Short Definitions of Codes Used in Above Table

Committee (Scientific Council on Freshwater and Terrestrial Crustaceans; Clamp 1999) Rank: E = endangered; T = threatened; SC = special concern; U = undetermined status; C = common; O = occasional; I = infrequent; * = species not described at time

State (NC Wildlife Resources Commission) Status: E = endangered; T = threatened; SC = special concern; WL = watch list; (P) = proposed listing by above Committee, effective 1 July 2002.  The only officially recognized state statuses are E, T, and SC (WL is provided as a precautionary measure, to allow resource users to proceed with caution).

NCSM (NC State Museum of Natural Sciences) Rank: E = endangered; T = threatened; V1 = vulnerable, category 1 (enough info to list); V2 = vulnerable, category 2 (should probably list, but not enough info to confirm); V3 = vulnerable, category 3 ("watch list"; more widespread than previously thought but may be re-elevated with more info)

USFWS (US Fish & Wildlife Service): E = endangered; T = threatened; Proposed = officially proposed for listing; Status Review = being considered for listing (3 categories): Category 1 = similar to V1 above; Category 2 = similar to V2 above; Category 3 = no longer being considered for listing due to (a) believed to be extinct, (b) not falling into definition of "species", (c) similar to V3 above.

Natural Heritage Program Ranks*:

    Global Rank: assigned by NatureServe (international association of heritage programs):
    Bracketed (e.g., [G3G4]) are those suggested by the NC Scientific Council, and are not The Nature Conservancy's assigned ranks.

        G1 = Critically imperiled globally because of extreme rarity or because of some factor(s) making it especially vulnerable to extinction.
        G2 = Imperiled globally because of rarity or because of some factor(s) making it especially vulnerable to extinction.
        G3 = Either very rare and local throughout its range, or found locally (even abundantly at some of its locations)  in a restricted range
                 (e.g., a single physiographic region) or becuase of other factors making it vulnerable to extinction throughout its range.
        G4 = Apparently secure globally, though it may be quite rare in parts of its range, especially at the periphery.
        G5 = Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.
        GU = Possibly in peril range-wide, but status uncertain; more information is needed.
        G? = Unranked, or status uncertain.

    State Rank:

        S1 = Critically imperiled in state because of extreme rarity or because of some factor(s) making it especially vulnerable to extirpation from state.
        S2 = Imperiled in state because of rarity or because of some factor(s) making it very vulnerable to extirpation from state.
        S3 = Rare or uncommon in state.
        S4 = Apparently secure in state, with many occurrences
        S5 = Demonstrably secure in state and essentially ineradicable under present conditions.
        SA = Accidental or casual; one to several records for state, but the state is outside the normal range of the species.
        SU = Possibly in peril in state but status uncertain; need more information.
        S? = Unranked, or status uncertain.

    State Status: E = Endangered; T = Threatened; SC = Special Concern; P = Proposed (E,T, or SC); SR = Significantly Rare; W = Watch list, with categories below

        W1 = Watch List, category 1:  species known to be declining in the state; may need listing in upcoming years.
        W2 = Watch List, category 2:  species rare to uncommon, but probably not in trouble.
        W3 = Watch List, category 3:  species that is poorly known; perhaps needs listing in upcoming years.
        W4 = Watch List, category 4:  species reported from the state without adequate documentation.
        W5 = Watch List, category 5:  species with increasing amount of threats to its habitat, whether populations are known to be declining or not.

    Federal Status: E = Endangered; T = Threatened; C = Candidate (with categories similar to others); FSC = proposed for federal special concern
