Mountain lion social organization in the Idaho Primitive Area

Building on long-term tracking of marked mountain lions, this study described how pumas organize their use of space through a land-tenure system maintained largely by mutual avoidance. Resident adults occupied home ranges that they advertised with scrapes and scent, with males ranging over larger areas overlapping several females, and individuals timing their movements to avoid one another rather than defending rigid boundaries through direct conflict. The work showed how a solitary, wide-ranging cat regulates its own density and spacing, with social tolerance and avoidance structuring the population. It became a classic account of solitary felid social systems in temperate mountains and complemented the predation studies from the same project. For enthusiasts it explains how pumas, despite living alone across vast ranges, maintain an ordered society through signals and avoidance rather than the overt territoriality of group-living cats.
