areas. These measures provide a means of examining progress toward the return of diverse <br />• species composition in the reclaimed areas. <br />Plant Species Listing <br />Scientific names used follow Weber and Wittman (1996); common names cited are found in <br />Beetle (1970), Nickerson et al.. (1976), or Soil Conservation Service (1979). Cross reference <br />between older names and the revised scientific nomenclature for the flora of Western Colorado <br />used here can be made by reference to Appendix 2 of this report. <br />During the course of the fieldwork, a list of all plant species encountered (quantitative plus <br />incidental observations) was compiled for each reclamation area and the three reference areas. <br />These lists are summarized in Appendix 2, Species Present in All Areas, which includes current <br />nomenclature and cross references to older nomenclature. Note that all big sagebrush plants <br />encountered were referred to as Seriphidium tridentatum. <br />Photographic Record <br />Within each reclamation and reference area, representative color photographs were taken to <br />document the appearance of the vegetation in 2002 (Appendix 4). Within each photograph, a <br />placard identifies the particular area and sample. <br />• Statisfica/ Methods <br />Statistical Design <br />Cover and herbaceous production data were collected in all areas using asingle-stage sample <br />design. Single-stage random sampling of woody plant density was conducted in all reclamation <br />areas with the exception of Wadge Pasture. In Wadge Pasture, woody plant density samples <br />were collected using atwo-stage random design. <br />SINGLE-STAGE SAMPLING <br />Each reclamation and reference unit identified in the SCC Scope of Work was gridded and <br />numbered. Grid cell size was 100 feet X 100 feet in reclaimed areas, and 50 feet X 50 feet in <br />reference areas. These grid cells were placed contiguously on maps of 1:4800 scale. Sample <br />locations were selected from the numbered grid cells. The SCC-assigned numbers of samples <br />for a given parameter in a given area reflected previously experienced sample variability or the <br />level of precision required in a given area. Random numbers generated by computer were used <br />to select grid cells, in the middle of which a sample point was placed, and recorded on the field <br />. maps. These sample points were located as accurately as possible in the field using aerial and <br />topographic maps and pacing from known locations. Cover and woody plant density transects <br />
