    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.

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
