In addition to "first hit" data (the first interception of any of the above materials as a <br />point is projected from above), "additional hit" data (any additional live species <br />intercepted between the first hit and the ground) were collected. First hit interceptions <br />were used to calculate absolute top layer foliar cover (see FIRST HIT AVERAGE <br />COVER column in data tables) by dividing the number of interceptions for a particular <br />species or material by the total number of points taken (100). First hit relative <br />vegetation cover was calculated by dividing first hit absolute cover for each species by <br />the total first hit vegetation cover (see FIRST HIT RELATIVE VEGETATION COVER <br />column in data tables). All-layer absolute cover (see ALL HIT AVERAGE COVER <br />column in data tables) was calculated by dividing all hits for particular species by the <br />total number of points taken (100). In addition, all-layer relative cover was calculated <br />using all hits for particular species divided by the total vegetation hits accumulated <br />during sampling of the transect (see ALL HIT RELATIVE VEGETATION COVER <br />column in data tables). <br />Herbaceous Production Sampling <br />In 2013 Herbaceous production sampling was not collected in the 2011 Reclaimed <br />area. Since the area has only had two years of growth it is too young for clipping. <br />Lifeforms Used in Data Presentation <br />As a tool to enhance understanding of the collected data, the contents of all data and <br />summary tables are organized by lifeform. Lifeform categories used here reflect growth <br />habit and provenance (place of origin). Lifeform categories used include the following: <br />native annual and biennial forbs, introduced annual and biennial forbs, introduced <br />annual grasses, native perennial forbs, introduced perennial forbs, native perennial <br />cool season graminoids (includes grasses and grass-like plants), introduced perennial <br />cool season graminoids, native shrubs, native trees, bryophytes, lichens, and <br />succulents. <br />Plant Species Frequency and Density Measurements <br />During the course of cover sampling, all plant species occurring within one meter of <br />either side of the cover sample transect were noted as present. Frequency for each <br />plant species observed during sampling was calculated by dividing the number of <br />2 <br />
