Main Hawaiian Islands Insular False Killer Whale Distinct Population Segment 5-Year Review

In November 2012, NOAA Fisheries listed the main Hawaiian Islands insular false killer whale distinct population segment as endangered under the Endangered Species Act. In April 2022, we published a 5-year review that determined that the main Hawaiian Islands insular false killer whale distinct population segment should remain listed as endangered. We will continue to reexamine the status once every 5 years to address new information available on this species. Our ultimate goal is to recover the main Hawaiian Islands insular false killer whale distinct population segment to the point where the species no longer needs protection under the Endangered Species Act.

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 is accurate.
