Lifeforms Used in Data Presentation <br />As a tool to enhance understanding of the collected data, the contents of all data and summary <br />tables are organized by lifeform. Lifeform categories used here reflect growth habit and <br />provenance (place of origin). Lifeform categories used include the following: native annual and <br />biennial forbs, introduced annual and biennial forbs, introduced annual grasses, native perennial <br />forbs, introduced perennial forbs, native perennial cool season graminoids (includes grasses and <br />grass -like plants), introduced perennial cool season graminoids, native shrubs, native trees, <br />bryophytes, lichens, and succulents. <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 Flora of North America (1993 — 2013); common names cited are <br />found in Beetle (1970), Nickerson et al. (1976), or Soil Conservation Service (1979). Cross - <br />reference between older names and revised names used here can be made by referring to <br />Appendix C 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 potentially affected vegetation type and for the <br />three reference areas. These lists are tabulated in Appendix C, "Species Presence for All Areas." <br />Note that all big sagebrush plants encountered were referred to as Artemisia tridentata, formerly <br />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 2013 (Appendix E). Within each photograph, a <br />placard identifies the particular area being illustrated. <br />3 <br />
