which sheep fescue differs morphologically from the native Festuca saximontana (Rocky Mountain <br />fescue) is very minimal. Here all occurrences in the reclaimed and reference areas have been called F. <br />saximontana. <br />Photographic Record <br />Within each area, representative color photographs were taken to document the appearance of the <br />vegetation in 2012 (Appendix F). Where appropriate, a placard identifies the particular area and sample. <br />Statistical Methods <br />Sampling was conducted at randomly located sites. Random sampling locations were generated using <br />ESRI ArcMap 9.3 software and Hawth's Analysis Tools for ArcGIS (Beyer 2004). Garmin GPS60 units <br />(accuracy to 3 m) and topographic maps were used in the field to locate random points. Cover and <br />woody plant transects were randomly oriented; production samples were located randomly behind the <br />transect origin. At each cover /woody plant density sampling location, the slope, expressed as a percent, <br />and aspect of the site, in degrees not corrected for magnetic declination, were determined and recorded, <br />as was the orientation of the transect. <br />Assessment of Reclamation Adequacy <br />GENERAL <br />Formal (statistical) hypothesis testing (see below) was undertaken for the Phase III Bond Release Block <br />(post -law, Permanent program lands). <br />DETERMINATION OF SAMPLE ADEQUACY <br />Sample adequacy for the data collected was evaluated based on total first -hit vegetative cover using the <br />following expression: <br />_ t z s _ <br />n m i td — x )2 <br />Where: n = minimum sample size <br />s = Sample variance (n -1 degrees of freedom) <br />d = Precision (0.10 for cover and production) <br />x = Sample arithmetic mean <br />t = The (a =.10) t -table value for a 1 tail t -test, n -1 degrees of <br />freedom (infinite degrees of freedom may be used if n >30) <br />n = Sample size <br />All such calculations were based on data from a minimum of fifteen samples. <br />4 <br />
