Filetype[PDF-540.80 KB]


  • Description:
    A 5-year review is a periodic analysis of a species’ status conducted to ensure that the listing classification of a species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants (List) (50 CFR 17.11 – 17.12) is accurate. The 5-year review is required by section 4(c)(2) of the Endangered Species Act of 1973, as amended (ESA). The review was prepared pursuant to the joint National Marine Fisheries Service (NMFS) and U.S. Fish and Wildlife 5-year Review Guidance and template (NMFS and USFWS 2018). The NMFS Office of Protected Resources led the 5-year review with input from other NMFS regional offices and science centers. We updated information from the 5-year review completed in 2011 based on peer-reviewed publications, government and technical reports, conference papers, dissertations, and theses. We gathered information through September 2018. The information on the fin whale (Balaenoptera physalus) biology and habitat, threats, and conservation efforts was summarized and analyzed in light of the ESA section 4(a)(1) factors (see Section and the recovery criteria identified in the recovery plan (NMFS 2010; see Section 2.3.3) to determine whether a reclassification or delisting may be warranted (see Section 3.0).
