How are wild horse populations controlled?
BLM rounds up excess wild horses using a helicopter and a crew of mounted wranglers. This is done on the average of once every 3 years in each herd area, and has proven to be a very effective and humane method of control. However, roundups are costly if they have to be done often and the law dictates that management be to the minimum level possible. Some fear that the roundups are harmful to the horses. For these reasons, BLM allows the horse populations to fluctuate so the number of roundups any one herd is subject to is minimized.
