recognition of its perennial habit compared to the C. carinatus taxon described in Weber and Wittmann <br />(2001) which is an annual. <br />Photographic Record <br />Within each area, representative color photographs were taken to document the appearance of the <br />vegetation in 2011 and 2012 (Appendix F). Where appropriate, a placard identifies the particular area and <br />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 <br />rim (dxl2 <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 freedom (infinite <br />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 />
