Pinnacle NAP: Flora

12 rare plants

Global Conservation Ranks
The Nature Conservancy, NatureServe, and all state Natural Heritage programs use the following system for ranking the range-wide conservation status of vegetation types at the association level. Intermediate ranks (e.g., G3G4) may also be used. A question mark added to a rank expresses an uncertainty about the rank in the range of one either way on the 1-5 scale. For example a G2? rank indicates that the rank is thought to be a G2, but could be a G1 or a G3. A Q added to a rank denotes questionable taxonomy. It modifies the degree of imperilment and is only used in cases where the type would have a less imperiled rank if it were not recognized as a valid type (i.e., if it were combined with a more common type).
G1 critically imperiled throughout range.
G2 imperiled throughout range.
G3 rare or uncommon.
G4 widespread, abundant, and apparently secure, but with cause for long-term concern.
G5 demonstrably widespread, abundant, and secure.
GNR unranked; conservation status has not yet been assessed.
GNA not applicable because the community is not a suitable conservation target; usually assigned to ruderal, modified / disturbed, or managed vegetation.
State Conservation Ranks
VANHP ecologists employ a similar system for ranking the state-wide status of community types. Intermediate ranks (e.g., S3S4) may also be used.
S1 extremely rare, generally with = five occurrences state-wide, and/or covering < 50 ha (125 ac) in aggregate; or covering a larger aggregate area but highly threatened with destruction or modification.
S2 very rare, generally with six to 20 occurrences state-wide, and/or covering < 250 ha (600 ac) in aggregate; or covering a larger aggregate area but threatened with destruction or modification.
S3 rare to uncommon, generally with 21 to 100 occurrences state-wide; or with a larger number of occurrences subject to relatively high levels of threat; may be of relatively frequent occurrence in specific localities or geographic parts of the state.
S4 common, at least in certain regions of the state, and apparently secure, but with cause for long-term concern.
S5 very common and demonstrably secure.
SNR unranked; conservation status has not yet been assessed.
SNA not applicable because the community is not a suitable conservation target; usually assigned to ruderal, modified / disturbed, or managed vegetation.
