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).

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.

    Sunday, Oct. 22nd2:00-4:00 pm, iNaturalist Workshop, San Luis Obispo Botanical Garden

    Have you ever thought about keeping track of your own nature observations in an organized way so you could refer back to them? What if you could easily do that, as well as share your observations and photographs taken in nature, with a group of like-minded people online? Would you like to make meaningful contributions to scientific research? “Citizen science” is ordinary people contributing to scientific research and iNaturalist is the place to get started with any or all of the above.

    Join us to discuss how to use the iNaturalist website and mobile applications, what the options are, and how to customize your iNaturalist account for your personal interests. This workshop, led by Damon Tighe and Bill Waycott, will be a combination of hands-on classroom and field work.

    In preparation for the workshop, please sign up for an iNaturalist account online and create your profile. If you plan to use your mobile device(s), download and install the mobile app(s) on Android and IOS, prior to the workshop.  After the classroom component, we will visit the garden to use iNaturalist in real-time.  The SLO Botanical Garden is located in Chorro Regional Park, off of Hwy 1, across from Cuesta College and adjacent to the Dairy Creek Golf Course.
