  • SO BE FREE (Bryophyte Chapter) Weekend
    All day
    04-01-2019-04-01-2019

    The Twenty-Fourth Annual
    Spring Outing
    Botanical Excursion
    Foray, Retreat, and Escape to the Environment
    !!!!!!!!!!!!!!!!!! SO BE FREE 24 !!!!!!!!!!!!!!!!!

    Brought to you by the Bryophyte Chapter of the California Native Plant Society!

    Friday to Monday, 29 March to 1 April 2019
    Rancho El Chorro in San Luis Obispo
    Coordinators: Ken Kellman, Ben Carter
    Founded in 1996, SO BE FREE is a series of West Coast forays started by the Bryolab at UC Berkeley, but open to all botanists. The main focus is on bryophytes, but we also encourage experts on other groups to come along and smell the liverworts. We welcome specialists and generalists, professionals and amateurs, master bryologists and rank beginners. SO BE FREE is held each spring, somewhere in the Western US, associated with spring break at universities. Evening slide shows and informal talks are presented as well as keying sessions with microscopes. In addition to seeing interesting wild areas and learning new plants, important goals for SO BE FREE include keeping West Coast bryologists (and friends) in touch with each other and teaching beginners. To see pictures and information from past outings, visit the SO BE FREE website at: https://bryophyte.cnps.org/index.php/so-be-free

    ☛ One important function of this year’s SO BE FREE will be to serve as the annual meeting of the Bryophyte Chapter of the California Native Plant Society. See: https://bryophyte.cnps.org/ for
    details, and to join!

    The 2019 SO BE FREE will be held in San Luis Obispo County, one of the botanical gems within
    California. Midway along the coast between San Francisco and Los Angeles, San Luis Obispo offers strong moisture gradients, a tremendous diversity of geological substrates and abundant open spaces that have been only lightly explored bryologically. Vegetation types range from moisture-loving closed cone coniferous forests near the coast to arid desert scrub in interior regions, with a diversity of chaparral and woodlands in between. The region is known floristically as a zone of transition, with representation of northern species in mesic areas, southern species in the drier coastal regions and even Mojave desert species in the eastern part of the county. Foray destinations will include Los Padres National Forest, many of the open spaces surrounding the city of San Luis Obispo, a private ranch in the interior and some of the best wildflower destinations in the state, all of which promise to be very rich in ephemerals, Bryaceae and Pottiaceae.

    Beginners are very welcome to SO BE FREE, and this year we will again have a workshop session for beginners at the start of the event. Saturday, Sunday, and Monday morning we will have field trips to satisfy all participants from neophyte to nerd! Field trip details are to follow. Access is being sought for private, State, and Federal lands.

    Cambria Wildflower Show

    The premier wildflower show on the north coast is scheduled for April 13 & 14 at the Vet’s Hall in Cambria (1000 Main Street) from 12:00 to 4:00 on Saturday and 10:00 to 2:00 on Sunday.

    We usually have around 400 species of plants on display collected from the coastal region from the county line to the North and Montana de Oro to the South. In the display, plants are grouped by family and labelled with scientific name and common name.  There are also notations for rare, invasive, and introduced. I think this would be a great event for any plant lover to experience.

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
