The mission of the Mountain Lion Foundation is to ensure that America’s lion survives and flourishes in the wild.

Our Vision

The Mountain Lion Foundation envisions a world where lions and people coexist, where sustainability includes the persistence of the human ecosystem in harmony with viable wildlife communities, and where wildlands are nurtured and not subdued.

America’s lion is a marvel of adaptation, descending from Asian felids of 11 million years ago. For millennia, Puma concolor inhabited forests, deserts, mountains, islands and bottomlands of the New World’s two massive continents. Our vision is that the ecological miscues of the Anthropocene Age abate, allowing restoration of lions throughout these diverse habitats.

Our vision requires humans to respect and trust, not fear, lions in proximity.

We live in a time of climate stress, a fearsome pace of extinctions and a planetary crisis. If humankind can reverse the lion’s decline, there is hope.

Our Cornerstones

America’s Lion – Mountain lions are a keystone species indispensable to ecological communities. Although development has compromised lions’ range throughout the Americas, given protection, including restoration of habitat, lions will thrive.

Communication – The Mountain Lion Foundation strives for consensus that lions deserve protection. We ensure the continued existence of lions and the wild places on which they rely by securing their protection through education, outreach, and advocacy.

Science –  The Mountain Lion Foundation formulates conservation policy and programs to benefit lions and lion habitat while maintaining an independent and mutually beneficial relationship with the research and scientific communities.

Corridors – Lions require corridors to move about their territories and for their young to disperse. Because development has fragmented lion habitat, we support protecting critical habitat, corridors and freeway crossings for lions and other wildlife.

Coexistence – We promote effective preventative measures to resolve perceived human-lion conflicts. We urge the public and relevant agencies to fully appreciate lions as a vital and indispensable apex species deserving preservation rather than exploitation.

Our History



  • Mountain Lion Foundation and their co-petitioners, Center for Biological Diversity, Sierra Club and Cougar Connection, reach an agreement in the Temecula Altair lawsuit which protects a critical wildlife corridor for mountain lions and other wildlife.
  • California governor, Gavin Newsom, signs Assembly Bill 1788 into law, which bans the use of first- and second-generation anticoagulant rodenticides (one of the leading causes of death for mountain lions, bobcats and other wildlife) in the state.
  • Mountain Lion Foundation supports Washington Department of Fish & Wildlife in banning wildlife hunting contests to help prevent “spree-killing contests”, such as coyote derbies that have no bag limits.
  • Mountain Lion Foundation urges Nebraska Game and Parks to end mountain lion hunting in the state, as the population dips below 50 individuals.
  • CESA Petition advanced to candidacy
  • In a welcome move to protect California’s mountain lions, the California Department of Fish and Wildlife (CDFW) expanded the boundary of the three strikes mountain lion depredation policy statewide. The policy requires landowners that have had pets or livestock attacked to first try non-lethal means to deter mountain lions before a lethal permit will be issued.
  • The Washington Fish and Wildlife Commission voted to ban wildlife-killing contests, making it the seventh state to enact such a measure.


  • Carmel Area State Parks in CA added over 1600 acres of protected land. Land purchased with Prop. 117 funding, championed by MLF in 1990 (Habitat Conservation Fund).
  • Mountain Lion Foundation is proud to partner with CDFW, and happy to see Gov Newsom announce that his new budget proposes $7 million in new funding to enhance human/wildlife conflict responses.
  • Roxy’s Law bans traps, snares, and poisons on public lands in NM, Sen Bill 32
  • AZ Game and Fish Commission banned the use of trail cameras for aiding the take of wildlife effective 1-1-2022
  • FL lawmakers pass bill funding efforts to expand state’s wildlife corridors

  • MLF and its co-plaintiffs lose its appeal against the Oregon Wildlife Services, and the USDA.
  • MLF rallies its California-based membership to object to a plan by the California Department of Fish and Game to close some of its wildlife refuges.
  • MLF launches On Air, a broadcast project that conducts audio interviews with mountain lion experts.
  • MLF participates in a community meeting after a lion is shot by police near the UC Berkeley campus and the public is outraged by the lack of non-lethal management techniques. MLF’s outreach efforts encourage Californians to write letters to law enforcement agencies demanding a change from a “shoot first” attitude, and later that summer the Morgan Hill (California) Police Department uses pepper-balls to scare away a lion from town, and a game warden in San Bernardino county humanely tranquilizes and relocates a dispersing juvenile.
  • MLF is recognized by the California State Senate for its contribution in passing Proposition 117 twenty years earlier.
  • Thirty-four groups from 13 states joined MLF in an ad hoc coalition to celebrate and promote the American lion for a period of 117 days–June 7 through September 30, 2010. MLF’s Celebrating the American Lion Campaign’s goal was to raise the national awareness of the plight facing lions in America today and to showcase the advocacy and public education work of the coalition’s partner organizations.
  • MLF starts its Lion Partners program where the Foundation provides advice and assistance to small volunteer mountain lion advocacy groups.
  • MLF joins the Twitter network as MtnLionFdn to update members instantly on the latest cougar news, events, and action alerts.


