secunda are the plants formerly known as big bluegrass (Poa ampla) that were included in the <br />seed mixes as such. The taxonomic treatment of Weber and Wittmann (1996) places Poa ampla <br />(as well as Poa sandbergii) with Poa secunda. Despite this merger, the distinctness of Poa <br />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 2010 (Appendix 4). Within each reclaimed area <br />photograph, a placard identifies the particular area and sample. <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 and transects were randomly oriented; production <br />samples were located randomly behind the transect origin. At each cover/woody plant density <br />sampling location, the slope, expressed as a percent, and aspect of the site, in degrees not <br />corrected for magnetic declination, were determined and recorded, as was the orientation of the <br />transect. <br />Assessment of Reclamation Adequacy <br />GENERAL <br />Formal (statistical) hypothesis testing (see below) was undertaken for the Phase II Bond Release <br />Block. <br />SAMPLE ADEQUACY DETERMINATION <br />Sample adequacy was evaluated based on total live allowable herbaceous cover by vascular <br />plants using the following expression: <br />t 2 S 2 <br />nm ld x\ <br />where: <br />nm = minimum sample size <br />s2 = Sample variance (n-1 degrees of freedom) <br />4
