<br />The principal investigator, Dr. Robin Cuany of the CSU Agronomy Department <br />was assisted by Mr. Steve Kenny, a graduate student. The project is being <br />funded by AMAX and the High Altitude Revegetation Committee including, <br />institutions such as ski areas, seed companies and governmental agencies. <br />Dr. Cuany has been conducting similar research on smooth brome, started at <br />Climax in 1970, in an effort to produce an improved high-altitude variety of <br />that species. <br />9.2.4 Species/Strain Testing, 1974 Plots <br />In 1974, Dr. Robin Cuany, CSU Agronomy Department, initiated sptacies/strain <br />tests at six alpine and subalpine locations, one of which was Located at <br />Climax. Dr. Cuany's research is in conjunction with the "Committee for <br />High-Altitude Revegetation" to which Climax is a major contributor. After <br />two years of growth, hard fescue, red fescue, and chewings fescue were well <br />established and beginning to spread, although early growth was slow. The <br />bluegrass did not establish as well as the fescues. The most vigorous large <br />grasses included 'Rosana' western wheatgrass, 'Primar' slender wheatgrass, <br />'Manchar' smoth brome, orchard grass, and Timothy. <br />In 1976, species/strain tests were initiated at five high altitude locations <br />in northwestern, northcentral and central Colorado, including Climax. Plots <br />evaluated in fall, 1976 showed that emergence was generally good for all <br />strains except Rocky Mountain perstemon, yellow sweetclover, alsike clover, <br />and zigzag clover. During 1976, native species were collected for <br />preliminary evaluation of breeding opportunities. The objective of this <br />program was to develop a native species seed source. <br />2.5 Native Species Study on Tailing 1976 <br />A preliminary field study was conducted on Climax tailing by Dr. Berg of CSU <br />and Henry Barrau, to evaluate the performance of some native grasses, (orbs, <br />shrubs and trees. All the plants and seeds used in this study were <br />collected within Climax property. The objectives were to (1) e~ialuate the <br />potential for seeding native species on Climax tailing and (2) determine the <br />survival and growth of native shrubs and trees transplanted on tailing. <br />33 <br />
