<br />material when placed over tailing and evaluate the use of amendments such as <br />wood chips, straw, and sewage sludge, and the success of different <br />fertilizer schemes (the success of the Urad Mine tailing reclamation program <br />is very encouraging), (2) revegetate the rock material on slopes similar to <br />those expected on the open pit waste rock dumps, and (3) revegetate the rock <br />and exposed subsoil material above timberline using a native alpine seed <br />source in combination with a number of different mulching and fertility <br />treatments. <br />Research will concentrate on providing methods and materials to revegetate <br />exposed rock material within the open pit with native alpine s~~ecies so as <br />to restore the open pit slopes to a alpine talus landscape. <br />Since topsoil will be available only in limited amounts for reclamation <br />purposes, plots were established to determine the most efficient utilization <br />of it. Factors of interest were topsoil depth over tailing and topsoil <br />depths over waste rock both below and above timberline as related to growth <br />of both herbaceous and woody species. <br />With the above research goals in mind, Climax, in cooperation with Dr. Berg <br />(CSU), the High Altitude Revegetation Conmittee (Dr. Cuany of CSU), Dr. Ray <br />Brown of United States Forest Service, Forest and Range Experiment Station <br />(Logan, Utah), Dr. Cyrus McKell of Utah State University, and Dr. Beatrice <br />Willard of Colorado School of Mines, will test and evaluate adaptability of <br />native alpine species for revegetation purposes in the alpine tundra and <br />their applicability in conjunction with specific reclamation practices at <br />the Climax sites. <br />9.1.8 Research on Uptake of Heavy Metals by Vegetation Growing on Waste <br />During 1979, Climax initiated research at the Urad and Henderson mine sites <br />to obtain a quantitative assessment of vegetation success. 1'he initial <br />research was conducted by M.J. Trlica of CSU, and will be reeval~~ated every <br />three years. <br />16 <br />
