Description:"The Green Turtle Status Review Team (SRT) has undertaken a review consistent with section 4(a)(1) of the Endangered Species Act (ESA), using the best available scientific information. The SRT assessed the green turtle population structure globally in order to determine whether the green turtle could be listed as one or more Distinct Population Segments (DPSs). After determining that DPSs could be identified and identifying potential DPSs, the SRT assessed the risk of extinction for each potential DPS using a structured decision-making process that combined analysis of large amounts of empirical data with expert opinion. Extinction risk probabilities were considered based on six different critical assessment elements, including four indicators of "Viable Turtle Populations" (abundance, productivity, spatial structure, diversity / resiliency), as well as an assessment of threats and conservation efforts. The SRT report drew conclusions for each potential DPS regarding extinction risk (using quasiextinction thresholds) under current management regimes. In doing this, the SRT considered the six critical assessment elements listed above based on the assumption that ESA protective measures would continue into the future. The SRT was not asked to, and did not, speculate on extinction risk under a theoretical scenario in which the green turtle was not listed under the ESA. The SRT also was not asked to assess the role of the ESA in the conservation of the species following listing. The SRT did not make any listing recommendations regarding status under the ESA; those listing determinations will be made separately by a management team. When making its listing determination, the management team will rely on the SRT analysis and report as well as any other management considerations and additional information, including its assessment of increased risk to the species due to inadequacy of regulatory mechanisms under a scenario without ESA protections where they apply"--Preface.
