    CHAPTER MEETING June 6th 2019 – Thursday – 7:00 pm
    7:00 social, 7:30 program
    Veteran’s Hall, Grand Avenue at Monterey, San Luis Obispo

    Reed Kenny, MS Candidate, Cal Poly, CNPS McLeod Scholar, Floristic Survey of Halter Ranch, San Luis Obispo County,
    California

    Halter Ranch, a portion of which is a working winery, is approximately 2,000 acres in size and has areas of intact oak woodland, grassland and manzanita chaparral. Located in northern SLO County near Adelaida, it includes portions of the historic MacGillivary Ranch, which hasn’t been surveyed by botanists since 1984, and additional areas that may not have been surveyed at all. This talk will summarize the results of this season’s field surveys.

    With Dr.’s Matt Ritter and Dave Keil, Cal Poly.

    Paul Excoffier, MS Candidate, Cal Poly, CNPS McLeod Scholar, Climate Change and San Joaquin Woollythreads (Monolopia congdonii)

    San Joaquin woollythreads, Federally-listed as Endangered, was historically found throughout the rain shadow of the southern Coast Ranges. However, the current range of M. congdonii has been greatly reduced by habitat loss. Current conservation strategies for M. congdonii focus on conserving extant populations and re-establishing populations within its historic range. However, climate change represents a key unknown in determining if these strategies will be successful. This talk will discuss work in progress on testing the performance of M. condonii and other winter annual species under simulated future climates and investigation of its seed longevity.

    With Dr. Nishanta Rajakaruna, Cal Poly, and Ryan O’Dell, Bureau of Land Management.

The Arroyo de la Cruz area features a variety of plant communities and a number of endemic, and rare plants found only in this relatively small area.

    Meet at the Elephant Seal Overlook (first entrance on the left going north) at 9:00 am. For those wanting to carpool from the south, meet in the Santa Rosa Park parking lot in San Luis Obispo at 8:00 am.

Volunteer at the Hoover Herbarium

Where is the Hoover Herbarium located?

The Hoover Herbarium is located on Cal Poly SLO campus on the 3rd floor of the Fisher Science Building (33) in rooms 352 and 359. Questions: email Jenn Yost at jyost@calpoly.edu

What do volunteers do?

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.  Anyone and everyone is welcome. Questions: email Jenn Yost at jyost@calpoly.edu

What days/hours do you need volunteers?

Hoover Herbarium volunteers sessions are Monday 3-5 pm and Friday 9 – 1. Questions: email Jenn Yost at jyost@calpoly.edu

Where do I park?

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
