• years with drought conditions. After three full years of treatment, surviving trees were <br />expected to thrive without further control of competing vegetation and /or irrigation. <br />Examination of the plots in late 2008 confirmed these expectations. <br />This study: <br />Based on the findings of the preliminary study, a follow -up study reported here <br />was initiated in the fall of 2007 to determine if landscape fabric could be used <br />successfully to control competing vegetation and allow reproduction of aspen and <br />serviceberry woody perennials on reclaimed surface coal mine lands. A detailed <br />description of the study follows. <br />Objectives: <br />The overall objective was to develop improved technologies to address issues <br />related the growth and survival of perennial vegetation on reclaimed surface coal mine <br />• lands. The research was to find ways to improve the survival and quality of aspen and <br />serviceberry planted on reclaimed mine lands. Specific objectives were to: <br />1. Determine growth and survival of aspen and serviceberry with or without <br />control of competing vegetation using landscape fabric and with or without <br />supplemental irrigation on reclaimed surface mined lands at a western Colorado site. <br />2. Quantify physiologic condition of the plants under the control of competing <br />vegetation and irrigation treatments. <br />Experimental Procedures /Methodoloeies <br />Study Design: <br />The goal of this research was to identify operational effective planting and <br />control of competing vegetation techniques to reestablish self- sustaining woody <br />perennials on reclaimed mine lands that sustained native trees and shrubs before <br />mining. Findings from this study are applicable throughout the U.S. where planting <br />machines are commonly available and woody perennials are grown on reclaimed <br />0 <br />0 <br />
