Sharon Negri

Sharon has dedicated her life to advancing the protection, conservation and management of mountain lions and ensuring that they flourish in our natural world.

​She has worked with government and nongovernment organizations on natural resource issues since 1980. Sharon co-founded the Mountain Lion Foundation in 1986 and served as its director until 1990, after working with others to pass a California ballot initiative that banned trophy hunting of mountain lions and allocated $30 million a year for 30 years to critical wildlife habitat.

In 2024, Sharon returned to the Mountain Lion Foundation as Director of Strategic initiatives and Partnerships in order to nurture greater reach for the Foundation’s programs and partnerships in cougar conservation.

In addition to her role at Mountain Lion Foundation, Sharon continues to direct work at WildFutures, where she provides consultation to a wide array of regional, state, national, and international wildlife organizations focused on advancing protections for large carnivores.

Among Sharon’s published works are Cougar Management Guidelines (2005); Cougar Ecology and Conservation (2009), with renowned cougar biologist Maurice Hornocker; and numerous reports and papers for foundations, agencies, and conservation organizations. She produced the films The Secret Life of Mountain Lions (2016) and La vida secreta de los pumas (2017), and she co-produced the award-winning film On Nature’s Terms (2001) and a television public service announcement on cougar and bear awareness and safety.

In her spare time, she sings karaoke and DJs in Northern California, spends time with her lab mix dog, Jack, and photographs people and places.

Josh Rosenau

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.
