Since 1990, we’ve worked to increase appreciation and stewardship of Sonoma Valley’s natural heritage and create measurable benefits in areas of land, water, climate change and biodiversity. Supporting our work enables us to move us all towards a better future.

Who We Are

Sonoma Ecology Center works to address challenges related to water supply and quality, open space, rural character, biodiversity, energy, climate change, and a better quality of life for all residents.


We envision a future where people, land, water, and wildlife thrive.


Our mission is to work with our community to identify and lead actions that achieve and sustain ecological health in Sonoma Valley.

How can people, land, water, and wildlife thrive in a fire-adapted landscape?

Upcoming Events

Compost Giveaway with the Daily Acts @ Sonoma Garden Park | Sonoma | California | United States

Looking for a way to honor and give back to the environment!? Come out to Daily Acts and Sonoma Ecology Center’s Compost Giveaway September 27 and 28 from 4:00-6:00 pm.

Come pick up FREE compost for your yard and gardens to improve the health of both your soil and plants while drawing down climate-warming, atmospheric carbon. We can provide some old grain bags, but we encourage that you bring your own buckets, bags, or truck. We will be providing compost on a first come, first served basis with a max of 1 yard (which looks like the equivalent to an average truck bed full of compost). Please also bring shovels and gloves to help load up the compost.

Please register for a time slot so we are prepared of how many people to expect and to mitigate traffic. By registering you will also receive resources on the topic of Compost and Carbon Sequestration via email.



Volunteers play a crucial role at keeping Sugarloaf Ridge State Park open and accessible to all! Help Sugarloaf with trail restoration work by coming to our every-other-Thursday Volunteer Trail Crew. Activities include bridge and step construction, installing signs, clearing, lifting, carrying, and hiking.

Bring gloves, hat, and water that you can carry hands-free (i.e. bring a backpack). Wear long pants, boots or sturdy shoes and sunscreen. Long sleeves are suggested as poison oak is present. We have tools and trained crew leaders with tasks for all. Minors must be accompanied by a responsible adult. We will provide tools, and if allowed, lunch.

If you are a current Sugarloaf volunteer, log onto Better Impact to sign up. First-time volunteers are welcomed and encouraged to formally join our volunteer program if they’d like to support us more frequently. Start here to become a volunteer.

Full Moon Hike (Sold Out) @ Sugarloaf Ridge State Park | Kenwood | California | United States

Bring a flashlight and your sense of wonder as you explore the park after dark. This hike begins at the White Barn and heads up to the viewpoint on Vista Trail, where we will see the moon rise over the Mayacamas and the sun set over Sonoma Valley.

This is a moderate-to-strenuous, 4.2-mile hike with 700ft of elevation not recommended for children under 7.

Tickets are $10 general, and $5 for students, youth (12-17 year olds), Sugarloaf members, Sugarloaf volunteers, and free for children 7-12 years old. All minors must be accompanied by a responsible adult. Be at the meeting location at least 10 minutes prior to the start of the hike for a prompt departure. Bring water, snacks, and extra layers for the evening. Parking fees apply.

Ease of access: the White Barn parking area has one van-designed parking spot and one accessible porta-potty. The Lower Bald Mountain Trail has two trailheads; one starting from the main parking lot and one starting from the group camp. It is a single-track dirt and gravel trail with multiple narrow switchbacks and inclines for an elevation gain of approximately 500ft. Vista Trail is a narrow, single-track dirt trail with steep, rocky, slippery sections and multiple sections of stairs. Grey Pine connects Vista Trail to Meadow Trail. The section between Vista and Meadow is a double-track dirt trail with a creek crossing. Hikers cross a plank to continue onto the trail. Meadow Trail is a mostly flat composite trail manageable by strollers and wheelchairs from the trailhead to about a mile in, although officially not an ADA-compliant trail.
