Living with Lions is a community conservation project in the Mayacamas Mountains of Sonoma and Napa Counties.

Since 2016, Audubon Canyon Ranch’s Living with Lions has increased awareness of the behavior and movements of our local mountain lions; explored and explained factors that influence reproductive successes and failures; and prompted neighborly conversations about the role of top carnivores in healthy landscapes.

Mountain lions in the North Bay live a fragile existence

Mountain lions are top carnivores playing an important role in our North Bay ecosystem yet they live a fragile existence, moving through a mosaic of public and private lands. Audubon Canyon Ranch is studying our region’s mountain lions to identify priority habitats and key wildlife corridors and to promote ecosystem conservation throughout our region.

Rigorous science — humanely conducted

Dr. Quinton Martins, a big cat expert and principal investigator for the project, works with local veterinarians and residents to locate and humanely capture and equip lions with GPS collars. Biological measurements and samples are taken to determine their age and health, as well as to map the genetic makeup of the region and state’s lion populations.

The Living with Lions team includes conservation scientists, ACR educators, local veterinarians, geneticists, and a growing cadre of volunteers to assist in field work. Project partners include the California Department of Fish and Wildlife, California State Parks, UC Berkeley, Sonoma County Regional Parks, Sonoma County Ag + Open Space, Sonoma Land Trust, as well as residents and private land managers.

Program findings—including DNA samples, tracking data from GPS collars, and trail camera observations—are shared with the California Department of Fish and Wildlife for their statewide survey, in scientific journals, local media, community presentations, and translated into richly-designed classroom curricula developed by ACR’s educators.

Wild Neighbors Classroom Presentation and Learning Resources for Teachers and Families

Audubon Canyon Ranch’s scientists and educators teach more than 11,000 children and adults each year about conservation science and the importance of mountain lions in our ecosystem. Through an interactive Wild Neighbors classroom presentation, children are introduced to the captivating world of mountain lions and other wild creatures roaming outside our doors.

Reducing conflict between lions, humans and livestock

Research is paired with outreach to help residents implement the best methods to deter mountain lions from preying on pets and livestock, lion behavior that can result in the issuing of a ‘kill permit’ for the lion. By raising awareness about mountain lions and providing tips for co-existence, we can help safe-guard our community’s vital natural systems.

Become a citizen scientist with our trail camera project!

The Living with Lions trail camera project uses cameras placed on private properties to collect visual data on mountain lions in Sonoma and Napa counties, as well as add to our region’s understanding of overall wildlife diversity. LEARN MORE >
