FEDERAL STATUS

LE = Listed endangered
LT = Listed threatened
LELT = Listed endangered in part of range, threatened in part of range
C = Candidate for federal listing, information indicates that listing is justified.
PE = Proposed endangered.
PT = Proposed threatened.

STATE STATUS

SE = State Endangered.
ST = State Threatened.

An endangered species is a species in danger of extinction throughout all or a significant portion of its range (applied rangewide for federal status and statewide for state status)

A threatened species is a species likely to become endangered in the foreseeable future.

Global/State Rank Definition (applied rangewide for global rank and statewide for state rank)

G1, S1 = Critically imperiled because of extreme rarity (5 or fewer occurrences or very few remaining individuals or acres) or because of some factor(s) making it especially vulnerable to extinction.

G2, S2 =  Imperiled because of rarity (6 to 20 occurrences or few remaining individuals or acres) or because of some factor(s) making it very vulnerable to extinction throughout its range.

G3, S3 =  Either very rare and local throughout its range, or found locally (even abundantly at some of its locations)in a restricted range,or vulnerable to extinction throughout its range because of other factors; in the range of 21 of 100 occurrences.

G4, S4 =  Apparently secure, though it may be quite rare in parts of its range, especially at the periphery with cause for long term concern.

G5, S5 =  Demonstrably secure, though it may be quite rare in parts of its range, especially at the periphery.

GU, SU =  Possibly in peril, but status uncertain, more information needed.

GH, SH = Historically known to occur, could be rediscovered.

GX, SX =  Believed extinct, historical records only.

G?, S? = Not yet ranked

_?, _? = Inexact rank

_T = Rank of subspecies or variety

_Q =  Taxonomic status is questionable, rank may change with taxonomy

SZ =  No definable occurrences for conservation purposes, usually assigned to migrants

SP =  Potential exists for occurrence in the state, but no occurrences

SR = Element reported for the state but no persuasive documentation

SA = Accidental or casual
