During the course of the fieldwork, a list of all encountered plant species <br />{quantitative plus incidental observations) was compiled for each reclamation <br />area and the three reference areas. These lists are summarized in Appendix 2, <br />Table 17, Species Present -Reclaimed and Reference Areas, which includes <br />current nomenclature and cross references to older nomenclature. It should be <br />noted that all big sagebrush encountered are referred to as Seriphidium <br />tridentatum. <br />Photographic Record <br />Wthin each reclamation and reference area, representative color photographs <br />were taken to document the appearance of the vegetation in 2005 (Appendix 4). <br />Within each photograph, a placard identifies the particular area being illustrated. <br />Statistical Methods <br />STATISTICAL DESIGN <br />Cover and herbaceous production data were collected in all areas. Woody plant <br />density samples were collected in the 1998 and 2003 Reclaimed Areas but were <br />not collected in any of the reference areas, Sampling proceeded using a single <br />stage statistical design. <br />Sample locations in reclaimed areas were randomly plotted by use of an internal <br />script routine within ArcView software. Minimum spacing between sample points <br />was 170 feet (one 50 m transect length). The SCC-assigned number of samples <br />for a given parameter in a given area reflected previously experienced sample <br />variability or the level of precision required for that area. <br />In the extended reference areas, each reference unit was gridded and numbered. <br />Grid cell size was 200 feet X 200 feet. These grid cells were placed contiguously <br />by hand on maps of 1:4,800 scale. Sample locations were selected as the center <br />points of grid cells selected using random numbers generated by computer. <br />Sample points were located in the field using topographic maps. Cover and <br />woody plant density transects were located and oriented using a blind throw of a <br />
