    Occurrence of Hawksbill Turtles, Eretmochelys imbricata (Reptilia: Cheloniidae), near the Baja California Peninsula, Mexico.

    From 1997 to 2001 the occurrence of hawksbill turtles (Eretmochelys imbricata) was characterized at neritic foraging habitats along the Pacific coast of the Baja California Peninsula and in the Gulf of California, Mexico, through inwater capture of live turtles and searches for dead carcasses. We recorded a total of 27 hawksbill turtles: 14 (four live-captured and 10 strandings [dead turtles]) along the Pacific coast of Baja California and 13 (seven live-captured and six strandings) in the Gulf of California. The range of straight carapace lengths for hawksbill turtles from the Pacific and the Gulf of California was 35.4 to 52.5 cm (mean 1/4 42.5 cm) and 34.4 to 74.2 cm (mean 1/4 48.0 cm), respectively. Although hawksbills are uncommon in coastal neritic habitats near Baja California, their continued presence indicates that this region should be included as a focus area for future conservation efforts.

    Biology and conservation of sea turtles in Baja California, Mexico.

    I studied the in-water anthropogenic impacts on sea turtles, origins of sea turtles
    on foraging and developmental areas, their migration routes, and described regionally
    appropriate conservation needs. Sea turtles inhabiting Baja California waters originate on
    distant beaches in Japan, Hawaii, and southern Mexico. Results from genetic analyses,
    flipper tagging and satellite telemetry indicate loggerhead turtles (Caretta caretta)
    feeding along Baja California’s coast are born in Japan and make a transpacific
    developmental migration of more than 20,000 km, encompassing the entire North Pacific
    Ocean and that East Pacific green turtles (Chelonia mydas) originate on and return to
    rookeries in Michoacan, and the Islas Revillagigedo, Mexico. Hawksbill turtles
    (Eretmochelys imbricata), once the target of a lucrative fishery for their shell, are now
    extremely scarce and only juveniles were encountered. The region’s importance to the
    biology of sea turtles, regionally and Pacific-wide, warrants urgent conservation action.

    Recovery Plan for U.S. Pacific Populations of the Hawksbill Turtle (Eretmochelys imbricata).

    The National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (FWS) share responsibilities at the Federal level for the research, management, and recovery of Pacific marine turtle populations under U.S. jurisdiction. To accomplish the drafting of this recovery plan, NMFS appointed a team of professional biologists experienced with marine turtles in the Pacific region. This document is one of six recovery plans (one for each of the five species plus one for the regionally important population of the East Pacific green turtle).
