lodgepole pine . In 1969, the Colorado State Forest Service be- gan species survival plots along Tenmile drainage. The only available seedlings at that time were White Fir and Blue Spruce. Neither species were adaptable to the elevation and survival was poor. Later survival plots have incorporated Englemann Spruce and Lodgepole Pine with excellent survival percentages of 80 percent. Englemann Spruce taken from the Fort Collins nursery and planted in September immediately lost all current growth due to the drop in nightly temperatures. It was found necessary to move seedling spruce to the higher elevations either while still dormant or early enough in the summer to acclimate the seedlings . During the summer of 1971 , 2, 500 Englemann Spruce and Lodgepole Pine were planted in the old clear cut areas in upper Tenmile Valley. The planting stock was purchased from the State Forest Service in tar paper pots ( 2" x 2" x 9" ) . Using potted stock there is no problem with transplanting shock as would be the case with bare root seedlings . In 1974 , Climax began a transplant-nursery program. Even though there has been some success with seedling establish- ment from State Forest Service stock, native tree and shrub transplanting appears to be the best way to revegetate the upper subalpine areas at Climax. The native species are better accli- mated to the adverse growing conditions at Climax. Seedling trees that are destined to be destroyed by landscape disturbances, such as advancement of the Mayflower Tailing Pond are transplanted to an area being revegetated or to the nursery for use at a later time. The nursery will enhance Climax ' s supply of native trees and shrubs to be used for future reclamation activities . 9 . 13 MYCORRHIZAL FUNGI RESEARCH In 1976 , AMAX began funding of a three-year research program to study the use of mycorrhizal inoculated conifer seedlings to revegaate the Urad Mine tailing .
