Map of study area, showing Seneca Coal Company IIW and Yoast <br />plantings, south of Hayden, CO. <br />Aspen and serviceberry were planted using standard landscape fabric designed for <br />machine planting as recommend by the Colorado State Forest Nursery. This experiment <br />hand planted the trees and shrubs and hand-laid the landscape fabric, using the same 1.8 <br />m (6 ft) wide by 91 m (300 ft) rolls of landscape fabric, and 1.5 m (5 ft) tree/shrub <br />spacing within the row as used with machine planting. This particular experiment was <br />hand planted since the study was too small to warrant the economics of contracting for a <br />planting and fabric laying machine, and students were available to assist with the <br />planting. Trees were planted first then fabric was laid simulating techniques used where <br />trees and shrubs are first planted from the back of a tractor, followed by tractor-mounted <br />rolling and laying of the fabric, then slitting and pinning the fabric around and over the <br />planted trees. The experiment included a total of six plots, three at the IIW Mine and <br />three at the Yoast Mine. All of the plots were located within two fenced areas at each <br />mine to exclude elk, deer, and cattle browsing. At each mine, one of the fenced areas <br />• included one experimental plot and the other fenced area included two experimental
