On Sunday, we will visit the vernal pools in Sonoma Valley Regional Park near Glen Ellen before heading for home. Cost is about $20/person for camping and biologist fee. Sugarloaf Ridge is in the Sonoma Valley near Kenwood, between Santa Rosa and the City of Sonoma, so you may want to plan an extra day before or after the trip to do other things in the area.

Sun Mar 24 9am - 12pm First Day of Spring Beginner’s Bird and Plant Identification Walk @ Lake Cunningham Park (San Jose)

Do you love being outdoors? Do you want to deepen your appreciation of nature by learning the names of birds and plants around you? As Spring begins, join us for the first walk of its kind this year: a beginner’s bird and plant identification walk through Lake Cunningham Park. Lake Cunningham is a major destination for waterfowl and migratory birds, and its native garden is home for many resident birds for its habitat value. On this walk, Vicki Silvas-Young will show you how to identify the common birds of our area, as well as the native plants they depend on for food, shelter, and nesting places.

Difficulty Level: The distance is 4 miles round trip on a level path.

Notes: Bring a hat, water, your bird and plant list, and binoculars. Wear comfortable walking shoes. Parking fee is $6. Meet at the Marina building at 9:00 am. The Marina is on the western shore of the lake, next to Raging Waters, at the opposite end of the park from the main entrance on White Road. In google maps, search for "Lake Cunningham Marina" to be directed to the Marina.

Space is limited. RSVP via Meetup to reserve your spot. Cosponsored by CNPS, Santa Clara Valley Audubon Society, and Open Space Authority.

MAY


Sat May 11 - Wed May 15 Lost Coast Backpacking Field Trip (Humboldt County)

Join Joe Cernac and Trevlyn Williams for a 25-mile hike in 4 days along the Lost Coast, a pristine, undeveloped stretch of California coastline. Although there is virtually no elevation gain, this is a surprisingly strenuous off-trail hike on beaches, in sand and over rocks. We will take our time while Joe identifies plants and Trevlyn points out marine wildlife.

This website has detailed information on the Lost Coast but is somewhat outdated, reservations are now required and we need to purchase our permits at least 30 days in advance. With bear activity and no trees to hang food, bear canisters are required and we plan on renting them from the BLM office. For more information and to sign up for this field trip contact Joerg Lohse at This email address is being protected from spambots. You need JavaScript enabled to view it..

Itinerary: On Saturday May 11th, we drive to Shelter Cove, CA and meet at Black Sands Beach to carpool, rent our bear canisters and explore the area. From Sunday through Wednesday we will be hiking from Mattole Beach to Black Sands Beach along the Lost Coast. Projected campsites are near creeks and wind sheltered. On May 15, Black Sands Beach will be reached, car shuttle arrangements completed, and we will drive home.
