Yerba Buena Chapter – CNPS PROGRAMS Everyone is welcome to attend membership meetings in the Recreation Room of the San Francisco YERBA County Fair Building (SFCFB) at 9 th Avenue and Lincoln Way in Golden Gate Park. The #71 and #44 buses stop at the building. The N-Judah, #6, #43, and #66 lines stop within 2 blocks. Before our BUENA programs, we take our speakers to dinner at Chang’s Kitchen, 1030 Irving Street, between 11 th and 12 th Avenues. Join us for good Chinese food and interesting conversation. Meet at the restaurant at 5:30 pm. RSVP appreciated but not required - call Jake Sigg at 415-731-3028 if you wish to notify. September 5, THURSDAY, 7:30 pm The Ecology and Plants of the Farallon Islands Speaker: Peter Pyle The Farallon Islands, part of the City and County of San Francisco, is a National Wildlife Refuge located NEW S 27 miles west of the Golden Gate Bridge. Cold ocean currents and other environmental factors there lead to high ocean productivity and a thriving marine wildlife ecology. Biologists working for PRBO/Point THE YERBA BUENA Blue Conservation Science and the U.S. Fish and Wildlife Service have resided on Southeast Farallon Island since April 1968, studying all aspects of the island's environment and ecology. Peter Pyle spent CHAPTER OF THE over 2,100 nights at the island's biological station in 1980-2003, primarily focused on birds, marine CALIFORNIA mammals, and white sharks, but also dabbling in everything else including bats, dragonflies, salamanders, NATIVE PLANT butterflies, crickets, mushrooms, and, yes, even the island's unique fog-whipped flora. Peter's talk will SOCIETY FOR briefly cover the ecology and conservation of the islands' marine vertebrates. He will then present a history of botanical investigation on Southeast Farallon Island, his first successful attempt to key out a SAN FRANCISCO plant, and information on the ca. 45 each of indigenous and non-native species that have been recorded AND NORTHERN there. He will consider everything from the dominant and endemic "Farallon weed" ( Lasthenia maritima ), SAN MATEO COUNTY to plants that have been recorded only once, to efforts at invasive species removal. He will also bring up for discussion the possible effects that the proposed eradication of invasive house mice may have on Vol. 33 No.3 September 2019 the island's flora. Peter Pyle has worked as an ornithologist and marine biologist throughout the Pacific. He is now an CONTENTS identification specialist and consultant for the Greater Farallones National Marine Sanctuary's Beach Programs – page 1 Watch program and a staff biologist for the Institute for Bird Populations in Point Reyes Station. He is Field Trips – page 2 a Research Associate both at the California Academy of Sciences and the B.P. Bishop Museum, Honolulu. Activities – page 2 To date he has authored or co-authored over 180 papers in scientific journals and four books, and has Ode to Coyote Bush – page 3 described a new species of shearwater ( Puffinus bryani ), naming it after his grandfather, Edwin Bryan. Volunteer Spotlight – page 3 Mountain Journal – page 4 October 3, THURSDAY, 7:30 pm NO PROGRAM in December Focus on Rarities – pages 5,6 Mapping California’s Important Plant Areas Habitat Restoration – page 6 Speaker: Sam Young Chapter News – page 7 California is a globally significant biodiversity hotspot. With roughly 6,500 native plant taxa, the Golden State boasts similar botanical diversity to Japan and New Zealand. Its mild climates and rugged landscapes have also made California a highly desirable place to live, with a population close to 40 million people and growing. Demands for housing, habitat loss, and a changing climate are placing increasing pressure on California’s unique flora. Regional planning efforts are being developed to meet the demands of an increasing population. It is essential that botanical data and conservation values be well represented in these efforts. The CNPS Important Plant Area (IPA) Program seeks to identify the most important areas for preserving California’s botanical biodiversity heritage. Identification and protection of IPAs have been called out as essential components for biodiversity conservation both at home through the California Biodiversity Initiative and on the world stage through the Global Plant Conservation Strategy. Join Sam Young, CNPS IPA Manager, for a discussion on California’s plant biodiversity, IPA methods, and strategies for realizing IPA conservation goals. November 7, THURSDAY, 7:30 pm Management of the Rare Plants and Butterflies of San Bruno Mountain Speaker: Hannah Ormshaw San Bruno Mountain State and County Park is a habitat island amidst a sea of urbanization, and is home to a variety of rare, threatened, and endangered plant and wildlife species - some of which occur only in this park. This talk will outline recent efforts to map and catalogue rare plant populations, describe the critical habitat requirements for the four protected butterfly species found in the park, and discuss the ongoing efforts for habitat management for the benefit of these protected species. Hannah Ormshaw is a Natural Resource Specialist for the San Mateo County Parks Department, and is the primary staff person involved in the implementation and oversight of the San Bruno Mountain Habitat Conservation Plan. She is regularly out on the mountain monitoring butterflies, Marah oreganus doing vegetation surveys and mapping, and coordinating habitat management activities. She is coast manroot also the senior biologist for all natural resource management activities in all county parks. FIELD TRIPS Members and non-members are encouraged to attend these FREE walks. Signups generally not required—just meet at the specified place and time. If rain or high wind is forecast, we recommend checking with the contact (listed at the end of the trip description) a couple of hours before the trip. Aristolochia californica dutchman’s pipe October 19, SATURDAY 10am - 1pm by Margaret Kemp San Bruno Mountain: Dairy Ravine-Cable Ravine Leader: Doug Allshouse These two north-facing ravines form most of the area above the parking lot opposite the park entrance. Their names allude to dairy ranching and to cables that descend from the communication towers on the summit. The two ravines share similar plant communities that are dotted with eucalyptus plantings threatening endangered butterfly habitat. To explore both ravines we’ll walk the Eucalyptus Loop to the Dairy Ravine and Summit Trails ascending to the mountain’s summit. Then it’s on to Kamchatka Point to see four species in Ericaceae, the Heather family, featuring three species that are endemic to San Bruno Mountain. The first two are San Bruno Mountain manzanita ( Arctostaphylos imbricata ) and a pretty form of bearberry manzanita ( A. uva-ursi forma suborbiculata ). We’ll see California huckleberry ( Vaccinium ovatum ), and a pending third endemic surprise. The $6 entry fee is payable by cash or credit/debit card at the pay station. Meet at the parking lot on the other side of Guadalupe Canyon Parkway. Turn right at the stop sign just past the kiosk and follow the road under the parkway. Due to the marine influence the mountain offers box-of-chocolates weather so bring layers. Heavy rain cancels. Contact Doug at [email protected], call or text 415-269-9967 if you have questions. ACTIVITIES SEMI-ANNUAL FOUNTAIN THISTLE WORK PARTY October 26, SATURDAY, 10am - 12:30pm Intersection of I-280 and Hwy. 92, San Mateo Our work at this site is a restoration success story.

