CNPS Santa Clara Valley Chapter Field Trips
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.

Wed May 25 10am - 2pm Bonny Doon Ecological Reserve (Santa Cruz County) (NO REGISTRATION NEEDED)
Join Joe Cernac in exploring Bonny Doon Ecological Reserve. This area is a unique ecological islet in the highlands of Santa Cruz Mountains, made possible by an abundance of erosion-resistant sandstone. This sandstone results in landscapes ranging from slopes with little soil, where beargrass makes its appearance, to deep loose sandy soils, where shrubs found in drier regions abound. Finally, at the area’s margins, redwoods and ferns make their presence.
Several species of manzanita will hold our interest. Bring lunch, snacks, and recommended 2+ liters of water. This hike is open to all comers, with no registration needed.
Directions: Parking is limited, so please carpool with others you know. The Preserve is located northeast of Davenport off Hwy 1. Exit Hwy 1 at Bonny Doon Rd. and head northeast. After 3.9 mi. turn right onto Martin Rd. (Bonny Doon Rd. becomes Pine Flat Rd. just before the intersection). In a mile the Preserve entrance will be on your left. Park near the fire station.

Wed Apr 27 9am - 4pm McLaughlin Natural Reserve (Napa and Lake Counties)
Join Reserve staff for a tour of the Donald and Sylvia McLaughlin Natural Reserve, a unit in the UC Natural Reserve System located near Lower Lake in Napa and Lake Counties. The reserve protects about 7,000 acres of unusual habitats, including serpentine soils as well as riparian woodland, blue oak woodland and savannah, grassland, and chaparral.
Late April is prime wildflower season and there should be a variety of flowers to see and enjoy. The iNaturalist list for the reserve includes 468 plant taxa. We will explore different areas of the reserve on foot and by vehicle. The visit will be led by reserve staff and will last most of the day. The group will need to arrive punctually and leave all at the same time.
The McLaughlin Reserve is managed by UC Davis and is not generally open to the public. It is located about a 3-hour drive from our CNPS SCV Chapter office in Palo Alto.

Fri - Mon Apr 29 - May 1 Blue Oak Ranch Reserve (Mt. Hamilton)
Join us at Blue Oak Ranch Reserve where we will explore the SCU Lightning Complex burn area and look for rare plants. Blue Oak Ranch Reserve sprawls across the steep slopes of Mount Hamilton just east of urban San Jose.
Plant communities include blue oak woodland, valley oak woodland, black oak woodland, coast live oak woodland, riparian forest, chamise chaparral, Diablan sage scrub, nonnative annual grassland, wildflower field and native perennial grassland. Blue and valley oak woodlands have become quite rare in California, and few are as protected from overgrazing and the encroachment of suburban development as those at Blue Oak Ranch.
We will explore the burn area and look for rare plants such as Santa Clara red ribbons, serpentine leptosiphon, and the fire follower Brewer’s calandrinia. We will also make natural history observations in iNaturalist for the 2022 City Nature Challenge, so we’ll be on the hunt for insects, reptiles, and other cool creatures as well.
This trip is for CNPS members only (please ensure your membership is up to date or join). Space is limited. No drop-ins please. RSVP is required to join us for the trip. To register, please visit Eventbrite to get your ticket.. Detailed trip information will be emailed to registered participants closer to the trip date.

Hike #2 was to see the progression of drought effecting Stile Ranch. There were 11 attendees including the co-leaders Stella Yang and Dee Wong, and Ken Himes as sweep. As the weather heated up without much winter rains, the grasslands along the trail had already started drying out and turning gold and silvery in color. The native grasses such as Elymus glauca, Melica californica and Melica torreyana had begun to set seeds. With most spring wildflowers finished flowering, the summer flowering plants that were in bud (during hike #1) were now flowering, such as the Monardella douglasii, Streptanthus glandulosus var. glandulosus.
