Green Valley Farm + Mill

Join us in Sebastopol, California for a week of farming, learning and building community, with a focus on small scale diversified farming systems. This week-long farm experience is part of the Climate Farm School learning program.

About the farm

The property

Green Valley Farm + Mill is a 172-acre property located on Southern Pomo, Kashia, and Coast Miwok ancestral lands. Its footprint comprises the majority of the headwaters of Green Valley Creek, where salmon still return to spawn, and a large part of what is considered the Green Valley.  The farm is surrounded by neighbors that have lived on and stewarded this land for centuries. The current onsite community is committed to ecological stewardship, education, and vibrant, regenerative farm enterprises. It is a cooperatively owned farm with several on-farm businesses including a raw milk herdshare, a dry-farmed vineyard, a medicinal herb garden, specialty vegetable production, a forest-to-furniture business, and a children’s nature awareness program. 

Farm team

Green Valley Farm + Mill’s co-founders bring a depth of experience to all aspects of management, from the built environment to beyond organic farming. Participants will interact directly with Aubrie Maze (Farm & Land Manager), Scott Kelley (Facilities Manager) and Scott Chang-Fleeman (owner of Shao Shan Farms). Aubrie has lived on the land for 7+ years and has a background in herbal medicine and animal husbandry. Scott comes from a long line of farmers and ranchers, has also lived on the farm for over 7 years and is continuing his heritage by raising cattle and milking cows on the land.

"Climate Farm School should be required coursework for every generation.. I've learned that it doesn't matter if you work in the climate or agriculture industry; as humans, we are a part of, not apart from, the agro-ecosystem, and we owe it to ourselves and our planet to understand the complexity of our food systems."

Accomodation and other FAQs

Participants in this course will stay in the 7-bedroom farmhouse onsite (photos available here), or there is a camping option for a reduced rate. Two of the bedrooms are suites and are available for a slightly higher course price.

There is one full bathroom w/ shower in the farmhouse (downstairs), and one additional bathroom (upstairs). There are 2 outdoor showers available for participant use, and ecozoic composting toilets next to the barn.

Camping is available for a reduced course price, and campers can either bring their own tent and camping gear or request camping gear be provided by the course team (limited number of tents and sleeping set ups available onsite).

The course theme is small scale diversified farming systems. In addition to the core course content, this site will feature guest speakers and create dedicated discussion time for delving into topics related to innovative regenerative farming systems that are small scale (<500 acres), diversified, and include both animal and vegetable production.

The climate is typical of coastal Mediterranean ecosystems, with large daily temperature fluctuations, potential for intense heat in the summer, and a wet/dry season with very little or no rainfall from approximately April through October. Temperatures are often quite cool at night, so plan accordingly and bring layers!