HARRIS University of Massachusetts, Fernald Hall, 270 Stockbridge Road, Amherst, MA 01003 EARL B. ALEXANDER 1714 Kasba Street, Concord, CA 94518 ABSTRACT. Serpentine outcrops are model habitats for geoecological studies. While much attention has been paid to serpentine outcrops worldwide, the literature on eastern North American serpentine and associated biota is scant. This review examines the available literature, published and unpublished, on geoecological studies conducted on serpentine in eastern North America, from Newfoundland through Que´bec and New England south to Alabama. Most serpentine outcrops in the region have been mapped, but there have been few intensive mineralogical and pedological investigations. The limited soil analyses available suggest elevated levels of heavy metals such as Ni, near-neutralpH values, and Ca:Mg ratios , 1, characteristic of serpentine soils worldwide. Botanical studies to date have largely focused on floristic surveys and the influence of fire exclusion and grazing on indigenous vegetation. To date, 751 taxa of vascular plants belonging to 92 families have been reported from serpentine outcrops in the region. Two taxa, Agalinis acuta and Schwalbea americana, are federally endangered in the United States while many others are listed as rare, endangered, or imperiled in one or more states or provinces.

  • Summary Information
    Summary Information Marin Audubon Society Petaluma Marsh Expansion Project − monitoring and secondary test site for the integrated regional wetland monitoring project Amount sought: $235,000 Duration: 12 months Lead investigator: Dr. Stuart Siegel, Wetlands and Water Resources Short Description This project will monitor and evaluate the Petaluma Marsh Expansion Project (PMEP),(ERP Project # ERP−98−F13). This project will monitor this marsh as a secondary site within the Integrated Regional Wetland Monitoring Project (IRWM). This project will: 1) evaluate the underlying management question, how are ecosystem restoration efforts throughout the region affecting ecosystem processes at different scales; and (2) through application of adaptive monitoring strategy concepts, prepare for subsequent longer−term monitoring. Executive Summary The restoration action we propose to monitor and evaluate is the Petaluma Marsh Expansion Project (PMEP), which is funded by the CALFED Ecological Restoration Program (ERP Project # ERP−98−F13) and CalTrans and owned and operated by the Marin Audubon Society (MAS). We want to monitor this marsh as a secondary site within the Integrated Regional Wetland Monitoring Project (IRWM). The project site is next to the ancient Petaluma Marsh, on the San Antonio Creek near the Marin/Sonoma County borders. The project involves restoring approximately 110 acres of diked baylands back to tidal marsh by breaching/lowering levees, excavating tidal channels, planting salt marsh vegetation, and more. The goals of the restoration project are (1) to increase tidal marsh habitat in the North Bay, which has lost most of its historic tidal marshes, and (2) to provide habitat for special−status species such as the California clapper rail and salt marsh harvest mouse.

