Over the years, Dr. David Keil, professor emeritus Cal Poly-SLO, has documented the plants of California with an emphasis on plants of San Luis Obispo County and nearby regions. These lists represent a mountain of work, where he has carefully noted every species occurring in a particular area and later revisited the area to add and/or modify his findings.

Successful Seed Exchange

I want to extend a thank you to all who participated in the seed exchange in October. We ended up with over eighty species of plants. It was fun to see the interest of those who enjoy the propagation experience. Extra seed was packaged to sell at the plant sale in November and we managed to raise over $250 for our chapter.

Your spring wildflower garden

It’s time to start thinking about planting your wildflower garden with the winter rains coming soon. As in years past, we are beginning our rainy season late with a dry fall so far. This doesn’t mean we will have a dry winter, but this dry pattern is important when it comes to sowing our wildflower garden.

  • Chapter Meeting “Can you be a Sprouting Pine Nut”
    6:00 pm-9:00 pm
    11-07-2019

    Please join us on Thursday November 7 for a talk titled “Can you be a Sprouting Pine Nut?” about a plant community with some notoriety in our neck of the woods: Monterey Pine Forest. The story isn’t about the trees, which seem to grow everywhere in the California landscape and are found around the world in vast plantations – the story is about the natural Monterey Pine Forests of the Central Coast and the biological, economic and inspirational values these plant communities sustain. Nikki is a Central Coast native who will share the ecological story about Monterey Pine Forests and how a small group of pine enthusiasts in Carmel came together nearly 30 years ago to advocate for the conservation of native forest habitat.

    Nikki Nedeff is a Monterey County native with an enduring love of wild places and open spaces. Her professional experience spans more than three decades with non-profit conservation organizations and public resource management agencies in land acquisition and stewardship positions. Nikki’s academic background includes degrees in Biogeography from UC Berkeley, where her graduate work focused on riparian plant ecology. She teaches plant community ecology each spring at California State University Monterey Bay and works with the Big Sur Land Trust as Associate Director of Conservation. Email: nikki@ventanaview.net

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
