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 Ranking

Process:

Global ranks are periodically reviewed by species experts and shared throughout the NatureServe Network. State or provincial ranking is the responsibility of individual heritage programs. 

The goal of state, provincial and global species ranking is to assess extinction risk using standard methods. NatureServe and network program staff collect and evaluate data with established tools and methods to assign ranks that are as accurate and consistent as possible given the data available on a species. Major categories assessed during species ranking are rarity, threats and trends. 

South Dakota Heritage Program staff began a comprehensive review of state ranks in 2016. The process should be completed during 2022, with a goal to reassess species ranks at least every five years.

Ranks and definitions:

These are 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 Unrankable due to lack of information or conflicting information about status or trends.

GH SH Historically known, may be rediscovered.

GX SX Believed extinct, historical records only.

GNR SNR Not yet ranked

GNA SNA Not applicable – A conservation rank is not applicable because the species is not a suitable target for conservation activities.

Rank qualifiers:

_? _? Inexact rank
_C Captive or cultivated only
_Q Taxonomic status is questionable, rank may change with taxonomy

Infraspecific taxon rank:

_T Rank of subspecies or variety
