Addendum to Section II.F.4.a(2) Threatened and Endangered Species
Discussions within this section appear to originate from a survey which included several corridors for
transporting coal to the Bonanza Station in Utah. The species listed were located in the extreme
western side of Colorado on or in the vicinity of Raven Ridge, a considerable distance from the Deserado
Mine. Since the original survey, species statuses have been changed as outlined below. In addition,
Astragalus detritalis, debris milkvetch, was located at one location on the extreme eastern edge of the
Deserado Mine's permit boundary after the original survey was complete.

Nature Conservancy Natural Heritage Ranks — Global rank.
G2 Imperiled globally because of rarity (6 to 20 occurrences) or because of other factors
demonstrably making it very vulnerable to extinction throughout its range.
G3 Vulnerable throughout its range or found locally in a restricted range (21 to 100 occurrences).
G4 Apparently secure globally, though it might be quite rare in parts of its range, especially at the
periphery.
Colorado State Ranks - based on the status of a species in Colorado
S1 Critically imperiled in State because of extreme rarity (5 or fewer occurrences, or very few
remaining individuals, or because of some factor of its biology making it especially vulnerable to
extirpation from the state.
S2 Imperiled in State because of rarity (6 to 20 occurrences) or because of other factors
demonstrably making it very vulnerable to extirpation from the state.
