Species for which a Federal agency, bureau, or service has sufficient information on the species' status and threats to support proposing the species for listing as endangered or threatened under the Endangered Species Act (ESA) but for which issuance of a proposed rule is currently precluded by higher priority listing actions.
(3) species not protected under the Endangered Species Act but under consideration by the US Fish and Wildlife Service for inclusion on the list of federally threatened or endangered species.
a species for which we have on file sufficient information to propose it for protection under the Act
a species under review for listing
any species being considered by the Secretary (of Commerce or Interior) for listing under the ESA as an endangered or a threatened species, but not yet the subject of a proposed rule (see 50 CFR 424.02). Species can qualify as both "species of concern" and "candidate species." "Candidate species" refers to - species that are the subject of a petition to list and for which NMFS has determined that listing may be warranted, pursuant to ESA section 4(b)(3)(A), and species for which NMFS has determined, following a status review, that listing is warranted (whether or not they are the subject of a petition).
plants and animals for which enough scientific information exists to warrant a proposal for listing as endangered or threatened The candidate designation can be thought of as a population that is teetering on the edge of a critical illness and is being carefully watched; the population is closely monitored to determine if they need to be included on the state or federal threatened or endangered species lists. These populations are not stable, and, in some cases the viability of that species is in question
Legal listing of a species for which there is sufficient data on status and threats to propose them as endangered or threatened under the Endangered Species Act, but for which development of a listing regulation is precluded by other higher priority listing activities
those species for which the Service has on file sufficient information on biological vulnerability and threats to propose them for listing.
A species for which concerns remain regarding their status, but for which more information is needed before they can be proposed for listing under the ESA as threatened or endangered.
Plants and animals that have been studied and the Service has concluded that they should be proposed for addition to the Federal endangered and threatened species list. These species have formerly been referred to as category 1 candidate species. From the February 28, 1996 Federal Register, page 7597: "those species for which the Service has on file sufficient information on biological vulnerability and threat(s) to support issuance of a proposed rule to list but issuance of the proposed rule is precluded."
any species being considered by the Secretary (of Commerce or Interior) for listing under the ESA as an endangered or a threatened species, but not yet the subject of a proposed rule (see 50 CFR 424.02). NMFS' candidate species also qualify as species of concern. "Candidate species" specifically refers to - species that are the subject of a petition to list and for which NMFS has determined that listing may be warranted, pursuant to ESA section 4(b)(3)(A), and species that are not the subject of a petition but for which NMFS has announced the initiation of a status review in the Federal Register.
