On February 27, 2018, the National Marine Fisheries Service (“Service”) published a 90-day finding on the Karuk Tribe and Salmon River Restoration Council’s (“Petitioners”) petition to list the Upper Klamath-Trinity Rivers Basin (“UKTR”) Chinook salmon (Oncorhynchus tshawtscha) evolutionarily significant unit (“ESU”) as endangered or threatened. Based on the information included in Petitioners’ filing, the Service found that listing the UKTR ESU as endangered or threatened under the Endangered Species Act (“ESA”) may be warranted.

Finally, the Service concluded that a 2017 genetic study of spring run and fall run Chinook salmon indicates that spring-run premature migration qualifies UKTR ESU as an evolutionarily significant unit under the Service’s evolutionarily significant unit policy.
