By law, in a compromise with the Parks System, the number of wild horses allowed was capped at 50. Their numbers are monitored by the Wild Horse League and any horses removed are adopted out.
Pasture lands have been cleared and natural grasses planted for the horses in a joint effort of the U.S. Forestry Service and the National Parks Service.
Though often not being able to be seen the wild horses are a major tourism draw for Shannon County and they are much loved by the locals.
