Codes Used In Natural Heritage Reports
FEDERAL STATUS CODES
The following categories and definitions of endangered and threatened plants and animals have been modified
from the U.S. Fish and Wildlife Service (F.R. Vol. 50 No. 188; Vol. 61, No. 40; F.R. 50 CFR 17).
LT:
Taxa formally listed as threatened.
STATE STATUS CODES:
E: Indicates taxa listed as endangered on New Jersey's official Endangered Plant Species List N.J.A.C.
7:5C-1.1.).
GLOBAL ELEMENT RANKS:
G1: Critically imperiled globally 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: Imperiled globally 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: 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 physiographic region in the East) or because
of other factors making it vulnerable to extinction throughout its range; with the number of
occurrences in the range of 21 to 100.
G4: Apparently secure globally; although may be quite rare in parts of its range, especially at the
periphery.
G5: Demonstrably secure globally; although it may be quite rare in parts of its range, especially at the
periphery.
G?: Species has not yet been ranked.
Q: Taxon is of questionable, or uncertain taxonomical standing.
T: Infraspecific taxon is ranked differently than the full species.
STATE ELEMENT RANKS (Specific to New Jersey):
S1: Critically imperiled in New Jersey because of extreme rarity (5 or fewer occurrences or very
few remaining individuals or access). Species so ranked are often restricted to an extremely
small (3%) geographical area of the state. Also included are species which were formerly more
abundant, but because of habitat destruct or some other critical factor of its biology, they have
been demonstrably reduced in abundance. In essence, these are species for which, even with
intensive searching, sizable addition occurrences are unlikely to be discovered.
S2: Imperiled because of rarity (6 to 20 occurrences), due primarily to habitat destruction.
