<br />Seedling trees that are destined to be destroyed by landscape disturbances, <br />such as the advancement of the Mayflower Tailing Pond were transplanted to <br />an area being revegetated or to the nursery for use at a later time. The <br />nursery will enhance Climax's supply of native trees and shrubs to be used <br />for future reclamation activities. <br />Aspen <br />Aspen is an extremely desirable species because of its s~~i1-building <br />characteristics, its relatively rapid growth rate, and its rapid <br />colonization and spreading abilities. Through the years, many attempts have <br />been made to develop a method of producing quantities of aspen from <br />cuttings, but no quick and easy formula for success has been developed. The <br />Institute of Paper Chemistry in Appleton, Wisconsin, contributed a number of <br />hybrids for testing at high elevations 3,334 m (11,000 ft). Generally, they <br />survived for about two years, seemingly healthy and well established, then <br />died out. The genetics of these varieties were probably not comF~atible with <br />the climate. Test plots of aspen planted at the Henderson mill site in 1971 <br />and 1972 were failures. Experimentation with sprouts obtained fom root <br />cuttings of aspen in the area of the mill site have met with similar <br />results. <br />Direct transplant of aspen within the same area has met with varying success <br />(Figure 9-2). Aspen transplanted from nearby avalanche runs onto the rock <br />covering the Urad tailing generally survive the first winter, Iw t show no <br />new growth during the second growing season. Lack of growth during the <br />second season in this harsh habitat is to be expected. Aspen probably <br />requires 2-3 yr before aboveground growth. The overall 3-yr survival rate <br />is approximately 50 percent. <br />Willows <br />Cuttings of indigenous willows have been rooted in a greenhouse environment <br />(Figure 9-3) and transplanted to disturbed areas at the Climax and Urad <br />mines. Rooting techniques are being perfected, and the approach appears to <br />28 <br />
