Science & Knowledge

We begin with truth. In a landscape where fear and misinformation too often shape wildlife decisions, we replace assumption with evidence. Through research, field experience, and trusted expertise, we deepen understanding of how mountain lions live, move, and sustain balance in the ecosystems they shape. By turning science into clarity, we help communities and leaders make decisions grounded in facts—not fear.


Policy & Advocacy

Science matters most when it shapes the rules. We translate knowledge into durable protection—advancing policies that safeguard habitat, reconnect fragmented landscapes, and reform outdated lethal practices. The decisions made in statehouses and agencies determine whether mountain lions remain wild. We work to ensure those decisions reflect ecological reality and long-term responsibility.


People & Coexistence

Mountain lions endure where people are equipped to live alongside them. We provide practical, non-lethal solutions that reduce conflict and build confidence—from rural ranchlands to expanding communities at the wildland edge. When people have tools that work, fear gives way to understanding, and coexistence becomes possible.


Organizational Strength

Lasting protection requires more than passion—it requires strength and steadiness. We invest in expertise, partnerships, and national reach so our work endures across decades, not just moments. By building resilient systems, we ensure that the protection of America’s lion is not temporary, but lasting.

A keystone species essential to healthy ecosystems

 

Mountain lions are keystone species. Their presence helps balance ecosystems, supports biodiversity, and keeps wild places healthy.

By naturally regulating prey populations, mountain lions play a critical role in maintaining resilient landscapes — from forests and grasslands to watersheds that people rely on every day.

When mountain lions thrive, ecosystems function more effectively, wildlife communities are more stable, and landscapes are better able to adapt to change. Protecting mountain lions isn’t just about one species — it’s about the health of the places we all depend on.

Rooted in science, shaped by coexistence

 

Founded in 1986, the Mountain Lion Foundation emerged at a time when mountain lions were widely misunderstood and routinely targeted through fear-driven policies.

From the beginning, our work has focused on replacing myth with knowledge — grounding decisions about wildlife in science, ethics, and a commitment to coexistence. Over the decades, that approach has helped shift how mountain lions are studied, discussed, and protected across the country.

Today, the challenges facing mountain lions are more complex than ever — from habitat loss and fragmentation to increasing human–wildlife conflict. Our work continues to evolve, guided by the same core belief that has defined the Foundation since its earliest days: protecting mountain lions means protecting the integrity of the landscapes we all share.

Focused where the need is greatest

 

Mountain lions range across much of the United States, and so does our work. We focus our efforts in regions where mountain lions face the greatest threats — while supporting coexistence and conservation nationwide.

Our approach balances place-based action with broader national impact. By working across landscapes, jurisdictions, and communities, we help ensure that conservation decisions reflect both local realities and long-term ecological needs.

From critical habitat and connectivity corridors to policy and public education, our work is shaped by where it can make the most difference — for mountain lions, ecosystems, and the people who share these places.

Accountability at the core of our work

 

The Mountain Lion Foundation is a national nonprofit organization committed to transparency, integrity, and responsible stewardship of the resources entrusted to us.

Our work is guided by science, informed by experienced leadership, and strengthened through partnerships with researchers, conservation professionals, and communities. We believe trust is built through openness — by sharing how we operate, how decisions are made, and how support is used to advance our mission.

As a 501(c)(3) nonprofit, we are accountable to our supporters, our partners, and the public — and we take that responsibility seriously in everything we do.
