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?
Watch this video on how we keep people safer while supporting our environment.
TICKET SALES WILL END ON FEBRUARY 12, 11:59 PM. PLEASE REGISTER BY THIS DEADLINE.
Location: Multiple Locations around Sonoma County (including Sugarloaf Ridge State Park)
Sonoma County is full of amazing wildlife discoveries for those that know how to make them. From the Mountain Lions of Sugarloaf Ridge State Park, the shorebirds of Bodega Bay, tiny plankton, dragonflies, to big old bears, thousands of species of wild animals call Sonoma County home.
In this course, students will learn how to find, document, and observe a wide variety of our native animals through a series of field trips to natural areas. Emphasis will be on learning field methods that students can employ with only low-cost equipment, and on recognizing the major groups of animals and how to photograph them. We’ll learn some ecology, evolutionary biology, and conservation biology along the way, but our focus will be on the field methods. Scholarships are available to reduce costs for those in need of financial assistance, and carpools can be arranged for those needing transportation.
Instructor: Dr. Dan Levitis studied zoology at the University of California, Berkeley, and has taught zoology, ecology, evolutionary biology, demography, and conservation biology at the university level. For Sonoma Ecology Center he has previously taught New Ecological Scientist Training, California Naturalist Training, and Climate Stewardship, as well as leading programs to document the biodiversity of Sugarloaf Ridge State Park and the Sonoma Developmental Center. He is Community Science Coordinator for Sonoma Ecology Center.
We have reached our capacity for scholarships. Please contact Tony at email@example.com for questions.

Explore the different plant communities in Montini Open Space Preserve with us on Friday, March 31, 1:00-3:30 pm. For each community, you will learn about the blooming spring wildflowers found in the community, management concerns, and the factors that control the distribution of the community within the preserve.
The Montini Open Space Preserve was protected by Sonoma County Ag + Open Space in December 2005 for recreation and preservation of its natural and rich historic significance has been a working ranch since the time of General Vallejo. The preserve, which encompasses 152 acres, is in and adjacent to the City of Sonoma. With oak woodland, large rock outcroppings, and open grassland, the property offers beautiful views of San Francisco and San Pablo Bays.
Due to occasionally steep trails and uneven footing, the hike is rated intermediate; however, frequent pauses will allow hikers to catch their breath. There is no charge for the outing, which is made possible by the voters of Sonoma County who fund the work of Ag + Open Space with a quarter-cent sales tax.
Meet at Preserve entry – 4th Street West and Haraszthy Drive, Sonoma, 95476. Heavy rain will reschedule the event!

Join us for a guided hike at the beautiful 960-acre Saddle Mountain preserve above Rincon Valley, on the eastern boundary of Santa Rosa in the Mayacamas Mountain Range. The hike will be led by Sonoma County Ag + Open Space stewardship specialist Monica Delmartini, and SEC education program manager, Tony Passantino. This hike is organized by Sonoma Ecology Center on Ag + Open Space owned land that was recently touched by the Glass Fire. Delmartini is the resident fire ecologist and will discuss land management in a post-fire setting including, wildfire ecology, forest resiliency and the benefits of fire on California landscapes.
This is a moderately strenuous hike of approximately 4-5 miles with substantial elevation gain on established trails/fire roads. Please bring water and lunch, and be prepared for that day’s weather. There is a shallow water crossing. The hike will go on in light rain, but heavy rain will cancel the outing.
There is no charge for this outing, which is made possible by the voters of Sonoma County who fund the work of Ag + Open Space with a quarter-cent sales tax.
We will be meeting at Rincon Valley Public Library. For any other questions or concerns, please contact Tony Passantino by emailing firstname.lastname@example.org.
