Are There Mountain Lions in Idaho?

Mountain lions, also known as cougars or pumas, are a native species established throughout Idaho’s diverse ecosystems. These powerful predators play a significant role in maintaining the natural balance of wildlife populations. The mountain lion (Puma concolor) is the largest wild cat species in Idaho, with adult males typically weighing between 80 and 265 pounds. Understanding their presence and management is important for residents and visitors.

Confirmed Presence and Geographic Range

Mountain lions occupy nearly all suitable landscapes throughout Idaho. Their distribution is closely linked to the availability of primary prey, including healthy populations of mule deer and elk. They thrive in areas offering topographical cover, such as mountainous regions, rocky slopes, canyons, and dense forested lands.

The highest concentrations of mountain lions are found in the state’s more rugged and remote areas, including the central mountains and the northern Panhandle. However, their extensive home ranges, which can span 50 to 350 square miles for a male, mean they are not restricted to deep wilderness. Areas bordering human development, such as foothills and river corridors, often serve as movement pathways or hunting grounds.

While less common in the arid or agricultural southern plains, mountain lions may still be encountered along major river systems where suitable cover and prey exist.

Population Management and Conservation Status

The Idaho Department of Fish and Game (IDFG) manages the mountain lion population, classifying it as a regulated big game species. This classification, established in 1972, replaced earlier bounty systems and allows for the regulated harvest of the species. The management goal is to maintain a healthy, well-distributed population while addressing concerns like livestock depredation and human-wildlife conflict.

Hunting is the primary tool IDFG uses to manage mountain lion density. This involves established hunting seasons, the requirement of a license and tag, and specific regulations regarding the use of hounds. To protect reproductive capacity, many hunt units utilize female-specific harvest quotas, limiting the number of female lions taken in a given area.

The mountain lion population in Idaho is considered stable. The species is not listed as federally endangered or threatened, reflecting its secure status within the state.

Safety Guidelines for Living and Recreating

Encountering a mountain lion is rare, but people recreating in Idaho’s wildlands should understand conflict avoidance measures. Never run from a mountain lion, as this action can trigger the animal’s instinct to chase prey. Instead, remain calm, maintain eye contact, and slowly back away while facing the animal.

If a lion does not retreat, you should try to appear as large as possible. This can be done by raising your arms, opening a jacket, or standing on a stump. Shouting loudly and firmly can also help convince the animal that you are not prey. In the rare event of an attack, fighting back aggressively with any available object is the recommended course of action.

Reducing Attraction Near Homes

Homeowners can reduce the likelihood of attracting lions by securing potential food sources. This includes securing household garbage with tight-fitting lids and feeding pets indoors. Unsecured waste or pet food can attract the lion’s natural prey, such as raccoons or deer. Closely supervising children and small pets is also recommended, especially during dawn and dusk hours when mountain lions are most active.
