• INTRODUCTION <br />Quantitative sampling of Woody Plant Density areas in the reclaimed areas at Seneca Coal <br />Company's (SCC) Seneca IIW Mine was undertaken on September 8, 2010 by ESCO Associates <br />to facilitate SCC's continued monitoring of the progress of these areas in relation to revegetation <br />performance standards. Methods, sample areas, and sample sizes were those specified by SCC. <br />METHODS <br />Woody Plant Density Area Sampling <br />Woody Plant Density areas and sample locations for the Seneca IIW Mine in 2010 are shown on <br />Map 1, "2010 Woody Plant Density Monitoring Locations - North Map" and Map 2, "2010 Woody <br />Plant Density Monitoring Locations - South Map" <br />Woody Plant Density samples were collected along 50 m transects. All trees, shrubs and <br />subshrubs with root crowns located within the boundaries of 2 X 50 m quadrats (belt transects) <br />were tallied according to species and life stages as either seedling, mature, or dead. The <br />presence of dead individuals was recorded but did not contribute to Woody Plant Density <br />• calculations. <br />Lifeforms Used in Data Presentation <br />To enhance understanding of collected data, all data and summary tables are organized by <br />lifeform. Lifeform categories used here reflect growth habit and provenance (place of origin). <br />Woody Plant categories observed in 2010 were: native trees, native shrubs and native <br />subshrubs. <br />Plant Species Listing <br />Scientific names used follow Weber and Wittman (1996); common names cited are found in <br />Beetle (1970), Nickerson et al. (1976), or Soil Conservation Service (1979). Note that all big <br />sagebrush plants encountered were referred to as Seriphidium tridentatum. <br />Statistical Methods <br />Sampling was conducted at randomly located sites. Random map points for sampling locations <br />were generated randomly using ESRI ArcMap 9.3 software and Hawth's Analysis Tools for <br />ArcGIS (Beyer 2004). Garmin GPS60 units (accuracy to 3 m) and topographic maps were used in <br />the field to locate random points. <br /> <br />1
