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).

Why Grow Natives from Seeds?

by Marti Rutherford. You have probably wandered the nursery isles looking for the ever more popular native plants being sold. Do you ever consider how those plants have been propagated?

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.

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.

    New Reservoir Canyon Trail Plant Walk

    Join us for a plant ID walk in Reservoir Canyon and the new trail that leads to Bowden Ranch. The focus of this fieldtrip will be riparian and serpentine plant communities, plants one would regularly encounter throughout much of the greenbelt surrounding the city of San Luis Obispo. It is 4 miles up and back, ascending 800 ft. The ascent is gradual, along a winding trail towards the top of the ridge. Come and learn the easy to identify species. Pick out plants that attract you. Bring native plant samples with you to be identified.

    Meet at Santa Rosa Park in SLO at 8:45 am (to car pool to the trailhead) or at the Reservoir Canyon trailhead at 9:00 am (parking can be limited). Make sure to bring water and snacks. Sturdy shoes, sunscreen, hats, and layered clothing are recommended. No RSVP needed and no dogs please. Also, bring paper and pencil to take notes, and a camera for a photo record. If you would like a preprinted copy of the plant list for this walk, let the hike leader know 24 hours in advance.

    For more information, contact Bill Waycott, (805) 459 2103, bill.waycott@gmail.com.

    Program: Travels with a Geobotanist: Plant Life on Serpentine and other Harsh Soils with Dr. Nishi Rajakaruna

    Dr. Nishi Rajakaruna fell in love with plants at a young age during a visit to Sinharaja Rainforest, Sri Lanka. He received a BA in human ecology from the College of the Atlantic, and an MS and PhD in botany from the University of British Columbia. He conducted post-doctoral research in plant ecology at Stanford University. His research examines how plant diversity, ecology, and evolution are influenced by serpentine and other ‘unusual’ soils, including those with heavy metals. He has taught botany at College of the Atlantic and San Jose State University during the last 12 years and is currently an associate professor in plant biology at California Polytechnic State University.
