A Monterey Pine Tree Threw a Seed at Me

Technically, the Monterey pine tree threw the seed at my spouse who was standing on the deck outside of our house enjoying some sun. After the loud crack of a pinecone bursting open, one papery-winged seed wafted down onto the deck. Even though we live in the Monterey...

    The seed exchange is back!

    The workshop time slot (6.00-7.15) before the October meeting is reserved for our second seed exchange. So think seed collection. There will be a few minor differences. There has been a request to provide a picture of the plant that the seeds will become. This will help those who might not be familiar with the names choose plants they want to try. Our chapter will supply seed envelopes so we will be asking those bringing seeds to just bring a bulk collection of cleaned seeds labelled with genus and species, where and when it was collected and a picture. There is no need to spend your time separating into little envelopes.

    The seed exchange is an opportunity to share seeds from native plants which are growing in your landscape. We will not sell seed. Do remember the legal issues of seed collection. It is illegal to collect seed from private property and public spaces without permission. If you happen to have access to rare plant seed DO NOT collect it. That seed should be reserved for seed banks and those with the skills to nurture the plant to maturity.

    Keep in mind that a collection of plants grown from seed has more genetic diversity than plants grown from cuttings. Depending upon what your goal is that may be a positive point. But garden grown plant seed is not ideal for restoration planting. One would want the more pure genetics of a wild population to use for restoration. Plants grown from seed might not be like the parent plant.

    There is an article on our website under Resources that has information on seed collection and cleaning (link). You might find it helpful. Find it under Resources > Growing Natives.

It is 4 miles up and back, ascending 800 ft.  Come to learn the easy to identify plant and animal species.  To reach the trailhead, use a smart phone for guidance, because there are several windy streets involved.  Make sure to bring water and snacks. Sturdy shoes, sunscreen, hats, and layered clothing are recommended. No RSVP needed and dogs on a leash. Contact Bill Waycott, 805-459 2103. Rain or threat of rain cancels.

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
