The landscape of our community has changed. Now is the time to harness our strength and spirit, together. We will be with you every step of the way, to rebuild a community that is more resilient, healthy and thriving.


How is our Valley doing? We monitor, analyse, map, and report on broad measures of ecological health in Sonoma Valley.


We provide educational and outdoor programs for thousands of students in Sonoma Valley.


We foster and maintain publicly accessible open spaces, including Sugarloaf Ridge State Park, Van Hoosear Wildflower Preserve and the Sonoma Overlook Trail.


Since 1993, we’ve worked side by side with landowners and volunteers on projects that restore, protect, and improve our natural heritage.


Sonoma Ecology Center is committed to working with the community to make Sonoma Valley more thriving and sustainable than ever before. Anyone looking for useful information on ways to help is invited to click on the links below.

8:30 am hasta 12:30 pm

Reuniremos a la Luz Center, 17560 Greger St., Sonoma

Únete a los naturalistas del Centro de Ecología Sonoma en la Preservación de Flores Silvestres Van Hoosear para la vista más increíble de flores silvestres en todo el condado de Sonoma. Tenga una experiencia de una pradera primaveral inmaculada con muchas especias en flor. La propiedad de 66 hectáreas en las faldas de la montaña Sonoma está protegida por el Distrito de Preservación Agrícola y Espacios Abiertos del Condado de Sonoma (Ag + Open Space) y el Consejo de Conservación de Vida Silvestre de California. La propiedad es manejado por el dueño y el Sonoma Ecology Center para proteger las plantas únicas, los arroyos, y el hábitat de la vida silvestre.
Esta excursión es un nivel principiante con una pendiente suave. La mayoría de la caminata es por una pradera generalmente sin senderos. La caminata cruza algunos arroyos que algunas veces tienen agua poco profunda con unos caminos de piedras.
No hay cobra para esta excursión a causa de los votantes del condado de Sonoma que financian el trabajo de Ag + Open Space en un impuesto de ventas de un cuarto centavo.
Lluvias torrenciales cancelarán el evento.
¡Registrate hoy! Registraciones son requeridos por teléfono o internet a más tardar 5 pm el día antes de la caminata. Iremos juntos de La Luz Center hasta Van Hoosear Preserve. Para más información o preguntas contacta a Alana Fichman (707) 591-1726 o alana@sonomaecologycenter.org.

Harvest Market Reopens for Season @ Sonoma Garden Park | Sonoma | California | United States

Sonoma Garden Park’s beloved Harvest Market is officially reopening for the season on Saturday, April 21, from 9 a.m. to 12 p.m. The Harvest Market will remain open every Saturday through late summer.

Featuring fresh-grown produce including lettuce, bok choy, radishes, kale, cilantro, salad mix, eggs and olive oil, the Sonoma Garden Park is a favorite grocery source for Sonoma residents. Everything is organically and sustainably grown right on the Garden Park’s 6.1 acres except for the olive oil (which is grown and pressed nearby).

Local gardeners have an additional resource: UC Master Gardeners will be on hand during Harvest Market hours to answer all gardening and horticulture questions regarding pest management, the seasonal planting calendar, and anything else you can think of.

A variety of veggie starts – propagated at the Garden Park’s on-site nursery – also are for sale throughout the season.

Come join us in the Straw Bale Barn, buy some produce, and take a stroll around the beautiful Garden Park as our spring flowers begin to bloom. Then come back on subsequent Saturdays and keep stocking up!
