Petition to List the Upper Klamath-Trinity River Chinook Evolutionarily Significant Unit as Threatened or Endangered under the Endangered Species Act

Petitioners Karuk Tribe and Salmon River Restoration Council request that the National Marine Fisheries Service (NMFS) reconsider its decision to deny a previous petition from Environmental Protection Information Center et al. to list as threatened or endangered the Upper Klamath-Trinity River (UKTR) Chinook Evolutionarily Significant Unit (ESU) ( Oncorhynchus tshawytscha) or, alternatively, create a new ESU to describe Klamath Spring Chinook (Center for Biological Diversity et al. 2011).
