Mountain lions once roamed nearly all of the United States. They were prized by hunters and despised by farmers and ranchers who suffered livestock losses at their hands. Subsequently, by the dawn of the 20th century, mountain lions were eliminated from nearly all of their range in the Midwest and Eastern U.S.—though the endangered Florida panther survives. Today, whitetail deer populations have rebounded over much of the mountain lion's former range and a few animals have appeared in more eastern states such as Missouri and Arkansas. Some biologists believe that these big cats could eventually recolonise much of their Midwest and Eastern range, if human presence in these area's permits them to do so.
As a predator of whitetail deer, mule deer, elk, bighorn sheep, and livestock, many hunters and farmers still consider them to be a pest. However, when prey survival is not a concern, they are considered as a trophy game species; in most western U.S. states and Canadian provinces, populations are considered sustainable enough to allow managed sport hunting. Under both conditions, the ability to estimate and track changes in local populations is now more than ever crucial to the survival of the species.
