Two Dot staff completed Special Status Plant Species Surveys for existing populations of four Threatened and Endangered plant species as well as 14 at-risk species within 3,200 acres in Rio Blanco County, Colorado. A total of 497 miles were walked by 10 biologists in 9 field days. Field data contributed to the evaluation of direct, indirect, and cumulative effects associated with the project. All data were provided to the BLM Field Office to facilitate analyses for biological assessments needed for formal and informal consultation with the United States Fish and Wildlife Service (FWS) and to provide the Colorado Native Heritage Program with updated survey information for BLM lands in Rio Blanco County.