  • MLF started off the year by posting a special 8-minute video detailing the basic biology and behavior of mountain lions on YouTube with links from the MLF website. A DVD of the video was also produced for distribution to small local conservation groups and educational institutions for use in public presentations without the need of an actual MLF presenter.
  • In May, MLF tried something new by placing a “Stop the Killing. NOW!” on-line petition. In this petition we called for: Banning the recreational hunting of lions on all federally owned or controlled lands. Halting the use of federal funds or agencies to conduct lion eradication or removal programs. And, demanding that the Governors of states with existing lion hunting policies emplace a moratorium on all hunts until that state’s lion population model and management plans have undergone a rigorous scientific peer-review process.
  • MLF’s web-based activities centered on reinventing its website with a new, visually appealing, and user-friendly layout.
  • MLF premiers its new “Where do we go from here?” poster and “American Lion brochure at a special gala event at the San Francisco Academy of Sciences.
  • MLF partners with the St. Luis, Missouri Audubon Society to help inform that state’s citizenry about their lions (or the official lack of them) by developing two special Missouri specific educational brochures.
  • MLF creates a special Washington state specific informational brochure.
  • MLF joins with the Washington chapter of HSUS, PAWs, and a small collection of unaffiliated cougar activists to try and stop WAC 232-12-243. This particular administrative rule change would (in direct violation of Initiative 655) allow hunters to use hounds to hunt cougars in Washington for recreational purposes.
  • MLF drafts and helps pass California Senate Bill 769. SB 769 is an amendment to Proposition 117 to allow the use of post-1990 lion carcasses and body parts for educational purposes.


  • MLF continues an effort started in April of 2011 to reauthorize mountain lion research in California. The final outcome of this effort is the passage of Assembly Bill 1784, an amendment to Proposition 117 written and promoted by MLF.
  • MLF helps raise the public’s awareness to the actions of California Fish and Game Commission President Dan Richards after he kills a mountain lion on a legal hunt in Idaho and then brags about it by posting a photograph of him lifting his dead trophy. In the end we were unable to get Mr. Richards removed from the commission, but our actions, coupled with those of other conservation organizations, have resulted in the introduction of several legislative bills aimed at reforming the Commission.
  • MLF starts a campaign to change the way the California Department of Fish and Game handles mountain lions that are listed as an imminent threat to the public’s safety, and investigates the killings of mountain lions in Sunland and Santa Monica California.

  • In an unprecedented move, the U.S. Fish and Wildlife Service  announced that it is giving up its watchdog role over Florida’s endangered species in order to “streamline” the permitting process for development projects that may hurt rare plants and animals. This means that the continued existence of several threatened species such as the Florida Panther are now in the hands of the State of Florida; an entity which in the past has more often sided with developers.
  • According to Commissioner Ron Bergeron of the Florida Fish and Wildlife Conservation, too much water is turning Florida’s “River of Grass” into “Lake Everglades” and that could have a devastating impact on the Everglades and its inhabitants including the Florida panther.
  • The Missouri Department of Conservation  has announced the 40th confirmed sighting of a mountain lion in that state since 1994.
  • California lion protection legislation passed today when California Governor Brown signed Senate Bill 132. This is a first of its kind piece of legislation built on decades of scientific knowledge to define what exactly “imminent threat to public health and safety” means in regards to mountain lions. The bill requires the use of nonlethal procedures for dealing with those lions that come into contact with humans, yet do not meet the threshold of imminent threat.

Projected to cost $33 million to $38 million, the 165-foot-wide, 200-foot-long overpass, complete with drought-tolerant vegetation, near Liberty Canyon Road would connect the Santa Monica Mountains on the south with the Simi Hills and Santa Susana Mountains.


  • Colorado’s first wildlife bridge is proving to be a huge success. Saving the lives of both wildlife and motorists, the wildlife overpass on Highway 9 in Grand County was designed to reduce collisions on one of the most dangerous stretches of road in the state. The multi-million dollar project is the first of its kind in Colorado.
