2016 Rare Plant Treasure Hunts Announced Soon

Steve SchoenigThe CNPS Rare Plant Treasure Hunt (RPTH) season is off and running, trying to catch up to the early start to the flower season and ushering in a new statewide coordinator – Steve Schoenig. Many chapters and individuals have already been out; trying to either re-visit or discover new rare plant populations. With 1771 ranked plant taxa (not including list 4s) comprising a total 39,404 known localities keeping current data on population condition and threat status is a very daunting undertaking! The good news is that searching for rare plants is exciting, fun and rewarding! The local chapter and state-wide coordinated trips are often a combination of local rare-plant experts and less experienced native plant lovers who form a team to learn details about recognizing the targeted plants and then fanning out over the landscape finding things that one person alone would never have seen.

To join a Rare Plant Treasure Hunt keep an eye on your local chapter newsletter or visit the statewide CNPS webpage for RPTH news. Statewide and local trips will begin to be announced May 1st. If you want to be included on the statewide RPTH mailing list or create your own RPTH trip, email Steve at .

Desert RPTH Finds Rare Species

Spermolepis infernensisThe first statewide coordinated RPTH was conducted in Anza Borrego Desert State Park on March 31st looking for a newly described little carrot-family (Apiaceae) annual - Spermolepis infernensis.  This plant had only been collected four times and was never correctly recognized as a unique rare plant until 2012. Local experts Larry Hendrickson and Tom Chester prioritized the search areas and after a lot of searching a moderately thriving population was found on park property! Searches are continuing on similar habitat throughout the Borrego Valley. Hopefully all RPTHs will be similarly successful this year.

El Dorado Chapter's First RPTH of 2016

El Dorado RPTHCNPS Chapters and individuals often lead their own Rare Plant Treasure Hunts. In February, El Dorado Chapter members Annie Walker and Debra Ayres lead a group that hunted for a certain dry land sedge peculiar to gabbro and serpentine soils. This sedge, Carex xerophila, was recently (2014) described formally by Lawrence Janeway of the CSU Chico Herbarium and two other West Coast botanists. Associated with the sedge, they noted many of the other rare species of the Pine Hill rare plant complex: Ceanothus roderickii (in bud); Calystegia stebbinsii, Wyethia reticulata, Chlorogalum grandiflorum, Crocanthemum sp., and Packera layneae.

The RPTHers assembled at a small Preserve known as 50 at 50, and found the type locality of their target species after walking down a dirt frontage road at Highway 50. The whole group then surveyed down dirt road and found several more dense groupings of our sedge. Treasure hunters also made short forays into the thick chaparral to discover the sedge was not hiding in the shrubs and hunted along a fire line likely constructed during a 2007 fire on the property. The sedge seems to crave sunshine and human-caused disturbance on gabbro soils. It seemingly does not occur within mature chaparral, likely due to shading. Its absence on the burned site may be due to its absence there before the fire under the dense shrub canopy, or inability to survive fire (via deep rhizomes or buried seed).

At the end of the day, the RPTHers reported to the BLM Manager of the Pine Hill Preserves, Graciela Hinshaw, and her intern, Mia Dawson, about the problems observed with weed and vehicle disturbance on the property.  An observation report to the CalWeedMapper is pending.

Professional Botanist Certification Now Available

It's official! For the first time anywhere in the United States, botanists can earn a certification as a capable and responsible professional from a body of their peers. Certification will formally recognize those who have a high level of knowledge and experience in the field of botanical consulting in California. Certification is offered at two levels: one for the professional botanist who works primarily in the field conducting surveys of project sites (Field Botanist), and another for those who have demonstrated additional abilities to report on and analyze results of field surveys (Consulting Botanist). Certification will be awarded to those who successfully pass examinations and agree to abide by a professional code of ethics.

This project has been developed by CNPS in collaboration with numerous botanical groups and organizations in California, including the California Botanical Society, Northern California Botanists, Southern California Botanists, University of California, Berkeley Jepson Herbarium, and the California Department of Fish and Wildlife, among others.

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.
