  • Introduction
    INTRODUCTION Although much of the San Francisco Bay Region is densely populated and industrialized, many thousands of acres within its confines have been set aside as parks and preserves. Most of these tracts were not rescued until after they had been altered. The construction of roads, the modification of drainage patterns, grazing by livestock, and the introduction of aggressive species are just a few of the factors that have initiated irreversible changes in the region’s plant and animal life. Yet on the slopes of Mount Diablo and Mount Tamal- pais, in the redwood groves at Muir Woods, and in some of the regional parks one can find habitats that probably resemble those that were present two hundred years ago. Even tracts that are far from pristine have much that will bring pleasure to those who enjoy the study of nature. Visitors to our region soon discover that the area is diverse in topography, geology, cli- mate, and vegetation. Hills, valleys, wetlands, and the seacoast are just some of the situa- tions that will have one or more well-defined assemblages of plants. In this manual, the San Francisco Bay Region is defined as those counties that touch San Francisco Bay. Reading a map clockwise from Marin County, they are Marin, Sonoma, Napa, Solano, Contra Costa, Alameda, Santa Clara, San Mateo, and San Francisco. This book will also be useful in bordering counties, such as Mendocino, Lake, Santa Cruz, Monterey, and San Benito, because many of the plants dealt with occur farther north, east, and south. For example, this book includes about three-quarters of the plants found in Monterey County and about half of the Mendocino flora.

Wallace California Botanic Garden [formerly Rancho Santa Ana Botanic Garden], 1500 North College Avenue, Claremont, California 91711 ([email protected]) abstract An account of the extent, diversity, and importance of the Californian collections of Thomas Coulter in the herbarium (TCD) of Trinity College, Dublin, Ireland, is presented here. It is based on examination of collections in TCD, several other collections available online, and referenced literature. Additional infor- mation on historical context, content of herbarium labels and annotations is included. Coulter’s collections in TCD are less well known than partial duplicate sets at other herbaria. He was the first botanist to cross the desert of southern California to the Colorado River. Coulter’s collections in TCD include not only 60 vascular plant specimens previously unidentified as type material but also among the first moss andmarine algae specimens known to be collected in California. A list of taxa named for Thomas Coulter is included.

  • Serpentine Endemic Occupancy Project – 2019 Field Season Report
    Serpentine Endemic Occupancy Project – 2019 Field Season Report Rachel Kesel David Greenberger Andrea Williams Michael Sturtevant Elizabeth Neill Introduction Serpentine barrens are found throughout much of the One Tam area of focus. These rocky balds are the harshest of all serpentine communities. They range in size and are characterized by their island-like nature: sparse vegetation, and large amount of exposed serpentinite rock. California has the richest concentration of serpentine flora in the temperate zone and many of these species are endemic to the San Francisco Bay Area. High concentrations of rare and endemic plant species make these habitats important targets for monitoring. Population dynamics of the rare annual plants in these habitats are poorly understood. One Tam has over 39,000 acres of protected open space, with serpentine barrens occurring on Marin Municipal Water District (MMWD), Marin County Parks (MCP) and Mount Tamalpais State Park (State Parks) lands. Vegetation mapping efforts indicate that, in aggregate, there may be over 30 acres of serpentine barren habitat across more than 85 discreet patches. Serpentine barrens have also been found in areas which were mapped to non-serpentine plant communities, indicating that vegetation maps available as of 2019 have not identified all barren habitats. In 2016, One Tam launched a pilot project aimed at developing a monitoring design that allows staff to take a feasible sample of the barren patches each year to assess the overall health of rare plants on those habitats. The pilot began with the survey of 14 serpentine barrens in the Carson Ridge region of Mount Tamalpais on land owned by MMWD.

Of the gross project site area, 0.22 acre lies under the East Sir Francis Drake Boulevard right-of-way and 0.16 acre lies under the Lincoln Village Circle right-of-way, leaving a net project site area of approximately 10.295 acres. PROJECT DESCRIPTION The former Larkspur Wastewater Treatment Plant was purchased and operated by the Sanitary District No. 1 of Marin County (District) from 1948 to 1985; the facility was decommissioned in 1985 and demolished in 1998 and 1999. Crushed concrete from the demolition was mixed with soil and used as engineered backfill onsite. The site received a “no further action” letter from the Department of Toxic Substances Control in 2006, but subsequent testing from 2006 to 2008 indicated the presence of elevated concentrations of polychlorinated biphenyls (PCBs) in site media.

  • Mapping Plant Biodiversity Hotspots at the County Scale
    MAPPING PLANT BIODIVERSITY HOTSPOTS AT THE COUNTY SCALE: A NEW TOOL FOR ESTABLISHING RESOURCE CONSERVATION STRATEGIES A Thesis Presented to The Faculty of California Polytechnic State University San Luis Obispo In Partial Fulfillment Of the Requirements for the Degree Master of Science in Biological Sciences By Krisite Haydu June, 2012 © 2012 Kristie Haydu ALL RIGHTS RESERVED ii TITLE: Mapping Plant Biodiversity Hotspots at the County Scale: A New Tool for Establishing Resource Conservation Strategies AUTHOR: Kristie Haydu DATE SUBMITTED: June, 2012 COMMITTEE CHAIR: Matt Ritter, Ph.D. COMMITTEE MEMBER: David Keil, Ph.D. COMMITTEE MEMBER: David Yun, MS, GISP iii ABSTRACT Mapping Plant Biodiversity Hotspots at the County Scale: A New Tool for Establishing Resource Conservation Strategies Kristie Haydu Myers first identified the world’s 25 biodiversity hotspots and pioneered innovative ideas about the usefulness of biodiversity models for establishing long-term resource conservation strategies at global scales. Since Myers, most of the subsequent studies using hotspot science for biodiversity modeling have used large spatial scales like countries, provinces or states, and other biogeoraphic regions. The California Floristic Province continues to be one of the recognized global biodiversity hotspots. Our study site, San Luis Obispo County is within this hotspot and we created a map of plant biodiversity hotspots at the county scale using GIS technology. We wanted to determine the effectiveness and applicability of biodiversity hotspot mapping at this scale with anticipation that the map will serve as a new tool for establishing long-term resource conservation strategies in the County. Our plant biodiversity hotspot map is based on distribution data collected from herbarium specimens of San Luis Obispo County’s rare flora.
