Woody Plant Density Sampling <br />Woody plant density sampling was undertaken in all reclaimed areas sampled but not in the reference <br />areas. Samples were collected along 50 m transects. All shrubs and subshrubs with root crowns located <br />within the boundaries of 2 X 50 m quadrats (belt transects) were tallied according to species and life <br />stage as either seedling, mature, or dead. The presence of dead individuals was recorded but did not <br />contribute to woody plant density calculations. <br />Lifeforms Used in Data Presentation <br />To enhance understanding of the collected data, all data and summary tables are organized by lifeform. <br />Lifeform categories used here reflect both plant growth habit and provenance (place of origin). Categories <br />observed in 2012 were: native annual and biennial forbs, introduced annual and biennial forbs, introduced <br />annual grasses, native perennial forbs, introduced perennial forbs, native perennial grasses and <br />graminoids, introduced perennial grasses, native shrubs, native subshrubs, native trees, native vines, <br />bryophytes (mosses), lichens, succulents and fungi (basidiomycete mushrooms). <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 the <br />cover sample transect were noted as present. Frequency for each plant species observed during <br />sampling was calculated by dividing the number of sample transects in which the species was observed <br />by the total number of samples (see cover sample distribution by area above). As such, this value is <br />probably more correctly known as constancy. <br />The total number of species within each lifeform observed in each 100 square meter sample provides a <br />measure of "species density ", indicating the relative species richness of different areas. This measure <br />provides a means of examining progress toward the return of diverse species composition in the <br />reclaimed areas. <br />Plant Species Listing <br />Scientific names used except as noted follow Weber and Wittmann (2001); common names cited are <br />found in 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 D of this <br />report. <br />3 <br />
