Inspired by the power of soil to restore a stable climate, we formed in May 2015. We value new voices, ideas, and skills that will help further our cause. We meet monthly near the Bart Station in Fremont.

Steering Committee

Anne Bishop, co-founder of the Soils Committee, worked as a news reporter and editor in Silicon Valley for 11 years. Since 2000, she has copyedited humanities texts. Growing up, Annie spent more time outdoors than in—whether gardening, walking, camping, or backpacking in California and beyond. This formed a deep appreciation of and concern for protecting our environment. A long-time environmental activist, Annie appreciates the practicality and logic of restoring soil health to mitigate or even reverse climate change.

Anne Stauffer, co-founder of the Soils Committee, has worked as a medical and scientific writer for 20 years. She has been an environmental activist within the Loma Prieta Chapter of Sierra Club for many years and is co-organizer of the San Jose Urban Farmers Cooperative Meetup group. Anne believes that an increased awareness of our natural world will continue to lead to protection of our ecosystems, including the abundant life within soil, and ultimately to reduced CO2 levels in Earth’s atmosphere, and a stabilized climate.

Bill Buchholz is a retired architect with over 40 years’ experience in the building industry. He is an advocate for sustainable building practices and forestry practices. Bill is a lifetime member of the Sierra Club, a member of the Loma Prieta Chapter Soils Committee and Forest Protection Committee, and the Club's National Forest Certification and Green Building team. He sees growing momentum and progress in addressing climate change at all levels and is optimistic about our future.
