  • A Photographic Journey of California Lupines with Stuart Wilson

    CHAPTER MEETING MAY 4TH IS OUR NEXT MEETING

    A Photographic Journey of California Lupines

    Stuart Wilson has long held a love and fascination of the genus Lupinus. After many springs spent photographing our local species, he decided to embark on a project to photograph every species and variety (104) found in California. Traveling throughout the state in 2015 and 2016, he has reached his goal (with a few noteworthy exceptions). He will give an overview of the great variety of forms found in the genus with tips on identification.

    Stuart Wilson has been interested in photography since high school. After college in Orlando, Florida, he moved to Santa Barbara to study at Brooks Institute. He has traveled extensively in pursuit of nature subjects such as insects, amphibians and reptiles, and other small animals. He markets his photography through Science Source, a stock agency based in New York. He produced most of the photographs for Joan Lentz’s book. A Naturalist’s Guide to the Santa Barbara Region. He is a past president of Channel City Camera Club in Santa Barbara. Visit Stuart’s website to get a taste of the beautiful photographs featured in his talk.

    LUPINE WORKSHOP ADDED PRIOR TO MEETING – COME AT 6PM TO ATTEND THE WORKSHOP

    The CNPS monthly meeting Thursday, May 4 at the San Luis Obispo Veterans Hall will kick off with a workshop from 6:10 to 7:00 pm on lupine identification led by Dr. Dave Keil.

    Our county is home to a diversity of Lupinus species, two of which grow nowhere else.  Dave will give a quick intro to lupine features, and participants will then have the opportunity to try out the draft treatment on Lupinus from the nearly completed second edition of The Vascular Plants of San Luis Obispo County, California.  Bring your hand lenses!


    June is bringing a crammed-full sales table to the May meeting. Think of all those birthday gifts you have to buy, all your ugly T-shirts that need replacing, the thank-you gift to your maiden aunt, and the financial support you wish to give CNPS.

    NEW ITEM JUST IN TIME FOR SUPERBLOOM. As well as the downloadable version, we have a CD with two versions of the program available at the sales table

  • Indian Knob on the Guidetti Ranch

    Guidetti Ranch

    Saturday, May 13, 9:00 am, Indian Knob on the Guidetti Ranch with ECOSLO

    Hike with a docent from the SLO Stewards Program to Indian Knob at Guidetti Ranch in the hills just south of the city of San Luis Obispo. This is a hike is one that can only be done with a docent since it is a private ranch under a conservation easement, and we only do it three or four times a year. Hopefully during the hike, we will see the two endemic flowers which the ranch has on it – the Indian Knob Mountain Balm and the Pismo Clarkia.

    We will meet at 9:00 A.M. to carpool to the ranch, since there is not very much parking at the entrance to the ranch. This is a moderately strenuous hike, is approximately eight miles with an approximate 600 feet gain in elevation. The last half mile or so to Indian Knob the trail is very overgrown, so be prepared for some bushwacking. Since all of the hikers are required to stay with the docent, you will not be able to turn back whenever you want, so you must be prepared to hike the full eight miles.

    Bring water, sunscreen, and a lunch with you; wear sturdy shoes; and be prepared to get back to our cars about 2:00. Also, since this is on private property, no dogs are allowed.

    Only 20 people are allowed on this hike, so you must email Carolyn Huddleston, who is a volunteer with ECOSLO (the Environmental Center of San Luis Obispo) to reserve a spot; her email is carolyn.j.huddleston@gmail.com. If you are unable to go with us this time, you can email Carolyn and get your name put on the notification list for the next hike at the Guidetti Ranch, and she will email you the next time one is planned.

Volunteer at the Hoover Herbarium

During the volunteer sessions at the Hoover Herbarium, people can take part in any number of activities.  One of our primary responsibilities is mounting new specimens.  This involves taking dried and pressed plants and glueing them to paper.  When we mount plants, we do it in such a way that those specimens will last for hundreds of years.  Each specimen is a physical record of what plants occurred where and when.  Without this valuable information we wouldn’t know when a species goes extinct, expands or contracts its range, or where species occur.  After mounting, the specimens are databased and geo-referenced.  Then they are filed into the main collection. We have over 80,000 specimens at the Hoover Herbarium.  We are also working on a SLO Voucher Collection, which will contain one representative specimen for each species in the county.  Volunteers look through our specimens and pick the one that should be added to the Voucher Collection.  Additionally, we are actively working on our moss and lichen collections.  Volunteers can choose what aspects of the work they would like to participate in.  Any and everyone is welcome. The Hoover Herbarium is located on the 3rd floor of the Fisher Science Building (33) in rooms 352 and 359.

Starting Sept 18th, the herbarium volunteers sessions will be Mondays from 3-5 pm and Fridays 9 – 1.
Parking permits are required on campus Monday through Thursday, 7:00 am through 10:00 pm; and Friday, 7:00 am through 5:00 pm. You can either buy a $6 day pass, a $4 3-hr pass, park in a metered space, ride the bus, or park off campus and walk in.  Questions: email Jenn Yost at jyost@calpoly.edu
