The LA County Board of Supervisors will consider whether or not to approve the proposed Centennial development next Tuesday, December 11. Although this project is located in LA County, we believe this is an issue that impacts all of California, both in terms of our...read more

For a native plant novice like me, joining the California Native Plant Society seemed like a good idea so I became a member of the San Luis Obispo chapter. My spouse and I attended our first meeting a year ago last October. That is where I met Marti and the real fun began.read more
Last month we discussed California ground squirrel problems, this month I will focus on the gopher aka Botta’s pocket gopher (Thomomys bottae). For most of us, gophers can sometimes be a headache but a livable one. They come and go between you and your neighbor’s yard, only losing a couple of plants a year. For yards like these I recommend using …read more
The cover of this Obispoensis is another beautiful water color by Heather Johnson. In our area Hummingbird sage can grow in an extensive mat. Its leaves are large (10 in (20 cm) long and 3 in (8 cm) wide). The leaf surface appears quilted. Its family affiliation (Mint or Lamiaceae or Labitae) is shown clearly in Heather’s water color.read more
California Dudleyas are easy to grow. Illegal wild collection can be disrupted via legal propagation. I propagate Dudleya with middle school science classes. If seventh-graders can grow these natives from seed, you can too. Home gardens are a good source of Dudleya...read more

Speaker: Dena Grossenbacher, Alpine plant diversity on Yosemite’s Sky Islands
Dena Grossenbacher is a new Assistant Professor of Botany at CalPoly. She is broadly interested in how plant-environment interactions generate and maintain plant diversity, and the processes underlying the origin and extinction of species. She uses the California flora,
especially monkeyflowers, to address these questions because of their astonishing variation both among and within species.
Dena received a Bachelor’s degree in Botany in 1999 from University of Washington, was a field botanist in the Pacific Northwest and the Yosemite region from 2000-2008, and received a Ph.D. in Population Biology from UC Davis in 2013 with Maureen Stanton. She did postdocs studying mating system evolution at University of Minnesota and at Washington State University before arriving at Cal Poly
in January 2017.
Chapter meetings are generally held the first Thursday of the month at the San Luis Obispo Vets Hall on Grande Ave near the corner of Monterey Street.
Our meetings kick off with a social time that begins at 7:00 p.m. This is a time to sample the treats that members have brought along to share, and browse the book table. The meeting starts at 7:30 p.m. with some brief announcements before the program begins.
Speakers and notes from Chapter Meetings are documented in each Obispoensis newsletter. Please see the Obispoensis archive for PDF file of each newsletter.

Saturday, Nov. 11th, 8:30 am to 11:30 am
Work Crew, Old Prospector Trail, Irish Hills
Meet in the Costco parking lot, adjacent to the Costco gas station, Los Osos Valley Road, SLO. From there, we will walk to the trail.
Join hikers who want to help keep trails in good shape. We will be using loppers to remove branches of Ceanothus and other chaparral plants out of the trail, then cache the cut pieces off the trail.
The upper half of the trail was completed in October, so work will focus on the lower half. Total distance will be 3 to 4 miles with a 500 ft. elevation gain. Use a small backpack to bring water, snacks, and sunscreen. Wear sturdy shoes, bring gloves, a hat, and layered clothing, as needed. Contact Bill Waycott, (805) 459-2103, email@example.com.
