Addendum to Section II.F.4.a(2) Threatened and Endangered Species <br />• Discussions within this section appear to originate from a survey which included several corridors for <br />transporting coal to the Bonanza Station in Utah. The species listed were located in the extreme <br />western side of Colorado on or in the vicinity of Raven Ridge, a considerable distance from the Deserado <br />Mine. Since the original survey, species statuses have been changed as outlined below. In addition, <br />Astragalus detritalis, debris milkvetch, was located at one location on the extreme eastern edge of the <br />Deserado Mine's permit boundary after the original survey was complete. <br />Scientific Name Common Name Listing Status ** <br />Astragalus duchesne Duchesne milkvetch G3, S1S2, BLM-S <br />Eriogonum ephedroides ephedra buckwheat G3, S1, BLM-S <br />Mirabilis alipes Uintah hermidium G4, S1 <br />Parthenium ligulatum <br />a.k.a.