  • The Lasthenia Californica Story: It Started with Flavonoids
    Bohm & Rajakaruna. 2006. Published in Natural Product Communications. 11:1013-1022. The Lasthenia californica Story: It Started with Flavonoids Bruce A. Bohma* and Nishanta Rajakarunab a3685 W. 15th Avenue, Vancouver, B .C. V6R 2Z6 Canada bCollege of the Atlantic, Bar Harbor, ME 04609, USA [email protected] Dedicated to Professor E. Wollenweber on the occasion of his 65th birthday. Our laboratory’s study of Lasthenia (Asteraceae) began with an examination of flavonoid profiles of all species of the genus. The finding of two distinct flavonoid races within the L. californica complex led us to investigate environmental factors that might have been responsible for selection of these particular forms. Data were gathered on soil chemistry, allozyme variation, breeding biology, the effect of water stress on plant growth, and ion uptake physiology. In conjunction with workers at other institutions, DNA studies were undertaken to determine evolutionary relationships between the two races. These studies led to the recognition that racial differences had arisen in parallel in two phylogenetically independent lineages. These results are discussed in terms of the evolution of edaphic (soil type) races, and the possible usefulness of the system as a model for future studies of parallel speciation in plants. Keywords: Lasthenia, edaphic races, serpentine soils, speciation, speciation model. Lasthenia is a small genus in Asteraceae that consists pools in the Central Valley of California, while others of as many as 21 species and subspecies, depending occur on serpentine-derived soils. Edaphic on taxonomic opinion, with a mainly western North specialization seems to be one of the major features American distribution but with a single species in of the genus and the Chilean species represent one of Chile.

  • Lessons on Evolution from the Study of Edaphic Specialization
    Bot. Rev. https://doi.org/10.1007/s12229-017-9193-2 Lessons on Evolution from the Study of Edaphic Specialization Nishanta Rajakaruna1,2,3 1 Biological Sciences Department, California Polytechnic State University, San Luis Obispo, CA 93407, USA 2 Unit for Environmental Sciences and Management, North-West University, Private Bag X6001, Potchefstroom 2520, South Africa 3 Author for Correspondence; e-mail: [email protected] # The New York Botanical Garden 2017 Abstract Plants adapted to special soil types are ideal for investigating evolutionary processes, including maintenance of intraspecific variation, adaptation, reproductive isola- tion, ecotypic differentiation, and the tempo and mode of speciation. Common garden and reciprocal transplant approaches show that both local adaptation and phenotypic plasticity contribute to edaphic (soil-related) specialization. Edaphic specialists evolve rapidly and repeatedly in some lineages, offering opportunities to investigate parallel evolution, a process less commonly documented in plants than in animals. Adaptations to soil features are often under the control of major genes and they frequently have direct or indirect effects on genes that contribute to reproductive isolation. Both reduced competitiveness and greater susceptibility to herbivory have been documented among some edaphic specialists when grown in ‘normal’ soils, suggesting that a high physiological cost of tolerance may result in strong divergent selection across soil boundaries. Interactions with microbes, herbivores, and pollinators influence soil specialization either by directly enhancing tolerance to extremes in soil conditions or by reducing gene flow between divergent populations. Climate change may further restrict the distribution of edaphic specialists due to increased competition from other taxa or, expand their ranges, if preadaptations to drought or other abiotic stressors render them more competitive under a novel climate.

  • Applying the Concept of Stewardship Responsibility in British Columbia
    technical subcommittee component report Applying the Concept of Stewardship Responsibility in British Columbia PREPARED BY: FRED L. BUNNELL, L. KREMSATER AND I. HOUDE FOR: THE BIODIVERSITY BC TECHNICAL SUBCOMMITTEE FOR THE REPORT ON THE STATUS OF BIODIVERSITY IN BC DECEMBER 2006 Applying the Concept of Stewardship Responsibility in British Columbia By: Fred L. Bunnell L. Kremsater I. Houde Prepared for: The Biodiversity BC Technical Sub Committee For the Report on the Status on Biodiversity in BC December 2006 Summary Lists of species at risk are designed primarily to provide an easily understood estimate of risk and extinction. The lists have become linked to decision-making processes, often in unhelpful ways. Unhelpful guidance can be reduced through the concept of responsibility. The broad concept of stewardship responsibility is simple: within a jurisdiction we should allocate greater effort to conserve species for which we have a greater proportion of the global population or range (responsibility). That is, other things being equal, a species having 70% of its population or range within British Columbia should receive greater conservation effort than a species having 2% of its range within the province. The concept is widely applied in international conservation efforts and can be adapted readily to a particular jurisdiction. For most species, responsibility is estimated from the proportion of occupied range occurring within British Columbia. The task is simple but tedious because a variety of sources are required for the vast majority of species. Estimating responsibility for ecosystems confronts a major challenge: there is far less agreement on what is the same ecosystem than on what is the same species.
