1 Introduced species
Federal Status
E = Endangered
T = Threatened
C = Candidate for listing
* = Formerly listed as C2 (candidate for listing). This category was dropped in 1996.
E = Endangered
NOTE: All other classifications were dropped in 1998.
State Rank
Numerical rank of relative indangerment for the species within the state based on the number of known occurrences.
S1 = Critically imperiled in the state because of extreme rarity or because of some factor(s) making it especiallly vulnerable to extirpation from the state.
S2 = Imperiled in the state because of rarity or because some factor(s) making it very vulnerable to extirpation from the state.
S3 = Rare or uncommon in the state.
S4 = Widespread, abundant, and apparently secure in the state, but of long-term concern.
S5 = Demonstrably widespread, abundant, and secure in the state, and essentially eradicable under present conditions.
S#S# =Indicates range of uncertainty of the exact numerical ranking for the species.
? = denotes ranking which is uncertain.
Global Rank
Numerical ranking of relative endangerment for the species worldwide. The categories are similar to those listed above for State Rank.
