Chapter Activities

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 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.

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.

Local Plant List

Solano County harbors over 660 California native plant species thriving across eight distinct communities: alkali sink, chaparral, coastal prairie, coastal sage scrub, coastal salt marsh, foothill woodland, freshwater marsh, and valley grassland. Explore our plant list here.

Each chapter newsletter also features a native plant that thrives in Solano County.

Upcoming Events

About Our Chapter

Our chaper 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 work is our highest priority. We have joined Solano Together to defeat the California Forever project and direct growth to our cities.
