Listing Endangered or Threatened Species; 90-Day Finding on a Petition To Delist the Snake River Fall-Run Chinook Salmon Evolutionarily Significant Unit

We, the National Marine Fisheries Service (NMFS), announce a 90-day finding on a petition to delist the Snake River fall-run Chinook salmon (Oncorhynchus tshawytscha) (Snake River fall-run Chinook) Evolutionarily Significant Unit (ESU) under the Endangered Species Act (ESA). The Snake River fall-run Chinook ESU was listed as threatened under the ESA in 1992. We reviewed the status of the ESU in 2005 and again in 2011 and concluded that the ESU's classification as a threatened species remained appropriate. We find that the petition presents substantial scientific information indicating that the petitioned action may be warranted. We hereby initiate a status review of the Snake River fall-run Chinook ESU to determine whether the petitioned action is warranted. To ensure that the status review is comprehensive, we are soliciting scientific and commercial information pertaining to this species.
