forbs, introduced perennial forbs, native perennial graminoids (includes grasses and grass -like <br />plants), introduced perennial graminoids, native shrubs, native trees, bryophytes, succulents, and <br />fungi. <br />Plant Species Frequency and Density Measurements <br />During the course of cover sampling, all plant species occurring within one meter of either side of <br />the cover sample transect were noted as present. Frequency for each plant species observed <br />during sampling was calculated by dividing the number of sample transects in which the species <br />was observed by the total number of samples (see cover sample distribution by area above). As <br />such, this value is probably more correctly known as constancy. <br />The total number of species within each lifeform observed in each 100 square meter sample <br />provides a measure of "species density ", indicating the relative species richness of different <br />areas. This measure provides 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 Wittmann (2001); 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 revised names used here can be made by referring to Appendix B of <br />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 potentially affected vegetation type and for the <br />three reference areas. These lists are tubulated in Appendix B, "Species Presence for All Areas." <br />Note that all big sagebrush plants encountered were referred to as Seriphidium tridentatum. <br />Plants referred to here as Poa secunda are the plants formerly known as big bluegrass (Poa <br />ampla) a species commonly included in reclamation seed mixes. The taxonomic treatment of <br />Weber and Wittmann (1996) places Poa ampla (as well as Poa sandbergii) with Poa secunda. <br />Despite this merger, the distinctness of Poa ampla is worth noting. Mountain bromegrass <br />encountered during sampling is referred to as Ceratochloa polyantha in recognition of its <br />perennial habit compared to the C. carinatus taxon described in Weber and Wittmann (2001) <br />which is an annual. <br />Photographic Record <br />Within each reclamation and reference area, representative color photographs were taken to <br />document the appearance of the vegetation in 2011 (Appendix E). Within each photograph, a <br />placard identifies the particular area being illustrated. <br />3 <br />
