1.0 Introduction ~owderhorn Coal Company needs to have additional refuse disposal areas, a new portal, and a fan installation site to support the existing Roadside Mine, located near Palisade, Colorado in Mesa County. Figure 1 illustrates the location of the four sites, which total about 137 acres in area. However, only a portion of each of these areas would be disturbed A survey for federally listed plants and species of concern to the U.S. Bureau of Land Management (USBLM) was conducted for submission to the Colorado Division of Minerals and Geology. 2.0 Methods The U.S. Fish and Wildlife Service (USFWS), the USBLM, and the Colorado Natural Heritage Program (CNHP), were contacted to determine the species of potential concern. The USFWS (Rose 1996) identified Uinta Basin hookless cattus (Sclerocactus glaucus), a federally threatened plant, and Debeque phacelia (Phacelia submutica), a federal candidate plant, as the only species of concern. The USBLM (Smith 7996) provided a list of Special Status Plants in the Grand )unction Resource Area (Appendix B). The CNHP provided a list of rare, threatened and endangered species and significant natural communities for Mesa County. Table 1 provides a list of USBLM Special Status Plants potentially present in Mesa County and lists the habitat of these plants. Most, if not all, of these plants occur in habitats not present in the project area, and therefore, are not likely to be present. However, the field ecologist looked for these plants during the field survey. `Prior to the field survey, the ecological literature and taxonomic descriptions of Uinta Basin hookless cactus and Debeque phacelia was reviewed, and herbarium specimens of both plants were studied at the University of Colorado Herbarium in Boulder, Colorado. Additionally, the taxonomic descriptions on the special status plants was also reviewed. On May 7 prior to beginning the survey, Daryl E. Mergen, the ecologist conducting the field survey, visited a known site of Uinta Basin hookless callus southwest of Debeque, Colorado to determine if this small plant was flowering. At this known site, Uinta Basin hookless cacti was Flowering (Photo 1). On May 7 and 8, 1996, parallel transects, about 30 feet, were walked through all four survey sites to look for the occurrence of Uinta Basin hookless cactus, Debeque phacelia, and any USBLM Special Status Plant. Because of the steep, rocky topography at the Cameo Refuse Disposal Areas Number 2 and 3, transects were generally walked up and down small ridges and down steep side slopes. Extra time was spent on areas of barren clay soil, potential as habitat for Debeque phacelia.
