• All shrubs, including seedlings, with root crowns found within the quadrat boundaries were <br />tabulated by species and by life stages as follows: Seedling, Mature, or Dead. <br />Lifeforms Used in Data Presentation <br />As a tool to enhance understanding of the collected data, the contents of the cover and summary <br />tables addressing relative cover and species density, as well as the species presence tables, are <br />organized by Vifeform. Categories used include liieform in the usual sense with an indication of <br />provenance (place of origin). Categories used include the following: Native annual and biennial <br />forbs, Introduced annual and biennial (orbs, Native annual grasses, Introduced annual grasses, <br />Native perennial forbs, Introduced perennial forbs, Native perennial graminoids (includes <br />grasses and grass-like plants), Introduced perennial graminoids, Shrubs (all of these being <br />native at this site), Trees (likewise all native in the study area), and Ferns. <br />Plant Species Frequency and Density Measurements <br />During the course of cover sampling, all plant species occurring within one meter on either side <br />of the cover sample transect were noted as present within each sample. Frequency for each <br />plant species observed during sampling was calculated by dividing the number of sample <br />. iransects in which the species was observed by the total number of samples (see cover sample <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 percent. <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 Species Listing <br />During the course of the field work, a list of all encountered plant species (quantitative plus <br />incidental observations) was compiled for the sampled reclamation.
