included in the seed mixes as such. The taxonomic treatment of Weber and Wittmann (1996) <br />places Poa ampla (as well as Poa sandbergh) with Poa secunda. Despite this merger, the <br />distinctness of Poa ampla is worth noting. <br />Photographic Record <br />Within each reclamation and reference area, representative color photographs were taken to <br />document the appearance of the vegetation in 2014 (Appendix 4). <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. Cover transects were randomly oriented. At each cover/woody <br />plant density sampling location, the slope, expressed as a percent, and aspect of the site, in <br />degrees not corrected for magnetic declination, were determined and recorded, as was the <br />orientation of the transect. <br />Assessment of Reclamation Adequacy <br />GENERAL <br />Formal (statistical) hypothesis testing was undertaken for percent allowable herbaceous cover in <br />the Phase II BRB PSCM —3 area (see below). <br />SAMPLE ADEQUACY DETERMINATION <br />Sample adequacy was evaluated based on total allowable live herbaceous cover by vascular <br />plants using the following expression: <br />t2s2 <br />n,,, (d x)2 <br />where: <br />nm = minimum sample size <br />s2 = Sample variance (n-1 degrees of freedom) <br />d = Precision (0.10 for cover and production; 0.15 for <br />woody plant density) <br />x = Sample arithmetic mean <br />4 <br />
