Beautiful. Sustainable. Sonoma.

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. More than ever, Sonoma Ecology Center needs your support 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?

We are preparing to conduct another carefully controlled prescribed burn at Van Hoosear Wildflower Preserve on May 21, 2021 from 7:00 am – 6:00 pm.

Unplanned wildfires can be devastating, but planned burns can effectively remove excess flammable vegetation, manage invasive plants, and revitalize native plant communities such as the Preserve’s wildflower meadows.

Since 2004, we have worked with the owners of the Van Hoosear Wildflower Preserve to co-manage the wildflower meadows and grasslands, oak woodlands, and riparian habitats of the Preserve. This 162-acre property is protected forever against future development, to preserve its beauty and its rich and rare mix of native plants and animals.

Several non-native, invasive plant species grow in the Preserve. Some of them are not edible by cattle, so despite careful summer grazing, their populations continue to expand. Medusahead, for example, is an invasive grass that creates a thick layer of persistent, flammable thatch that smothers native grasses and wildflowers and has a prickly seed head that cattle avoid. A prescribed burn in 2020 at the Preserve made a good start at reducing Medusahead and other invasives. You may have also heard about controlled burns in 2018 at the Bouverie Preserve near Glen Ellen, and in 2016 and 2017 at Pepperwood Preserve, northeast of Santa Rosa, that successfully reduced Medusahead and reduced the burn intensity during the Nuns fire.

We are working with prescribed fire professionals, fire agencies, and air quality agencies to prepare for a safe and effective prescribed burn. Several factors could postpone or cancel the event.

It’s our intent to keep landowners near the Preserve informed. We’ll keep adding to this page as the event gets closer. If you have questions or thoughts you’d like to share, please contact Erica Warren at restoration@sonomaecologycenter.orgor (707) 200-8358.

Forest Therapy @ Sugarloaf Ridge State Park
May 22 @ 9:30 am – 12:30 pm

The practice of Forest Therapy has been shown to improve health and well-being.

Have you heard about Shinrin-yoku or Forest bathing? Here is an opportunity to take a walk and experience the practice for yourself. Learn techniques to maximize the health benefits and stress reducing qualities of this walking practice. Shinrin-yoku originated in Japan and is gaining popularity in the United States for its documented health benefits.

This practice takes a walk in the woods to another level. A centering and calming restorative practice, it promotes balance and restored vitality through a quality of presence and heightened sensory awareness. Recent articles have been written up in Oprah, Time Magazine, and National Geographic, as well as numerous other publications. Sugarloaf Ridge State Park hosts a Forest Therapy Series as part of its ParkRx Program the 4th Saturday of each month. These walks are led by certified ANFT (Association of Nature and Forest Therapy) practitioners. Visit for more info about this practice.

Tickets are $20 or free with a 2021 ParkRx from a Sonoma County Medical Provider (click here for more info).

We will hold two walks on May 22nd: 9:30am-12:30pm and 2-5pm. Tickets are only valid for the time selected.

Family Hike @ Sugarloaf Ridge State Park

This is a free event  but does require reservations as we are limiting the event to 12. Meet outside the Visitor Center. We will observe social distancing and mask-wearing. Parking fees apply and heavy rains cancel.
