1.0 OBJECTIVES <br />-• A revegetation research program was initiated at Atlantic Richfield <br />Company's Mt. Gunnison Mine in the fall of 1977. This research is being <br />• conducted to determine methods to successfully revegetate coal refuse <br />disposal areas resulting from a coal preparatory plant that will be <br />located at the mine site. This research has been designed to answer the <br />• following questions: <br />1) Does the replacement of soil materials on coal refuse signifi- <br />cantly affect reclamation success? <br />2) Does one grass seed mixture (or shrub species) have signifi- <br />cantly greater success than another? If so, what planting <br />conditions contribute to this difference? <br />3) Is one grass seeding (or shrub planting) method significantly <br />better than another? If so, what conditions are responsible <br />for this difference? <br />4) Do soil and refuse material temperature and moisture regimes <br />vary sigai.ficantly due to soil material placement or seeding <br />method? If so, is germination and seedling establishment <br />directly affected? <br />5) Can 2:1 slopes be successfully stabilized using revegetation <br />methods proposed in Atlantic Richfield Company's mining and <br />reclamation plan for the .yt. Gunnison tline? <br />In conjunction with this program a sedimentation study was initi- <br />ated to evaluate the erosion control efficiency of various revegetation <br />i <br />~ treatments. <br />.~ <br />~..- <br />1 <br />
