California Native Plant Society

The California Native Plant Society (CNPS) was formed in 1965 in the East Bay region. Today it is a statewide organization with thirty-three chapters. The East Bay Chapter covers Alameda and Contra Costa Counties. The state organization and the local chapters work together to increase understanding of California's native flora and to preserve this rich resource for future generations.

Donations in support of the activities of the East Bay Chapter of the California Native Plant Society in pursuit of its mission are much appreciated.

Conservation Analyst Appeal

Having a professional Conservation Analyst has made a huge difference in our actions to protect our local native plant habitats.  Now that Mack Casterman has gone on to a full time job, our volunteers missed his work immediately and have been scrambling to keep up in his absence. 

We will soon hire a new Conservation Analyst and must provide for his/her support, hence the beginning of the 2016 Conservation Analyst Appeal.

All contributions are very much appreciated.   To donate click on the Paypal button below or send a check made out to CNPS to our mailing address:

Save Knowland Park

Your help is needed to save Oakland’s largest city park – Knowland Park – from an unnecessary and destructive zoo expansion project! Despite pleas by a wide range of conservation groups to modify their project, Oakland Zoo executives have pushed forward with plans to bulldoze and build on rare wildlife and plant habitat, putting in danger threatened species like the Alameda Whipsnake, and the wide variety of wildlife that call Knowland Park home. Knowland Park is a critical piece of EBCNPS’s “Foothills of South Oakland” Botanical Priority Protection Area due to its acres of remnant native grasslands as well as a stand of rare maritime chaparral. Both habitats will be heavily impacted by the Zoo’s proposed development plan.To follow along with our work to save Knowland Park, please “like” us on Facebook and share this info with your firends and neighbors. You can also visit the Knowland Park Coalition website at saveknowland.org for up to date reporting on the ongoing efforts to gain permanent protection for this wonderful park. Knowland Park has been referred to as Oakland’s best kept secret, but we are hopeful that with your help it won’t stay a secret much longer.



The East Bay Chapter of CNPS wants to keep track of rare and endemic native plants and plant communities in the East Bay. Within our catalogue of native plant species there is an abundance of rarity: from Mount Diablo endemics to Pleistocene relicts; narrowly distributed taxa to peripheral populations; and species that have suffered extirpations from changes in vegetation composition resulting from the introduction of non-native plant species or directly from human development. Based on the CNPS Inventory of Rare, Threatened, and Endangered Plants of California, a total of 127 of these plant species are currently known from our Chapter area. These species are separated into five categories of rarity:
