CNPS Santa Clara Valley Chapter Field Trips
Chapter field trips are free and open to the public. Field trips are oriented to conservation, protection and enjoyment of California native plants and wildlife. A list of past field trips and reports can be found here.
Many other upcoming chapter activities are listed in the Blazing Star. You can also find many of our chapter field trips and other activities on our Meetup Group. Signing up on Meetup allows the trip leaders to send notifications in case of changes or cancellations.
In our region it is important to be prepared for hiking on rugged and steep terrain, wide temperature ranges and rapidly changing conditions at any time of year. Our hikes are often slow with many stops and standing around for long periods. All participants should wear sturdy footwear and carry sufficient water, sun protection, food, clothing layers, personal first aid and other supplies you may need. Also bring hand lens and binoculars for viewing plants and fauna.
Cell service is mainly restricted to cities and major highways. On your way to an outing do not rely solely on your phone. If you have any questions about your ability to participate in a particular field trip, please contact the trip leader in advance.
RSVPs on Meetup
Meetup announces the events when they are posted. This lets folks note the trip and date. The RSVPs open up one week before the event. If you are signed up for Meetup announcements, you will receive a second notice when the RSVPs open up. We do this to reduce the number of no shows as folks make RSVPs closer to the trip dates.

PAST FIELD TRIPS
NOVEMBER 2024
Sun Nov 10 from 10am – 12 noon - Fountain Thistle Work Party (San Mateo)
Join Don Thomas of the Santa Clara Valley Chapter and members of the Yerba Buena Chapter for our fall fountain thistle habitat restoration work party near the intersection of I-280 and Hwy 92.
Fountain thistle (Cirsium fontinale var. fontinale) is a federally endangered plant species that grows in an unusual specialized habitat, serpentine seeps, and is only found here and in few other nearby locations on the Peninsula. Its recovery here is a restoration success story. Once almost completely displaced by jubatagrass (Andean pampas grass), it has largely recovered here, as a result of the work done by CNPS volunteers in a cooperative project of the Santa Clara Valley and Yerba Buena Chapters. However, fountain thistle is still under threat from invasion by new jubatagrass seedlings, by other non-native plants, such as bristly ox-tongue, and by woody plants, such as coyote brush, threatening to convert the area to shrub land or woodland. We will see some end-of-season wildflowers, such as Western goldenrod (Euthamia occidentalis).
Bring sunscreen, water, a hat, layered clothing and wear long sleeves/pants. If you have them, bring tools, such as trowels, spades and shovels. Some tools will also be provided.
To register, please visit our Meetup page at https://www.meetup.com/California-Native-Plant-Society-Santa-Clara-Valley-Chapter/
We’ll meet at the end of Lessingia Court in San Mateo. For more information, contact Don at: This email address is being protected from spambots. You need JavaScript enabled to view it.

FEBRUARY 2024
Sat Feb 10 10:00am – 2:00pm Dirca Walk at San Francisco Peninsula Watershed (San Mateo County)
Join Chapter Rare Plant Chair Don Thomas to see the rare Western leatherwood (Dirca occidentalis) in the Crystal Springs Watershed along the Sawyer Camp Trail. This will be an easy slow-paced walk of about four miles round-trip, starting at the trailhead on Hillcrest and Highway 280, with a stop for lunch.
Dirca is one of the first plants to bloom each year, revealing its bright yellow hanging flowers from its bare winter branches. We will also have a chance to see other early blooming plants, such as hound’s tongue (Adelinia grandis) and trillium (Trillium chloropetalum).
Dirca is a rare paleoendemic plant native only to the San Francisco Bay Area, ranked by CNPS as 1B.2. (Read more about CNPS rare plant ranks at www.cnps.org/rare-plants/california-rare-plant-ranks.)
An optional additional short walk along the Sawyer Camp Trail will be to the Jepson Laurel. This was at one time the largest bay tree in California, but it has been declining for many years. Many large branches have died and broken off the tree over time, so it has been dethroned as the largest in the state.
Wear warm clothes and bring water and lunch.
RSVP is required to join us for the hike. Space is limited. No drop-ins please. To complete the required RSVP, please visit our Chapter’s Meetup page at https://www.meetup.com/California-Native-Plant-Society-Santa-Clara-Valley-Chapter/.

MAY 2023
Sun - May 7 10am-3pm Sierra Azul Open Space (San Jose)
Woods Trail Through a Gardener’s Eye: Locally Native Plants for Bay Area Gardens
With an Option for a Shorter Hike Ending at 12:30pm
California’s plant diversity is among the greatest in the world and many of our native plants are suitable for landscaping. It is easy to see why: locally native plants have evolved in local soils and microclimates and fit perfectly in Bay Area gardens.
Join Arvind Kumar, Ashok Jethanandani, Stephanie Morris and Vicki Silvas-Young on this walk along Woods Trail to learn about the native plants local to our area. Arvind and Ashok are home gardeners in San Jose with a special interest in local natives. Stephanie is a landscape architect and past Gardening with Natives Committee chair. Vicki leads many field trips for the Chapter, Santa Clara Valley Audubon Society and Open Space Authority.
This hike is particularly focused on native plants on the trail that work well in gardens (and are generally available at native plant nurseries). It is not a detailed plant taxonomy trip. Observing the microclimates, companions and mature sizes of locally native plants can be a fantastic way to learn more about native plant gardening.
This contour trail of the Sierra Azul range has gradual ascents/descents, and the north-facing aspect keeps it cool even on warm days. The plants are flourishing after this season’s extended rainfall, and many may still be blooming. Plan future additions to your garden armed with the knowledge of the many attractive shrubs, subshrubs, perennials, and annuals that grow naturally here.
The full-length walk is 5.6 miles (out and back), with 330 ft of elevation gain/loss. Dress in layers, appropriately for the weather. Bring a sack lunch and plenty of fluids.
For those wishing to take a shorter hike, we will also leave with the main group at 10am but we will turn back earlier and skip the lunch break, returning to the parking lot by about 12:30pm. The shorter trip is about 2.5 miles and is also perfect for families! Bring water and bring snacks if desired.
Directions: Take Hwy 85 to San Jose. Take the Camden Ave. exit and go south. In 1.8 mi, turn right on Hicks Rd. After 6.3 miles, turn right on Mt Umunhum Rd. The parking lot is immediately on the right. In Google maps drive to pin “Sierra Azul Parking Lot at Jacques Ridge.”
We will meet in the lot at 10am and plan to return by 3 pm. (If the lot is full, find parking on the opposite side of Hicks Rd. in Almaden Quicksilver Park’s Wood Road lot and walk back.)
RSVP is required to join us for the walk. Space is limited. No drop-ins please. To register, please visit the Meetup page at https://www.meetup.com/California-Native-Plant-Society-Santa-Clara-Valley-Chapter/
