Field Trip: San Mateo Wilderness
Sunday, May 1, 8:00 AM
Strenuous hike led by Ron Vanderhoff. The San Mateo Canyon Wilderness is one of the greatest natural resources in our area. This trip will take you, by foot, into the heart of the wilderness, remote San Mateo Canyon. We will hike the Fisherman's Camp Trail (1.7 miles) to San Mateo Creek and then follow the trail through the canyon westward to at least the intersection of The Bluewater Trail (another 1.7 miles). The rocks, plants and wildlife here are spectacular and still very wild. Full day. Meet 8 AM at the parking lot at Bravo Burgers, 31722 Rancho Viejo Rd., San Juan Capistrano (just off Hwy 74 near Int.5).
Field Trip: Union Wash
Saturday, May 7, 8:00 AM
This will be part driving tour and part hiking tour of this rarely botanized southern Owens Valley alluvial fan. The bottom of the fan is down in the Owens Valley's Great Basin flora, and as we ascend up the alluvial fan, we will enter into Mojave flora. There are also a few spring ecosystems with perennial water. With the long awaited El Nino moisture finally here, we can expect annuals alongside the persistent drought adapted perennial shrub flora. This will be a full day of exploring, so you will need to bring lunch, snacks, fluids and dress to be outside all day. Also have hand lens, field guides, and binoculars. We will meet at Independence Park, on the south end of Independence, on US 395 (Edwards St) at 8:00 am, and we should be done by late afternoon. Contact info: Jerry Zatorski .

San Gabriel Mountains Chapter
Program: The effects of historic drought in CA on chaparral
Thursday, May 26, 7:30 PM
Presented by Dr. Stephen Davis. Dr. Davis writes of this talk: “Over the last three years, California has experienced the worst drought in recorded history. We hypothesized that drought-hardy chaparral shrubs would display differential levels of drought–induced mortality, depending on their species. Our results supported this hypothesis, indicating the possibility of drought-induced changes in plant community structure." Dr. Stephen Davis is Distinguished Professor of Biology at Pepperdine University. He has been a visiting scholar at Stanford University, UCLA, University of Utah, and Baylor University. Eaton Canyon Nature Center 1750 N. Altadena Dr, Pasadena, CA 91107.
Yerba Buena Chapter
Nature Walk: Montara Mountain Manzanitas in Spring
Sunday, May 29, 11:00 AM - 3:30 PM
This trip is the second in the manzanitas-through-the-seasons series planned for 2016, allowing participants to observe plants in a single location as they go through their annual cycle of growth and reproduction. Mike Vasey is a coauthor of the excellent new Field Guide to Manzanitas. He will give tips on how to identify manzanitas and discuss what makes this a quintessential California genus. Montara's manzanitas already flowered in December-January, and by late spring we expect to see fruit and immature inflorescences. Meet at San Pedro Valley County Park near the visitor center, at the end of Linda Mar Boulevard in Pacifica. Seriously wet weather will postpone this trip to June 5. Contact: Gail Wechsler.
