The one mile walk along the Arroyo de los Frijoles (Creek of the Beans) Trail between Pebble Beach and Bean Hollow Beach offers a close-up look at tide pools, wildflowers and colonies of harbor seals and shorebirds.

Cascade field is the best example of native coastal terrace prairie and associated wildflowers along the San Mateo Coast. Eight people joined California Native Plant Society member Toni Corelli (This email address is being protected from spambots.

In the past the prairie was managed through fire by the Native Americans to bring grazing animals into the area and enhance desired plants that produce seeds that were gathered for food. Coastal prairies require some sort of disturbance regime to sustain them--either by grazing or fire--or bushes will grow and the prairie will turn into coastal scrubland.

On September 15, 2013 I joined several other Chapter members in a field trip to visit Sharsmith Herbarium at San Jose State University. The trip was led by Curator Toni Corelli and Assistant Curators Teri Barry and Lars Rosengreen.
The herbarium is named for botanist Carl Sharsmith, who started the herbarium and collected and mounted over 15,000 specimens. We started our tour in the room with the many rows of cabinets holding the herbarium sheets.
The curators had taken out several specimen sheets for us to examine 
. We learned that the most damage to the specimens is from insects. Thus the first step for a dried, pressed plant specimen to become part of the herbarium collection is to freeze it for a week at -20 degrees F. When we examine the specimen we are to keep the sheet specimen-side up, and not roll or bend it in any way. After we examine the specimen we put the sheet in a special case designated for a refreeze before being restored to its permanent cabinet.
I like ferns so I enjoyed a good look at a specimen of Dryopteris arguta. 
This specimen had the roots tied to the page with special linen thread, and in other places the specimen was attached to the page with special linen strips. As you can see in the photo, each herbarium sheet has a unique identifying number, called the "accession number." The sheets contain labels identifying the specimen: The lower right is the original label, showing plant name, date collected and by whom, location found, and other information. A second newer, smaller label is being added to all the specimens now, giving the plant's name in the 1993 version of the Jepson Manual.
Our Photography Group is a great place to meet other native plant enthusiasts while improving your photographic skills and learning more about our native plants. It is open to all. The group has periodic meetings, photography outings and an active email list. The group has an on-going #MyPhotoOfTheWeek activity on the email list for group members to share their favorite shots with the group on a weekly basis. There is a monthly virtual meeting on zoom on the fourth Friday of each month for members to share photos and more -- everything from photography tips to organizational ideas to plant hot spots.
Our upcoming events can be found on Meetup and Facebook. Past events can be seen here.
To participate in our virtual activites, we recommend that you join our online discussion group.
