Clarkia speciosa subsp. immaculata (Pismo Clarkia)

I chose the Pismo clarkia because it grows in the area surrounding Mardi’s home and nowhere else. It grows naturally in about 20 occurrences from the southern Edna Valley, south through the foothills and valleys of the Southern San Luis Range, ending east of Pismo Beach and Arroyo Grande (Huasna Valley).

Spring Wildflowers in Northern Santa Barbara County

2018 has been a surprisingly good year for spring wildflowers. Except for the January deluge and some good March storms, this has been a fairly dry year. In late September, 2017, several spot fires burned along Rucker Rd. just north of Mission Hills near Lompoc, California. In spite of sparse rainfall, there has been encouraging regrowth on trees and shrubs and blooming of wildflowers.

A Commentary by John Nowak, Plant Sale co-Chairperson

The other day, while checking out at the grocery store, the cashier noticed my CNPS hat and asked me, “How do you become an environmentalist?” I thought for a moment and then I told him “I would start at home.”

Plant Associations and the Geology of the Morros

Plant Associations and the Geology of the Morros

What you are seeing is a display of the underlying geology manifested in the soils that lie above the bedrock. The browning grasslands are floored with ‘melange’ of the Franciscan Formation, a unit composed of sheared shale and bits and pieces of the ancient seafloor that were squished into a subduction zone… kinda like what happens if you try and push a slice of pizza under a door.

Pigs Attack the Saltmarsh of Morro Bay… again

Pigs Attack the Saltmarsh of Morro Bay… again

Wild pigs are again active in Morro Bay, causing damage while rooting for the tuberous reeds in the brackish freshwater seep zones close to the high tide line. This time they are at Shark Inlet. We last saw them in 2015 on both sides of the South Bay Boulevard bridge, and neither of the locations appear to have recovered.

    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.

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, bill.waycott@gmail.com.
