• 2007 to a depth of 3 feet. The fourth site had topsoil placed onsite in 2005; this same <br />plot was the one defoliated by grasshoppers and abandoned. <br />Regraded overburden (spoil) and reapplied topsoil were analyzed for pH, <br />chemistry, texture, electric conductivity, sodium adsorption ratio, and acid -base <br />potential. Results indicated a 'good- rated' suitability for all samples analyzed (data <br />available from Seneca Coal Company). Soils analyses indicated that the topsoils used in <br />this study were not deficient in nutrients. <br />The experiment was designed in consultation with the RMRS Biometrician. The <br />experiment was fully replicated at the reclaimed experimental sites, and the study <br />utilizes an analysis of variance (ANOVA) with sources of variation treatments consisting <br />of landscape fabric (fabric or no fabric) and irrigation (supplement rainfall with or <br />without irrigation). The experiment was designed to be analyzed separately for each <br />species. Each experimental plot or block includes 16 rows of plants, 8 rows of <br />serviceberry and 8 rows of aspen (Tablesl - Yoast and Table 2 IIW). Each separate <br />• landscape fabric treatment contains 12 individual trees or shrubs; half were irrigated <br />and half not irrigated. Plants for the experiment were selected to be of uniform size <br />before planting. The first year growth and physiological measurements were conducted <br />during the summer of 2008. Photos of the experiment plots are shown in the Appendix. <br />• <br />12 <br />
