USDA UAS <br /> sensitive species — Federally listed threatened or endangered species or designated <br /> critical habitat, species proposed for Federal listing or proposed critical habitat, or Forest <br /> Service sensitive species. There are 10 Forest Service Sensitive species (Fringed myotis, <br /> Hoary bat, Townsend's bit-eared bat, Peregrine falcon, Bald eagle, Flammulated owl, <br /> Northern goshawk, Olive-sided flycatcher, Northern leopard frog, and Boreal toad) and 1 <br /> Federally — threatened species (Mexican spotted owl) that have the potential to occur <br /> within the Analysis area which is defined as one mile from the footprint of the proposed <br /> action. No observations of any of these species have been recorded within one mile of <br /> the project area. There is no critical or proposed critical habitat for any species in the <br /> project area. <br /> The Forest Service sensitive species Fringed myotis, Hoary bat, Townsend's bit-eared <br /> bat, Peregrine falcon, Bald eagle, Flammulated owl, Northern goshawk, Olive-sided <br /> flycatcher, Northern leopard frog, and Boreal toad were analyzed because 0.5 acre of <br /> habitat would be directly impacted. This is a minute amount of habitat and it is unlikely <br /> these species utilize this piece of land during the summer because of the ongoing <br /> activities. There is suitable habitat for all these species adjacent to the proposed action <br /> where they likely prefer to forage and rest. No habitat would be directly impacted. There <br /> are already noise disturbances in the area due to other mining operations in Crystal <br /> Creek, and without an acoustical study it is unknown as to how much disturbance the <br /> additional noise would cause. Once the project is completed, wildlife use of the area <br /> would likely return to pre-implementation levels. Because this proposed project will take <br /> place during the daylight hours of the summer months, it is determined that the project <br /> may adversely impact individuals but will not likely result in a loss of viability in the <br /> planning area for all sensitive addressed in this analysis. <br /> A separate Biological Assessment and Biological Evaluation were completed for <br /> botanical and wildlife species. They are included in the project record. <br /> b. Flood plains,wetlands, or municipal watersheds — The project will not occur within or <br /> affect floodplains, wetlands, or municipal watersheds. (Project file record: Ulrich - <br /> Rovedo MPO Map, 2019). <br /> c. Congressionally designated areas such as wilderness, wilderness study areas, or <br /> national recreation areas — The project will not occur within or affect any <br /> congressionally designated areas (Project file record: Location of Ulrich - Rovedo <br /> MPO Map, 2019). <br /> d. Inventoried roadless areas or potential wilderness areas — The project will not occur <br /> within or affect inventoried roadless areas (Project file record: Ulrich - Rovedo MPO <br /> Map, 2019). <br /> e. Research natural areas — The project will not occur within or affect research natural <br /> areas (Project file record: Location of Ulrich -Rovedo MPO Map, 2019). <br /> f. American Indians and Alaska Native religious or cultural sites —There are no known <br /> Native American or Alaska Native religious or cultural sites within the project area <br /> (Project file record: Cultural Resources Investigation #R2019021210012) for the <br /> Ulrich - Rovedo MPO, Colorado). <br /> —Decision Memo— <br /> Page 3 of 9 <br />
