done in accordance with approved mine reclamation practices, with the exception that hand spot-spraying of <br />broadleaf weeds will need to be done to avoid damage to aspen transplants. <br />Trees to be transplanted will be selected from along the edges of successfully suckering clones on Seneca <br />property. Aspen suckers growing at the edges of existing clones are more likely to have smaller, more <br />independent roots than those that arise along older connecting roots between large trees. Transplant <br />candidates will be 4-6 ft. in height, without forks, disease, or damage that might affect survival. Trees will be <br />dug and balled with as much soil as possible to maximize root biomass. After discussions with Seneca staff <br />concerning the difficulty of operating equipment on saturated soils in early spring, we decided that all aspen <br />saplings will be dug and balled after leaf fall in October, held in dormant condition in mulched beds over winter <br />and transplanted before bud-break in the spring. Trees will be planted in individually dug holes in topsoil that <br />was re-deposited on the mined site. Each tree will be staked to prevent wind-tip. To help balance root/shoot <br />ratios and transpiration loads, each tree will also be pruned from the bottom so that only the terminal leader <br />and one whorl of lateral branches remain. Soil surrounding each transplanted tree will be thoroughly soaked at <br />the time of planting to insure good initial root contact with the soil. <br />Drip systems will be installed immediately after planting, with an emitter running to each tree. Self-cleaning, <br />pressure compensating emitters will be used to insure equal amounts of water are delivered to each of three <br />watering treatments in the plantation. A suggested layout for the experiment appears below: <br />Tank <br />Normal Valves Modified <br />Topsoil ~ Fence Topsoil <br />{320' x 100} <br /> <br />3 water levels + control x 2 soil types, 50 trees each, 5'x5' spacing <br />To insure a working pressure of 50 psi, the water storage tank should be installed at least 115 vertical feet <br />above the valves. To minimize friction pressure loss, one-inch poly hose will be used to feed the valve <br />manifold, and '/. inch line used to each water treatment. Emitters will be installed on ten Y: inch feeder lines in <br />W'.~YPp rnw/Fev. IIIGI PM1pi/App~ix ISJ <br />i/DIOiM <br />
