**[Classification Definitions]{.underline}**

**E -- Endangered --** A species in danger of extinction throughout all
or a significant portion of its range.

**T -- Threatened** -- A species likely to become endangered within the
foreseeable future throughout all or a significant portion of its range.

**P -- Proposed** -- A species proposed for federal listing as
endangered or threatened.

**C -- Candidate** -- Those species for which sufficient information on
biological status and threats exist to propose to list them as
endangered or threatened. We encourage their consideration in
environmental planning and partnerships; however, none of the
substantive or procedural provisions of the Endangered Species Act apply
to candidate species.

**Cw -- Candidate, Warranted but precluded** -- The petitioned listing
action is warranted but that (a) the immediate proposal of a regulation
and final promulgation of regulation implementing the petitioned action
is precluded by pending higher priority proposals, and (b) expeditious
progress is being made to add qualified species to the lists of
endangered or threatened species.

**SA -- Similarity of appearance** -- A species that is listed as
endangered or threatened because it closely resembles another endangered
or threatened species. This species is not subject to Endangered Species
Act, Section 7 consultation.

**PDL -- Proposed for delisting** -- Any species for which a proposed
rule to delist the species has been published in the Federal Register.

**CH -- Critical habitat designated** -- The specific areas within the
geographic area occupied by a species, at the time it is listed, on
which are found those physical or biological features essential to
conserve the species and that may require special management
considerations or protection; and specific areas outside the geographic
area occupied by the species at the time it is listed upon determination
that such areas are essential to conserve the species.

**R/D -- Recovered/Delisted --** The factors that initially led to a
species listing are remedied and protection under the Endangered Species
Act is no longer needed. Only when adequate legal mechanisms independent
of the Act are implemented to manage a listed species whose populations
have recovered can the species be truly said to no longer require
Endangered Species Act protection and thus be considered for delisting.

**M -- Monitored** --The 1988 amendments to the Act recognized this
potential conflict involving recovered/delisted species and their
removal from the protective oversight of the Act. Section 4 of the Act
was amended by adding a requirement that recovered species be monitored
for at least 5 years after delisting.

**X -- Extinct** -- A species no longer in existence.
