    SECTION 3.4 BIOLOGICAL RESOURCES 3.4- BIOLOGICAL RESOURCES 3.4 BIOLOGICAL RESOURCES This section discusses the existing sensitive biological resources of the San Francisco Bay Estuary (the Estuary) that could be affected by project-related construction and locally increased levels of boating use, identifies potential impacts to those resources, and recommends mitigation strategies to reduce or eliminate those impacts. The Initial Study for this project identified potentially significant impacts on shorebirds and rafting waterbirds, marine mammals (harbor seals), and wetlands habitats and species. The potential for spread of invasive species also was identified as a possible impact. 3.4.1 BIOLOGICAL RESOURCES SETTING HABITATS WITHIN AND AROUND SAN FRANCISCO ESTUARY The vegetation and wildlife of bayland environments varies among geographic subregions in the bay (Figure 3.4-1), and also with the predominant land uses: urban (commercial, residential, industrial/port), urban/wildland interface, rural, and agricultural. For the purposes of discussion of biological resources, the Estuary is divided into Suisun Bay, San Pablo Bay, Central San Francisco Bay, and South San Francisco Bay (See Figure 3.4-2). The general landscape structure of the Estuary’s vegetation and habitats within the geographic scope of the WT is described below. URBAN SHORELINES Urban shorelines in the San Francisco Estuary are generally formed by artificial fill and structures armored with revetments, seawalls, rip-rap, pilings, and other structures. Waterways and embayments adjacent to urban shores are often dredged. With some important exceptions, tidal wetland vegetation and habitats adjacent to urban shores are often formed on steep slopes, and are relatively recently formed (historic infilled sediment) in narrow strips.

Center for Ecosystem Management and Restoration CONTRA COSTA COUNTY Marsh Creek Watershed Marsh Creek flows approximately 30 miles from the eastern slopes of Mt. Diablo to Suisun Bay in the northern San Francisco Estuary. Its watershed consists of about 100 square miles. The headwaters of Marsh Creek consist of numerous small, intermittent and perennial tributaries within the Black Hills. The creek drains to the northwest before abruptly turning east near Marsh Creek Springs. From Marsh Creek Springs, Marsh Creek flows in an easterly direction entering Marsh Creek Reservoir, constructed in the 1960s. The creek is largely channelized in the lower watershed, and includes a drop structure near the city of Brentwood that appears to be a complete passage barrier. Marsh Creek enters the Big Break area of the Sacramento-San Joaquin River Delta northeast of the city of Oakley. Marsh Creek No salmonids were observed by DFG during an April 1942 visual survey of Marsh Creek at two locations: 0.25 miles upstream from the mouth in a tidal reach, and in close proximity to a bridge four miles east of Byron (Curtis 1942).

  • Planning for Native Oyster Restoration in San Francisco Bay. Final Report to California Coastal Conservancy Agreement
    Planning for Native Oyster Restoration in San Francisco Bay Final Report to California Coastal Conservancy Agreement # 05-134 Edwin Grosholza, Jim Mooreb, Chela Zabina, Sarikka Attoea and Rena Obernoltea aDepartment of Environmental Science and Policy University of California, Davis bCalifornia Department of Fish and Game Funding provided by the California Ocean Protection Council Introduction Historically, native Olympia oysters Ostreola conchaphila (=Ostrea lurida) (Turgeon et al. 1998) were an abundant and ecologically important part of the fauna in West Coast estuaries and an important fishery (Barnett 1963, Baker 1995). Unfortunately, the popularity of the fishery that began in the 1850s resulted in the complete collapse of native oyster populations along the west coast of the U.S. during the late 19th and early 20th centuries (Barnett 1963, Baker 1995). Not only was the fishery lost, but so were the key ecosystem services provided by native oysters. Studies of oysters in estuaries in the eastern U.S. have shown that native oyster reefs (Crassostrea virginica) act as a “foundation species” by creating a refuge from predators and physical stress as well as a food source resulting in increased local diversity of fishes and invertebrates (Zimmerman 1989, Lenihan 1999, Micheli and Peterson 1999, Lenihan et al. 2001). In the largely unstructured, soft-sediment habitats of West Coast estuaries, aggregations of native oysters were likely to have provided similar functions and have been shown to increase invertebrate species richness (Kimbro and Grosholz 2006). The introduction of exotic Pacific oysters (Crassostrea gigas) from Asia in the early 20th century provided a successful replacement for the native oyster fishery.

The Bay Plan was prepared by the Commission over a three-year period pursuant to the McAteer-Petris Act of 1965 which established the Commission as a temporary agency to prepare an enforceable plan to guide the future protection and use of San Francisco Bay and its shoreline. In 1969, the Legislature acted upon the Commission’s recommendations in the Bay Plan and revised the McAteer-Petris Act by designating the Commission as the agency responsible for maintaining and carrying out the provisions of the Act and the Bay Plan for the protection of the Bay and its great natural resources and the development of the Bay and shore- line to their highest potential with a minimum of Bay fill.

Trails and greenways provide the facilities for these activities. Our surveys of Californian’s recreational use patterns over the years have shown that our variety of trails, from narrow back-country trails to spacious paved multi-use facilities, provide experiences that attract more users than any other recreational facility in California. Th e increasing population and desire for trails are increasing pressures on the agencies charged with their planning, maintenance and management. As leaders in the planning and management of all types of trail systems, California State Parks is committed to assisting the state’s recreation providers by complying with its legislative mandate of recording the progress of the California Recreational Trails Plan. During the preparation of this progress report, input was received through surveys, two California Recreational Trails Committee public meetings and a session at the 2011 California Trails and Greenways Conference. Preparation of this progress Above: Director Ruth Coleman report included extensive research into the current status of the 27 California Trail Corridors, determining which of these corridors need administrative, funding or planning assistance. Research and public input regarding the Plan’s twelve Goals and their associated Action Guidelines have identifi ed both encouraging progress and areas where more attention is needed.

  • Harbor Seal Annual Report 2005
    Harbor Seal Monitoring at Point Reyes National Seashore and Golden Gate National Recreation Area Annual Report 2005 Prepared by: Melanie Vanderhoof and Sarah Allen 1 Introduction Harbor seals (Phoca vitulina richardii) are the dominant and only year round resident pinniped at Point Reyes, California. The Point Reyes seal population represents the largest concentration of harbor seals in the State of California, other than the Channel Islands, accounting for 20% of the mainland breeding population (Lowry and Carretta 2003). Much of the Point Reyes coastal zone remains fairly pristine and provides excellent marine and terrestrial habitat for seals to rest, molt feed and breed where human encroachment is minimal. Long-term monitoring studies of harbor seals have been conducted at selected colonies at Point Reyes since 1976 (Allen et al. 1989, Sydeman and Allen 1999, Allen et al. 2004). The objectives of monitoring are to 1) detect changes in population numbers, 2) detect changes in reproductive success and 3) identify anthropogenic or environmental factors that might affect population status and trends. The monitoring objectives and protocol are described in detail in Hester et al. (draft report). The information presented here is a summary of the data collected during the 2005 breeding and molting seasons, March- July. Summary data collected as part of a region-wide survey effort including adjacent areas (San Francisco Bay, San Mateo County and Sonoma County) where NPS surveys were conducted in 2005 in conjunction with other agencies and organizations are also presented.
