Members’ meetings

East Bay CNPS Members’ Meetings are great for:
* Learning about native plants (and wildlife) and their habitats
* Virtually visiting beautiful and interesting places
* Being inspired by conservation challenges and success stories
* Meeting nice people who share your interests

Our meetings are always free and open to everyone, members and nonmembers alike. We meet at 7:30 pm on the fourth Wednesday evening of the month in January-May and September-November, with a slight adjustment in the schedule to avoid Thanksgiving week. Most of our meetings take place at the Orinda Library or Orinda Community Center, which are centrally located in our big, two-county chapter area.

We welcome your ideas for topics or speakers (some of our best programs have come from members’ suggestions), so please feel free to contact Programs chair Sue Rosenthal with your ideas ( or 510-496-6016).


North American Cercis (redbud): a study of evolution and adaptation
Speaker: Camille Nowell, MSc
Wednesday, February 22, 7:30 pm
Location: Garden Room, Orinda Public Library (directions below)

Camille Nowell with redbud

For many centuries Cercis, a genus of attractive woody , a genus of attractive woody plants that includes our native western redbud, has been a focus of botanical study and appreciation. The first recorded mention of the group was by the ancient Greek philosopher Theophrastus, circa 325 BC. Native Americans, distinguished botanists, and eminent statesmen have also taken an interest in Cercis, including Carl Linnaeus, George Washington, Thomas Jefferson, Edward Lee Greene, Milton Hopkins, and Duane Isley.

More recently scientists have been investigating this group to better define its species and to understand its global patterns of distribution. The traditional taxonomic treatment of Cercis described two species in North America: the eastern species C. canadensis and the western species C. occidentalis (western redbud). In her master’s research on Cercis, Camille found through DNA analysis that Cercis in the Colorado River drainage may in fact be a different species. In her presentation, Camille will introduce the redbud genus and explain how she determined there could be a “cryptic” third species in North America.
Camille Nowell has conducted detailed botanical surveys in the Mojave Desert, the Sierra Nevada, and the San Joaquin Valley. She recently earned her M.S. degree in Ecology, Evolution, and Conservation Biology, with an emphasis on California native flora. Her research on Cercis took her on expeditions throughout montane California and the Colorado Plateau. She has also enjoyed working on barn owl, golden eagle, and prairie falcon studies for the East Bay Regional Park District.
