Plant Species Freo~iency and Den~(y Measurements <br />During the course of cover sampling, all plant species occurring within one meter on gi~1L@.[ side <br />of the cover sample transect were noted as present within each sample. 1=requency for each <br />plant species observed during sampling was calculated by dividing the number of sample <br />transects in which the species was observed by the total number of samples (see cover saample <br />distribution by area above). As such, this value is probably more correctly known as <br />"constancy". Relative vegetation cover was calculated by dividing the absolute cover of each <br />species by the total vegetation cover with the result expressed as a peres~nt. <br />The total number of species (within each lifeform) observed in each sample provide a measure <br />of "species density", indicating relative species richness of different areas. These measures <br />reflect progress toward return of diverse species composition in the reclaimed areas from a <br />different perspective than is available from examination of cover data alone. <br />Plant Series Listing <br />• <br />During the course of the field work, a list of all encountered plant specif:s (quantitative plus <br />incidental observations) was compiled for each reclamation area and the two reference areas. . <br />Scientific names used follow Weber and Wittman (1992); common names. cited may be found in <br />Beetle (1970), Nickerson et al. (1976), or SCS (1979). Cross reference to the substantially <br />revised scientific nomenclature for the flora of Western Colorado, as set forth by Weber <br />(1987), may be determined by reference to Weber and Wittman (1992). <br />Reference Area Sampling <br />The Mountain Brush and Sagebrush reference areas were sampled to provide data for <br />comparison with reclaimed area data. Cover and production data were collected as they were in <br />the reclaimed areas. <br />Photooranhic Record <br />Within each reclamation and reference area, representative color photographs were taken to <br />document the appearance of the vegetation in 1994. Within each photo, a placard identifies the <br />particular reclamation area being illustrated. Photo locations are shown on the sample location <br />map (Map 1). <br />6 • <br />
