LISTED SPECIESAn endangered species is one that is in danger of extinction throughout all or a significant portion of its range. A threatened species is one that is likely to become endangered in the foreseeable future.
PROPOSED SPECIESTaxa for which the Fish and Wildlife Service or National Marine Fisheries Service has published a proposal to list as endangered or threatened in the Federal Register.
CANDIDATE SPECIESTaxa for which the Fish and Wildlife Service has sufficient biological information to support a proposal to list as endangered or threatened.
DELISTED SPECIESA species that has been removed from the Federal list of endangered and threatened wildlife and plants.
SPECIES OF CONCERNTaxa whose conservation status is of concern to the U.S. Fish and Wildlife Service (many previously known as Category 2 candidates), but for which further information is still needed. Such species receive no legal protection and use of the term does not necessarily imply that a species will eventually be proposed for listing.
MARINE & ANADROMOUS SPECIESThe National Marine Fisheries Service (NMFS) manages mostly marine and anadromous species, while the U.S. Fish and Wildlife Service manages the remainder of the listed species, mostly terrestrial and freshwater species.
MARINE TURTLE CONSERVATION AND MANAGEMENTAll six species of sea turtles occurring in the U.S. are protected under the Endangered Species Act of 1973. In 1977, NOAA Fisheries and the U.S. Fish and Wildlife Service signed a Memorandum of Understanding to jointly administer the Endangered Species Act with respect to marine turtles. NOAA Fisheries has the lead responsibility for the conservation and recovery of sea turtles in the marine environment and the U.S. Fish and Wildlife Service has the lead for the conservation and recovery of sea turtles on nesting beaches. For more information, see the NOAA Fisheries webpage on sea turtles.
GRAY WOLFOn February 27, 2008, the Service published a final rule that established a distinct population segment of the gray wolf (Canis lupis) in the northern Rocky Mountains (which includes a portion of Eastern Oregon, east of the centerline of Highway 395 and Highway 78 north of Burns Junction and that portion of Oregon east of the centerline of Highway 95 south of Burns Junction). Any wolves found west of this line in Oregon belong to the conterminous USA population [see 73 FR 10514]. Gray wolves in Oregon are State-listed as endangered, regardless of location.
