Key to codes used in Natural Heritage Database species list:

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. 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, may 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

Bird species may have two state ranks, one for breeding (S#B) and one for nonbreeding seasons (S#N). Example: Ferruginous Hawk (S3B,SZN) indicates an S3 rank in breeding season and SZ in nonbreeding season.
