The BLM has established Herd Management Areas to determine where and how many animals will be sustained as free-roaming populations. Some populations of free-roaming horses and burros remain protected under the Act, but others have disappeared from places where there were once established populations. A few hundred free-roaming horses survive in Alberta and British Columbia. The BLM considers roughly 26,000 individuals a manageable number, but the feral mustang population in February 2010 was 33,700 horses and 4,700 burros. More than half of all mustangs in North America are found in Nevada (which features the horses on its State Quarter), with other significant populations in California, Oregon, Utah, Montana, and Wyoming. Another 34,000 horses are in holding facilities.
