Chapter Activities

Explore native plants, get involved, and connect with our Solano County community.

Field Trips

Hailing from a county rich in native plant habitat, our small chapter focuses on Spring hikes that showcase Solano County’s botanical treasures across select locations.

Join us for occasional guided outings and explore nearby activities with CNPS Napa Valley and East Bay Chapters.

Chapter Programs

The WLJ Chapter hosts occasional native plant talks. We encourage members to explore diverse programs by nearby CNPS Chapters and the Sonoma Center for Environmental Inquiry.

Interested in presenting? Email us at contact@jepson.cnps.org.

Volunteer Opportunities

WLJ Chapter volunteers operate a Vallejo nursery to cultivate native plants for sales and conservation every Monday and Thursday, 10-12. Contact Barbara to learn more!

Volunteers also collect acorns and grow oaks at the nursery for our ReOak Solano Program, and helps the Solano Resource Conservation District with native habitat projects.

Upcoming Events

About Our Chapter

Our chapter is named after Willis Linn Jepson, California’s most distinguished early botanist born near Vacaville. Co-founding the Sierra Club and authoring influential books like A Flora of California, his legacy endures through the Jepson Herbarium and the Jepson Manual: Higher Plants of California.

Our chapter is also home of Jepson Prairie, one of the few remaining vernal pool habitats and native bunchgrass prairies in California. Located 10 miles south of Dixon, this rare habitat still remains despite agriculture development that has converted much of the grasslands of the Central Valley.

Conservation

Conservation work is our highest priority. We have joined Solano Together to defeat the California Forever project and direct growth to our cities. Through ReOak Solano County and partnerships with others, we support restoration of native plant habitats. We participate on the CNPS Healthy Nurseries & Habitat Committee to help stop the spread of plant pathogens like Sudden Oak Death to our open spaces.
