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.

2014 Conservation Analyst Appeal Now Underway

We are entering our Chapter's ninth year of supporting a half-time professional Conservation Analyst! The funds needed, $40,000, are provided by Chapter members and supporters. We are asking for your generous contributions to this fund.

For two years, our Conservation Analyst, Mack Casterman, has provided indispensable support to the all-volunteer Conservation Committee. Mack is involved at all levels in our efforts to conserve our most valuable local native plants and the ecosystems they support. These efforts require specific knowledge about the locale and the plants, along with site visits, contacts with professionals and local citizens, document reviews and comments. Sustained effort is necessary. Some conservation issues on the agenda last for years, others demand immediate actions. We need to have Mack on the team to be as successful as possible.

Please contribute as generously as you can so we can keep Mack working with us. Mail a check made out to CNPS to California Native Plant Society, Box 5597, Elmwood Station, Berkeley CA 94705, or click on the PayPal button below.

Thank you!

Your help is needed to track Sudden Oak Death, the pathogen that is decimating our beautiful Coast Live Oaks. Well timed action can slow spread and save specific trees, as well as the many birds and other wild creatures that depend on oaks.

On Saturday, May 10, attend a 1-hr training at 10 am the Orinda Public Library (sign up at  wllhh@ymail.com) or at 1 pm on the UC Berkeley campus (sign up at http://www.eventzilla.net/web/event?eventid=2139027398.

On your own schedule Saturday or Sunday, look for infected California bay tree leaves. Return samples by Monday morning,. You can survey in your own back yard, by taking a leisurely walk or drive, or enjoying a vigorous hike. If you don't have a site or route in mind, we will recommend some.

For times of trainings in other parts of the Bay Area, go to http://nature.berkeley.edu/garbelotto/english/sodblitzparticipate.php. For general information on sudden oak death, go to www.suddenoakdeath.org.

The annual East Bay survey is organized by UC Berkeley's Dr. Matteo Garbelotto and sponsored by groups including Garber Park Stewards (garberparkstewards@gmail.com), Friends of Five Creeks (f5creeks@aol.com), and Friends of Sausal Creek (coordinator@sausalcreek.org).  Contact any of them for more information.

                          Saving Knowland Park


Blue scullcap (Scutellaria tuberosa) Photo taken in Knowland Park by Laura Baker

Over the past month CNPS and Friends of Knowland Park have continued to leaflet and picket the Oakland Zoo to inform visitors of the zoo’s plans to expand into Knowland Park. As we reach out to the public, we have been surprised to learn that many people thought that the project was killed when Measure A1 failed last year. Sad to say, despite growing public opposition to the California Trails project, the zoo continues down its stubborn path to destruction.

Through Freedom of Information Act and Public Record Act requests, we have learned that both the US Fish and Wildlife Service and the California Department of Fish and Wildlife have rejected the zoo’s claims that the impacts of the project are only temporary. continue reading

Guidebook to the Botanical Priority Protection Areas of the East Bay is now available online.  Click here to access this marvelous resource, which includes a beautiful interactive map.

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.

Please follow this link to join the East Bay Chapter of the California Native Plant Society, the Friends of Knowland Park and the Center for Biological Diversity in calling on the U.S. Fish and Wildlife Service to protect this park from the zoo’s destructive expansion 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.

For twenty years amateurs and professionals concerned with the East Bay flora have found Barbara Ertter’s Annotated Checklist of the East Bay Flora an indispensable resource. Now Dr. Ertter and restoration ecologist, botanist and photographer Lech Naumovich have produced a second edition incorporating a wealth of new information. The book is available at Native Here Nursery and at the East Bay Chapter membership programs.  It may be ordered from Delia Taylor, deliataylor@me.com.  You may also order the book online by clicking on the Paypal button labeled "Buy Now" and following the instructions. 



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:
