About Tuleyome

Tuleyome was founded in 2002 as a volunteer advocacy-oriented nonprofit conservation organization. Our mission is: "Tuleyome engages in advocacy and active stewardship with diverse communities to conserve, enhance, restore, and enjoy the lands in the region."

At Tuleyome we “live” our mission every day: we preserve and restore wild habitat, we build and repair trails, we educate the public about local conservation and environmental issues, we engage young people through our youth program, we demonstrate a good “land stewardship” ethic by maintaining the easements and properties we own under the scope of our land trust component, and we run campaigns that have a long lasting positive effect on the region.

It is our hope that our work will inspire members of the public to protect, restore, and enjoy the natural landscape in the Northern Inner Coast Range.

Andrew Fulks, President

Andrew, a licensed landscape architect, is presently the assistant director of UC Davis arboretum and public garden, as well as being the president of Tuleyome’s Board of Directors. He has been a constant advocate for appreciation of the Putah and Cache Creek watersheds in the central valley of California. To draw attention to the region, he founded Yolohiker.org, a local trails advocacy, hiking, and outings webpage and co-founded the Capay Valley Hiking Club, an ad-hoc group of hikers that meet twice a month to hike in the watershed. In 2002 Andrew co-founded Tuleyome. In 2015, Andrew was honored with a national “Trails Worker Award” at the 2015 American Trails Association’s award symposium in Portland, Oregon for his work on trails in the Central Valley, especially the marathon-level Berryessa Peak Trail. Email: afulks@tuleyome.org.

Victoria Brandon, Vice-President

Victoria Brandon has lived in Lake County, exploring the local scene and hiking the local trails, since 1981. Her activist career began shortly after the 2000 election when she began writing letters to politicians and others on behalf of various environmental causes, primarily at the behest of the Sierra Club. She was elected to the Club's Redwood Chapter Lake Group executive committee in 2004, and was Group Chair for five years, mobilizing support for the Wilderness Bill, the Cache Creek Wild & Scenic campaign, Berryessa Snow Mountain National Monument campaign, and numerous other local and regional conservation issues. A member of the Redwood Chapter executive committee and Chapter political chair since 2006, she has been Chapter Chair since 2013 and is now co-chair of the Sierra California political committee and a member of the Club's national political team. As well as the Tuleyome Board, she also serves on the Board of the East Lake Resource Conservation District. State Senator Pat Wiggins named her Senate District 2 Woman of the Year in 2008.

Steve Drown, Treasurer

Steve has been involved with environmental issues since his youth in Boy Scouts.  He pursued his interest in college (degree in Environmental Geography), law school (environmental law at University of Oregon), and professionally, when he served as environmental attorney for 13 years.  Although his professional focus broadened in the past 20 years, when he served as UC Davis Chief Campus Counsel and Senior Counsel for the University of California, his service to Tuleyome has offered him the opportunity to return to his initial interest in youth engagement in the natural environment.  Steve, on behalf of Tuleyome, has developed the “Boot Bank,” which offers free high quality hiking boots to area youth throughout their growing years (up to 18) to encourage them to engage in, and value, their surrounding natural environment.  Hopefully, these youth will become the next generation of conservationists.
