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 has a vision of 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



  • MLF 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.
  • MLF 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.
  • MLF 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.




  • 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.
  • The US Army Corp of Engineers recently posted a photograph of a mountain lion taken at night on a trail camera placed near the Oahe Dam in South Dakota. This structure is located on the Missouri River just north of the state capital of Pierre.
  • The Iowa Department of Natural Resources  has confirmed a picture taken by a trail camera in Madison County is that of a mountain lion. The photo was taken on a farm about 10 miles north of Winterset, in rural Madison County, Iowa.


  • Last year, National Geographic put a public face to Southern California’s lion population when it photographed P-22 walking in front of the Hollywood sign at night. At that time, the animal was majestic looking and in apparent good health. However, it was announced yesterday that National Park Service lion researchers discovered in March that P-22 is now sick with mange, a parasitic disease of the hair and skin which may be the result of rodenticide poisoning.
  • Illinois Senate Bill 3049 passes placing Gray wolves, American black bears, and mountain lions on Illinois’ protected species list, and eliminates the current practice of allowing people to shoot them on sight with no questions asked.
  • The Wisconsin Department of Natural Resources announced that it has confirmed two mountain lion sightings taken from trail camera photographs in Lincoln and Marinette counties. Coupled with the lion sighting in Bayfield County last January this makes the third confirmed report of mountain lions in the state of Wisconsin during 2014.
  • For the first time in almost two years, the Kansas Department of Wildlife, Parks and Tourism  has verified the presence of a mountain lion in that state. The sighting resulted from a trail camera photograph taken in Labette County, located in the Southeast corner of Kansas.

  • An Iowan’s fight to protect mountain lions is thwarted by obstinate legislator
  • Even though it’s illegal to trap mountain lions in Montana, 48 lions have been captured in traps set for other animals over the past two years. Of those lions captured, 26 died and at least six suffered some form of damage to their paws but were released along with the non-injured lions.
  • The Arkansas Game and Fish Commission announced yesterday that the mountain lion killed by a deer hunter in Bradley County last November originated in the Black Hills region of South Dakota; almost 1,200 miles away.
  • The Kentucky Department of Fish and Wildlife (KDFW) has ended its eight month investigation into the origin and history of the first mountain lion to return to Kentucky since the species was extirpated in that state more than 150 years ago.
  • Earlier this week, the Mountains Recreation and Conservation Authority released a long-awaited study by Caltrans concluding that building the nation’s largest wildlife “bridge” over the 101 Freeway in Agoura Hills was feasible. 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.

Josh Rosenau, BA, ABD

Conservation Advocate - Region I
916-442-2666 ext. 107

Josh is a mammalogist who has worked to protect wild salmon and orcas, defend science educators against political pressure, and led efforts to push candidates to explain how science would inform them in Congress and the Oval Office. After graduating with a bachelors in Biology from the University of Chicago, he began a doctoral program at the University of Kansas, based in the Museum of Natural History. During his doctoral studies in Kansas, he changed directions from ecology and evolutionary biology to focus on science communication and science policy. With coalitions of clergy leaders, scientists, and parents, he led campaigns to defuse conflicts over the science lessons on topics like climate change and evolution. At the Mountain Lion Foundation, he is returning his focus to mammals, connecting and informing communities about their cougar neighbors, and helping to turn conversations from conflict to cooperation as we strive to Save America’s Lion.

Outside of work, Josh loves to explore wild places with his wife and two children. A lifelong hiker and birder, he has led Grand Canyon rafting trips and hikes, and since moving to Washington, has taken up kayaking and fly fishing.

As Conservation Advocate in Region I, Josh oversees our outreach and advocacy in California, Idaho, Montana, Oregon, Washington and Wyoming

Board of Directors

Bob McCoy

Issaquah, Washington

Bob started researching Puma concolor and joined the Mountain Lion Foundation in 2009. The following year, he testified against the Washington Cougar Hounding Pilot Program, formed the Washington Cougar Coalition (WA Cougar), and became the Foundation’s Washington State Field Representative. Since then, he and volunteers have repeatedly stopped bills that would have harmed cougars. In 2013, Bob represented the Foundation on a panel at the 13th Mountain Lion Workshops in Utah. In 2015, Bob spurred WA Cougar to appeal the Washington Commission’s failure to follow proper procedure in setting cougar hunting guidelines. Led by HSUS lawyers, we achieved the first overturn of a citizen commission ruling by a governor in state history. The Commission returned in 2016 to the prior hunting quota. Bob is now working to keep the state from taking measures against cougars in retaliation for the successful return of wolves to Washington. Bob McCoy became a member of the Board of Directors in July 2016.

Fauna Tomlinson

Lake Tahoe, California

For 30 years I’ve been fortunate to call Tahoe my home along with my husband and our two talented adult kids. I’m in real estate for a living but my passion is the big cats of the world. I started with the Indian Bengal tiger, the Snow Leopard with many trips to India and Nepal. It’s a privilege to work on native lion and coyote issues. Being on the board of Mountain Lion Foundation is an honor for me, giving me a chance to make a difference on behalf of America’s lion in a new and exciting way. Keeping it wild!
