Rifle Grave; P11 ? January 2023 <br /> parcel would have no effect for the listed Colorado River endangered fish species and their <br /> Critical Habitats. <br /> Monarch butterfly—Candidate. Candidate species are not afforded full protection under <br /> the ESA; however, the USFWS encourages their consideration in environmental planning, <br /> and the USFWS regulatory guidance indicates that Candidate species should be treated <br /> similarly to Proposed Species with regard to inter-agency consultation requirements. <br /> Informal consultation is requested when a provisional "is likely to jeopardize" determination <br /> is reached for a Candidate species (USFWS Sec7 Consultation Handbook, 1998). <br /> Monarch butterfly adults feed (gather nectar) from a variety of flowering plant species. <br /> However, the monarch butterfly only lays eggs and larvae only feed on milkweeds <br /> (Asclepias spp.). The western population overwinters in various coastal sites in central and <br /> southern California, and central populations overwinter in Mexico. Monarchs have multiple <br /> generations during their migrations; the second, third and fourth generations return to their <br /> northern locations in the United States and Canada in the spring. <br /> The project area contains migratory and overwintering habitat for the monarch butterfly. <br /> Showy milkweed (Asclepias speciosa) is an abundant component of the vegetation in the <br /> transitional zones along the boundaries of the wetland areas. Adult butterflies and several <br /> monarch caterpillars were observed feeding on milkweeds at the western edge of the <br /> property. Western Colorado is not part of a major monarch migration corridor, but the site is <br /> being used by migrating adults and as a potential overwintering site for the dispersed <br /> population in the area. <br /> Proposed development would occur primarily outside the mesic/wetland meadows where <br /> the majority of milkweed is located, therefore direct impacts to host plants and habitats <br /> would be largely avoided. The project would result in the complete loss of vegetation from <br /> approximately 19.00 acres of the property, which would result in potential direct impacts to <br /> chrysalis and caterpillars and reduce the foraging vegetation available to adult butterflies. <br /> This may result in minor, localized impacts to migrating monarch butterflies, and may reduce <br /> the attractiveness of the site as an egg-laying site. <br /> Development of the parcel is not likely to jeopardize this Candidate species, as the project <br /> may affect individuals but is not expected to alter the species' overall range and life history <br /> patterns. USFWS consultation is not required by ESA for Candidate species where an <br /> action is not likely to jeopardize the species' existence. Garfield County, however, requested <br /> documentation of communication with the USFWS, included in Attachment C. <br /> Ute Ladies'-Tresses -Threatened. The project area occurs outside the known range of the <br /> Ute ladies'-tresses orchid, and is a significant distance from the nearest known populations <br /> in the Roaring Fork Valley. The parcel does contain wet meadow conditions that are <br /> potentially suitable habitat for the species, although similar habitats in the Colorado River <br /> valley have been searched repeatedly and no orchids have ever been located. The potential <br /> habitats on the parcel have been incidentally evaluated by a trained and experienced orchid <br /> surveyor in the course of wetland assessments, and no orchids have been located. <br /> However, no systematic survey meeting USFWS standards has been undertaken on the <br /> parcel at this time. Activities on the parcel are not expected to directly impact effective <br /> habitats since the wetland areas that constitute habitat for the species will be avoided, and <br /> the project is not expected to change the existing hydrology that supports these wetlands <br /> due to the proposed wet mining development process. Given the location outside of the <br /> known range, and the avoidance of impacts to potentially suitable habitat, activities on the <br /> parcel would have no effect on the Ute ladies'-tresses orchid. <br /> 19 <br />
