The greenback cutthroat trout (Oncorhynchus clarki stomias) is federally listed as threatened under provisions of the Endangered Species Act of 1973. Listed species require a 5-year status review be performed to ensure that the listing classification of a species is current. This capstone project compiled and researched all readily available information on the species to aid the United States Fish and Wildlife Service in completing an official 5-year Review. Information reviewed included the species' biology, population trends, habitat, threats, and other relevant information. The results of this status review indicated that the species should remain listed as threatened. In addition, 12 recommendations were identified during this study that will assist with the recovery and eventual delisting of the fish.
