Endangered and Threatened Species; Initiation of 5-Year Review for Southern Resident Killer Whales

We, NMFS, announce a 5-year review of Southern Resident killer whales (Orcinus orca) under the Endangered Species Act of 1973, as amended (ESA). The purpose of these reviews is to ensure that the listing classification of a species is accurate. The 5-year review will be based on the best scientific and commercial data available at the time of the review; therefore, we request submission of any such information on Southern Resident killer whales that has become available since their original listing as endangered in November 2005 or since the previous 5-year review completed in 2011. Based on the results of this 5-year review, we will make the requisite determination under the ESA.
