Listing Endangered and Threatened Species; Initiation of 5-Year Reviews for 27 Evolutionarily Significant Units and Distinct Population Segments of Pacific Salmon and Steelhead

الملخص

We, NMFS, announce 5-year reviews of 16 evolutionarily significant units (ESUs) of Pacific salmon (Oncorhynchus sp.) and 11 distinct population segments (DPSs) of steelhead (Oncorhynchus mykiss) under the Endangered Species Act of 1973, as amended (ESA). The purpose of the review is to ensure the accuracy of the listing classifications of these salmonids. On June 28, 2005, NMFS issued final listing determinations for 16 ESUs of Pacific salmon and on January 5, 2006 for ten DPSs of steelhead. We will also complete a 5-year review of Puget Sound steelhead listed on May 11, 2007. The 5-year reviews will be based on the best scientific and commercial data available at the time of the reviews; therefore, we request submission of any such information on these ESUs and DPSs that has become available since the listing determinations in 2005, 2006, and 2007. Based on the results of these 5-year reviews, we will make the requisite determinations under the ESA.
