The Fish and Wildlife Service recently published an updated list of plant and animal species native to the United States that are candidates for listing as threatened or endangered species under the Endangered Species Act.  The list, referred to as a Candidate Notice of Review or CNOR, is published periodically by the Service.  A press release announcing the release of the CNOR is available here.  Each species on the list is assigned a listing priority number (or LPN) based on its status and threats.  The CNOR includes five new candidates, changes the LPN for four existing candidates, and removes one species from candidate status.  The CNOR contains a total of 251 species.
