Federal Status Definitions:
E: "Endangered" - A species in danger of extinction within the foreseeable future throughout all or a significant portion of its range.
T.• "Threatened" - A species likely to become endangered within the foreseeable future throughout all or a significant portion of its range.
PT, PE: "Proposed Threatened, Proposed Endangered" - May soon be uplisted to Threatened or Endangered.
C: "Candidate" - May soon become Proposed as Threatened or Endangered.
State Ranking Definitions:
Sl: "Critically Imperiled" - Critically imperiled because of extreme rarity or because of some factor(s) making it especially vulnerable to extirpation or extinction. Typically 5 or fewer occurrences or less than 1,000 remaining
individuals.
S2: "Imperiled" - Imperiled because of rarity or because of some factor(s) making it very vulnerable to extirpation or extinction. Typically 6 to 20 occurrences or between 1,000 and 3,000 remaining individuals.
S3: "Vulnerable" - Vulnerable either because rare and uncommon, or found only in a restricted range (even if abundant at some locations), or because of other factors making it vulnerable to extirpation or extinction. Typically 21 to
100 occurrences or between 3,000 and 10,000 remaining individuals.
Likelih000d Definitions for Plants (created by Barr Engineering for this study):
Some Likelihood: The project site is within the species' range and onsite habitat, substrate, and elevation is suitable for the species. The species is thought to be more common and/or occurs in a wider range of habitats.
Unlikely: Very little possibility that a population previously undocumented in Gunnison County may occur in the project site. Known populations occur in nearby Counties and the habitat/substrate and elevation are substantially
appropriate for the species. However, due to species rarity, it remains very unlikely that the species would occur within the project site.
Very Unlikely: Either known species populations are not within close regional proximity (i.e. adjacent or nearby Counties), or the habitat/substrate and/or elevation is largely inappropriate for the species.
No likelihood: The appropriate habitat and/or substrate and elevation does not exist on the project site and known occurrences of the species are not within or adjacent to Gunnison County. It is unreasonable to assume any likelihood
for species occurrence onsite.
