Orange County Chapter
Field Trip: San Onofre State Beach
Sunday, May 3
With permission from CA State Parks and MSMC Camp Pendleton, our group will explore a coastal blufftop with small vernal pools, supporting one of California's rarest species, Pendleton button-celery - Eryngium pendletonense. We will have restoration ecologists on hand to discuss the pools and their restoration as well as CA State Parks biologist Lana Nguyen. We will likely visit another nearby restoration site which is employing innovative approaches to remove invasive mustards and other adventitious plants and return the area to a naturally functioning ecosystem. We will then likely visit the site of the March 2014 wildfire and view various wildflowers and a nice display of other fire-following plants. Depending upon group interests, a few may want to extend the afternoon into an optional hike down to the coastal beach and adjoining canyons to see the uncommon Emory's rockdaisy - Perityle emoryi and others. Meeting time and location is pending. Check www.occnps.org after 7 PM the night before for details. Note: this trip does require an entrance fee to San Mateo State Park! Irregular water and restrooms. Bring lunch and water for the optional extended trip.

Los Angeles/Santa Monica Mountains Chapter
Program: Sepulveda Basin Wildlife Areas - Past, Present, and Future
Tuesday, May 12, 7:30 - 9:00 PM
The Sepulveda Basin is the home of a Wildlife Area with an 11-acre lake, the Bull Creek Ecological Restoration Area, one of only 3 soft-bottomed portions of the Los Angeles River, Encino Creek, Woodley Creek, and Hayvenhurst Creek, plus Lake Balboa. The Sepulveda Basin was in the national news in December 2013 when the Army Corp of Engineers destroyed vast swaths of mature native vegetation under the guise of removing non-native plants. If you want to find out what happened and what are the current plans for restoring that area, attend this presentation by Steve Hartman, currently the chair of the Sepulveda Basin Wildlife Areas Steering Committee. Sepulveda Garden Center, 16633 Magnolia Blvd. Encino, CA.
Sacramento Valley Chapter
Program: A Simplified Geologic Overview of California's Great Valley and Geomorphic Development of Vernal Pool Habitats
Wednesday, May 13, 7:00 PM
Many people in our region have learned to love California's vernal pools and the unique array of plants and animals found in these ecosystems. Superbly adapted to their environments and the extreme seasonal fluctuations we enjoy here in California, these flora and fauna are both beautiful to behold and wondrously fascinating to study. But have you ever wondered how these vernal pool habitats formed in the first place? Not only are vernal pools distinctive biologically, they are geologically unique as well! Local geologist and earth science educator Nate Manley will be providing a geologic overview of California's Great Valley, illustrating how a myriad geologic processes and more than 200 million years of Earth history have shaped our state and contributed to the evolution of the vernal pool ecosystems we enjoy today. Shepard Garden and Arts Center, McKinley Park, 3330 McKinley Blvd., Sacramento, CA.
Monterey Bay Chapter
Program: Introducing Bryophytes (The Other Land Plants)
Thursday, May 14, 7:00 PM
Bryophytes (mosses, liverworts, and hornworts) represent a completely different solution to the evolutionary problem of living on land. They lack the complex vascular system that has made the so-called "taller plants" so successful, but they have evolved complex solutions that will surprise you. Ken Kellman will show us how to recognize this important group of plants with a short presentation, and then we spend the rest of the evening looking closely at many common bryophytes from the Central Coast. Speaker Ken Kellman met his first bryophyte in 1995 during a vascular plant survey of Quail Hollow Ranch in Santa Cruz County. It did not take long for him to abandon normal botanizing in pursuit of these tiny plants. He has published A Catalog of the Mosses of Santa Cruz County and is now collecting for a similar project in Monterey and San Mateo counties. His explorations have revealed several species new to science, and many more new to the central coast and the state. Pacific Grove Museum of Natural History, 165 Forest Ave., Pacific Grove, CA.
Kern County Chapter
Program Meeting, Plant ID, and Native Plant Gardening
Thursday, May 15, 6:00 PM - 9:00 PM

At 7:00 the meeting will begin with two speakers: Michael Clem will offer a report on the CNPS Conservation Conference and Clyde Golden will speak on the wildflowers of the Mill Creek Trail. Hall Ambulance Community Room 1031 21st St, Corner of N St & 21st St, Bakersfield, CA.

Bring your unknown native plants to ID before the talk. Venue: Santa Barbara Botanic Garden, Library, 1212 Mission Canyon Road, Santa Barbara, CA.
Santa Clara Valley Chapter
How I Did It: Creating a Bee-Friendly Native Garden
Friday, May 29, 7:00 - 8:30 PM
Most people are aware of the honey bee crisis, but honey bees aren't the only ones in trouble. Other pollinators are also in decline. Since this crisis, researchers have put more emphasis into studying all pollinators and learned that native bees not only pollinate crops alongside honey bees, but they also improve the efficiency of honey bee pollination. At this talk learn how to create a bee-friendly garden for honey and native bees - giving them a place in which to live, eat and raise their young, while attracting other wildlife such as butterflies, birds, hummingbirds and more. We'll also enjoy a humorous look at native "bee- haviors." Debbie Ballentine joyfully shares her knowledge of California native plants, wildlife gardening and sustainable landscaping through her writing, speaking, and photography. Saratoga Library, 13650 Saratoga Ave., Saratoga, CA.
Sierra Foothill Chapter
Field Trip: Hammill Canyon/Herring Creek Rd
Saturday, May 30, 9:00 AM
Hiking Level: moderate (some rough ground and a small amount of cross-country hiking). Leader: Jennie Haas. This area contains diverse habitats and a 2,400 ft elevation gain along the road from Hwy 108 to the top of the loop in Hammill Canyon. There is a great diversity of plants. We're hoping to see the peony in bloom at this early date. Meet at 9:00 in the parking lot between the KFC restaurant and Kohl's, on Mono Way in Sonora. For more information contact Jennie at (209) 962-4759.
