Our chapter functions thanks to many amazing volunteers.  The ones that might need to be contacted from outside the chapter are listed here.

Our chapter is governed by a Steering Committee composed of the four elected officers and any other jobholders who want to be on it and are approved by the committee itself.   Most of our jobholders are listed in this table. Seventeen of these are members of the Steering Committee.  Election of officers is held in October of even-numbered years.

Your membership provides financial support to the organization doing the most to preserve California's rich native flora.

Your membership makes you part of a group of like-minded people interested in, enthused by, and appreciating native plants.

Your membership gives you a way to share and spread your appreciation of native plants.

Your membership brings you our quarterly chapter newsletter Darlingtonia (on paper or online), the thrice-yearly state journal Fremontia, the quarterly Flora, and discounts at local and state plant-related retailers (See the most recent newsletter and the state web site for details.).
