The Bureau of Land Management also plans on treating more wild horses and burros with fertility control treatments than it ever has before
The federal government plans to capture and relocate more wild horses and burros on federal lands this year than it ever has before.
Earlier this month, the agency announced it would gather at least 22,000 wild horses and burros from overpopulated herds and relocate 19,000 “excess” animals. In addition, the agency plans on treating 2,300 of the animals with “various forms of fertility control” and releasing them back onto public lands by the end of September.
If the agency is successful, this will be the most burros and wild horses it has ever captured or treated with a form of “fertility control” in a single year, marking around a 40 percent increase from last year’s capture numbers and almost double the number of animals given a fertility treatment.
There are several forms of fertility control that the agency uses on wild horses and burros, with the most common being a vaccine called Porcine Zone Pellucida, a nonhormonal treatment that prevents females from getting pregnant for one to two years, according to the BLM.
But the agency also inserts IUD’s into mares, increasingly using another longer-lasting hormonal vaccine called GonaCon-Equine, which conservationists warn can change the horses behavior and disrupt herd dynamics.
Since the 1970s, the Bureau of Land Management (BLM) has controlled the country’s wild horse and burro populations by gathering, relocating and administering fertility treatments to thousands of the animals every year.
