Vertical photographs were taken of the seals from an airplane flying directly above, as the seals rested on shore. Counts of the seals were then made from the photographic negatives. Seals were also counted at 27 resting sites by shore based observers. The California total was 19,622 seals which is higher than any previous census.

  • Pedro Point Headland Stewardship Project
    Preserving & Protecting the Open Spaces of Pacifica and Surrounding Areas. Land News Fall 2008 Vol. 7, No. 1 PLT Ventures into New Terrain: Pedro Point Headland Stewardship Project Michael C. Vasey Pedro Point Headland has been called Pacifica’s “Diamondhead.” Standing over six hundred feet high, its bold features punctuate Pacifica’s southern boundary, rising steeply above the long sweep of Linda Mar Beach and looming over Shelter Cove and San Pedro Rock. Pedro Point Headland contains some of the last, best native bunchgrass prairie along California’s coast and hosts diverse wildlife such as grey fox, bobcats, deer, peregrine falcons, and even mountain lions. It is also rich in historical significance as part of the old Ocean Shore Railroad and a site for “rum-running” during prohibition days. In 1992, the Pacifica Land Trust (PLT) was instrumental in preserving the Pedro Point Headland with the support of the California Coastal Conservancy, Cal-Trans, and the City of Pacifica. The Headland now serves as a premier part of Pacifica’s open space network. Over the years, the PLT has obtained grants of approximately $185,000 to conduct erosion control, weed removal, and re-vegetation efforts to improve the value of this open space gem. We also The PLT was instrumental in have worked diligently to ensure that this property is eventu- ally transferred to a public land manager. Within the past few preserving the Pedro Point years, the Golden Gate National Recreation Area committed to add Pedro Point Headland to its other major San Mateo Headland with the support County units such as Sweeney Ridge, Milagra Ridge, Mori of the California Coastal Point, and–most recently–Rancho Corral de Tierra.

  • SHORELINE PROTECTION TABLES (SP TABLES) for VESSEL TRAFFIC in CALIFORNIA’S MARINE WATERS (Tables Dated August 29, 2013)
    SHORELINE PROTECTION TABLES (SP TABLES) FOR VESSEL TRAFFIC IN CALIFORNIA’S MARINE WATERS (Tables Dated August 29, 2013) PURPOSE AND SCOPE The Shoreline Protection Tables (SP Tables) set forth planning requirements for shoreline protection for vessels in California’s marine waters. A vessel owner/operator shall demonstrate through contracts(s) or other approved means (see Sections 815.05(b) or 825.05(a)), the shoreline protection response resources necessary to protect each type of shoreline and all applicable sensitive sites as outlined in the appropriate SP Tables. Based on these Tables the owner/operators will be able to ascertain the type of equipment that must be available for the appropriate response strategies necessary to protect the shoreline types that could be affected. For the purpose of meeting the regulatory requirements, contracts for shoreline protection services can only be made with OSROs Rated by the Office of Spill Prevention and Response. The SP Tables are for vessels that transit in California’s marine waters. In addition, for the small harbors identified, a Small Harbor Table is included to define preparedness levels for these areas. The requirements set forth in these Tables are planning standards and may not reflect the exigencies of actual spill response. However, these are the standards that must be used to determine the amount of equipment and personnel that must be under contract or other approved means. The owner/operator is ultimately responsible for protecting the sensitive sites identified from the entire volume of an actual spill regardless of the planning volume. Skimming assets required to execute the strategies listed in the Tables will be included as part of the required on-water recovery capacity, as stipulated in CCR Sections 818.02(e) and 827.02(h), and should not be construed as requiring additional skimming capacity.

  • California Marine Life Protection Act Initiative Regional Profile of the North Central Coast Study Region May 7, 2007Draft
    California Marine Life Protection Act Initiative Regional Profile of the North Central Coast Study Region May 7, 2007Draft 1.0 Introduction The Marine Life Protection Act (MLPA) was signed into law in 1999. The MLPA directs the state to redesign California’s system of marine protected areas to increase its coherence and effectiveness in protecting the state’s marine life and habitats, marine ecosystems, and marine natural heritage, as well as to improve recreational, educational and study opportunities provided by marine ecosystems. To the extent possible, the system is to be designed and managed as a network. In August 2004, the California Resources Agency, California Department of Fish and Game (CDFG), and the Resource Legacy Fund Foundation signed a memorandum of understanding launching the MLPA Initiative and implementation of the MLPA in the central coast. Among other actions, the MLPA Initiative established the MLPA Blue Ribbon Task Force, the Master Plan Science Advisory Team (SAT), a statewide stakeholder interests group, and MLPA Initiative staff. A second memorandum of understanding, effective January 1, 2007, continues the public-private partnership for planning and implementation of marine protected areas (MPAs) in the north central coast. By December 2006 five key objectives were achieved by the MLPA Initiative: (1) a draft Master Plan Framework for MPAs was developed, (2) alternative proposals for MPAs in the central coast study region were developed and submitted to CDFG, (3) a strategy was recommended for long-term funding for MPA implementation and management, (4) a report was prepared with recommendations to increase coordination and collaboration among state and federal agencies with the authority to manage marine resources, and (5) a recommended executive order was submitted to secure agreement among state agencies to complete implementation of a statewide Master Plan for MPAs by 2011.

So it is fitting that the San Francisco Bay National Wildlife Refuge Complex plays that same role as a "gateway" to the U.S. Fish and Wildlife Service programs and the 530+ units of the National Wildlife Refuge System. Included in the San Francisco Bay NWR Complex are seven refuges, stretching from Monterey Bay to the San Francisco Bay Delta. This complex is a unique combination of habitats and wildlife species. The Don Edwards San Francisco Bay NWR in the South Bay has tidal marshes, vernal pools, and salt ponds. At the north end of the Bay is the San Pablo Bay NWR with estuaries and marsh habitat. The Farallon NWR, which lies thirty miles off the coast from the Golden Gate Bridge, is comprised of high rocky islands frequented by a host of seabirds, seals, and sea lions. A quiet upland habitat for the endangered Santa Cruz long-toed salamander can be found at the Ellicott Slough NWR just south of Santa Cruz. The Salinas River NWR just north of Monterey encompasses an area of pristine beach, dunes, and lagoon habitat. Found in the small pockets of native habitat at Antioch Dunes NWR are the endangered Antioch Dunes Evening Primrose, Contra Costa Wallflower and the Lange's Metalmark butterfly.

Linking seabird movements with environmental conditions over vast expanses of the world’s open ocean, however, remains difficult. Seabirds of the Order Procellariiformes (e.g., petrels, albatrosses, and shearwaters) depend largely on wind and wave energy for efficient flight. We present a new method for quantifying the movements of far-ranging seabirds in relation to ocean winds measured by the SeaWinds scatterometer onboard the QuikSCAT satellite. We apply vector correlation to evaluate how the trajectories (ground speed and direction) for five procellariiform seabirds outfitted with satellite transmitters are related to ocean winds. Individual seabirds (Sooty Shearwater, Pink-footed Shearwater, Hawaiian Petrel, Grey-faced Petrel, and Black-footed Albatross) all traveled predominantly with oblique, isotropic crossing to quartering tail-winds (i.e., 105° to 165° in relation to birds’ trajectory). Entire track line trajectories were significantly correlated with co-located winds. Greatest correlations along 8-day path segments were related to wind patterns during birds’ directed, long-range migration (Sooty Shearwater) and movements associated with mega-scale meteorological phenomena, including Pacific Basin anticyclones (Hawaiian Petrel, Grey-faced Petrel) and eastward- propagating north Pacific cyclones (Black-footed Albatross).
