• The total number of species (within each fifeform) observed in each 100 square meter sample <br />provides a measure of "species density", indicating the relative species richness of different <br />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 to <br />the substantially revised scientific nomenclature for the flora of Western Colorado, as set fourth <br />by Weber and Wittman (1996), may be determined by reference to Weber and Wittman (1992) or <br />by reference to Appendix 2 of this report (Table 16). <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, Table 16, Species Present in All Areas, which <br />includes current nomenclature and cross references to older nomenclature. It should be noted <br />that all big sagebrush plants 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 2001 (Appendix 5). Within each photograph, a <br />placard identifies the particular area being illustrated. <br />Statistical Methods <br />Statistical Design <br />Cover and herbaceous production data were collected in all areas using asingle-stage sample <br />design. Single-stage sampling of woody plant density was conducted in all reclamation areas <br />with the exception of Wadge Pasture. In Wadge Pasture, woody plant density samples were <br />collected using atwo-stage 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 by hand on maps of 1:4,800 scale. <br />Sample locations were selected from the numbered grid cells. The SCC-assigned numbers of <br />
