Sei Whale 5-Year Review

Under section 4(c)(2) of the Endangered Species Act (ESA), we are required to conduct a review of all listed species at least once every 5 years to assess whether the current listing status remains accurate. The sei whale was listed as endangered in 1970 (35 FR 8491) under a precursor to the ESA. In 2018, we initiated the 5-year review. The NMFS Office of Protected Resources led the 5-year review with input from NMFS regional offices and science centers. The 5-year review is based on the best available data through June 2021. We concluded that no change to the listing status of the sei whale is warranted at this time.
