couldn't keep me away" is a saying, but in real life, plenty of people would like to keep wild horses--otherwise known as mustangs--further away. "The number of horses—along with all the cattle grazing on public lands—has led to a calamity on the rangeland. Wild horses are reproducing at unsustainable rates; between 2007 and 2021, their numbers more than tripled," reports Heather Hansman of Sierra magazine. "In their search for forage, wild horses are tearing up high-desert vegetation, degrading riparian areas, and trampling fragile native plants. . . . As climate change makes the West hotter and drier, the animals are struggling to find water too. In some places, horses have been known to die of starvation and dehydration."

Solutions have proved difficult to find between land stakeholders and horse advocates. Hansman explains, "Roundups for slaughter are off the table—as a matter of humane treatment and U.S. law. Birth-control programs have shown promise, but they are difficult to carry out and are opposed by some horse advocates who express worries about horse health, genetic diversity, and unintentional sterilization. Some horse advocates complain that the Bureau of Land Management's annual roundups can be inhumane."

"One thing that horse people and ecologists agree on is that this situation is a mess. The system is so broken that Congress has called it a 'national crisis,'" Hansman writes. "... the magic and myth of the mustangs seem to collide with the realities of landscape management, policy tussles, and laws that haven't been meaningfully updated since the 1970s."

What does everyone want? "Healthy horses on healthy landscapes is what they say," Hansman reports. "But how can we reach that goal? Especially in the era of climate chaos, especially with an animal that sparks such intense emotions. . . .The story of wild horses is also the story of water and space and the ideal of wildness—the hope that the American West is still big enough for everyone who wants a slice and that last century's laws are adequate for 21st-century complexities. But on the range today, there is not enough to go around, and our ideas about wildness must be constrained by reality. How can we know what the reality is when we've been operating on stories for so long?"
