Mountain Lions 101

Understanding one of North America's most remarkable carnivores.

Mountain lions once ranged across nearly all of the Americas. Habitat loss, fragmentation, and fear-driven policies are putting their future at risk.

They play a critical role across their range. As apex predators, they help regulate deer populations, contribute to healthy and resilient ecosystems, and support biodiversity across diverse landscapes.

Protecting mountain lions is about more than protecting a single species, it means protecting the wild heritage of America. It is about advancing practical coexistence solutions that keep communities safe, preserving biodiversity, and ensuring future generations inherit healthy, connected landscapes.

Some Facts About Mountain Lions

Fast facts about one of the Americas' most remarkable predators.

Scientific Name

Puma concolor

Range

Found from Yukon, Canada to Patagonia in Chile, as well as populations in 16 U.S. states.

Lifestyle

Solitary but not isolated, can be active any time of day. Human activity impacts cougar activity – they’re more active during the day where hunting or recreation pressure is less.

Other Names

Cougar, puma, panther, catamount, painter, and mountain lion all refer to the same animal.

Diet

Obligate carnivores that hunt a variety of prey, but primarily ungulates.

Ecological Role

A keystone species helping shape healthy, connected landscapes.

Life as a Mountain Lion

Solitary, adaptable, and shaped by the landscapes they call home.

Home Range & Movement

Mountain lions use large home ranges and depend on connected habitat to find food, mates, and safe places to live.

Hunting

They are stalk and ambush predators with powerful bodies, sharp senses, and specialized teeth and claws.

Family Life

After a three month gestation period, females raise kittens on their own, teaching them how to survive, until the young disperse at around 15 months of age. 

Adaptability

Mountain lions can live in forests, deserts, mountains, wetlands, and other landscapes when habitat and prey are available.

Where the Lion Lives

Adaptable enough to thrive across deserts, forests, mountains, and grasslands.

Mountain lions are among the most adaptable mammals in the Americas. They can be found in deserts, forests, mountains, wetlands, and grasslands wherever suitable habitat and prey are available.

Once ranging across nearly all of North and South America, mountain lions now occupy a smaller and increasingly fragmented range in many regions. Their long-term survival depends on connected landscapes that allow them to move, find mates, and maintain healthy populations.

Historic Range

Once found across nearly all of the Americas, mountain lions once thrived in an extraordinary diversity of habitats, from eastern hardwood forests to western mountains, deserts, and temperate rainforests.

Current Range

Established populations remain broadly distributed across the western United States, while the endangered Florida panther persists as the last surviving breeding population in the eastern U.S.

Connected Habitat

Mountain lions depend on connected landscapes that allow them to disperse, find mates, and maintain healthy populations.

Why Mountain Lions Matter

More than a carnivore.

Mountain lions play an important role in the ecosystems they inhabit. As apex predators, they influence relationships between wildlife, vegetation, and the landscapes we all depend on.

Their presence affects far more than their prey, contributing to ecological processes that help support biodiversity, habitat health, and resilient landscapes.

Ecological Relationships

Part of a larger ecological story.

Mountain lions can live in forests, deserts, mountains, wetlands, and other landscapes when habitat and prey are available.

Biodiversity

Supporting diverse and resilient ecosystems.

Mountain lions require large, connected habitat to survive. As an umbrella species, conserving those landscapes for lions means benefiting countless other species and ecological processes.

Connected Landscapes

Protecting lions means protecting habitat.

Mountain lions require large, connected territories to survive. Conserving those landscapes benefits countless other species and ecological processes.

Challenges Facing Mountain Lions

A species adapted to survive, but facing growing pressures.

Mountain lions are remarkably adaptable, but adaptation has limits. Across their range, habitat loss, fragmentation, vehicle collisions, and conflict with people continue to create challenges for mountain lion populations.

Understanding these pressures helps us better understand why conservation, coexistence, and connected landscapes matter.

Habitat Loss

Less space to live and roam.

As communities expand and wild lands are converted to other uses, mountain lions lose access to the habitat they need to survive.

Habitat Fragmentation

Barriers can isolate populations.

Roads, development, and other infrastructure can divide habitat, making it more difficult for mountain lions to move, find mates, and maintain genetically healthy populations.

Vehicle Collisions

Roadways are a growing threat.

Many mountain lions are killed while attempting to cross highways and roads that intersect important movement corridors.

Conflict with People

Most conflicts can be prevented.

When mountain lions, people, pets, and livestock share the same landscapes, conflicts can occur. Education and practical coexistence measures help reduce risk and improve outcomes for both people and wildlife.
