ti Climax Mine Permit No. 77-493 1982 Annual Report Page Two 4. The Plant Utilities and Services Relocation Project which includes replacing the old lime and sodium silicate mixing facility for purposes of improving efficiency. As with the overall operation, the level of reclamation work during 1982 was also reduced. However, our reclamation effort to date continues to be far ahead of our commitment as described in the timetable (Section 6 ) and the reclamation plan (Section 10 ) portions of the amendment. More than 1,000 acres have received vegetation attention during the past approximately 16 years. Some of the revegetated acreage is in excellent condition; all of it progressively improves with each passing year. Precipitation was above average through- out the 1982 growing season and revegetated areas responded accordingly. Areas seeded during 1982 included the topsoil stockpile adjacent to the park across from the gatehouse; some reseed- ing within the park itself; the construction disturbance created by the Storke Level Wastewater Plant Project; some areas along both the east and west tailing delivery lines, and some disturbance along the old stork access road. The slowdown has not significantly affected our mining and reclamation plans or timetables. Waste rock dumping in McNulty Gulch occurred at a reduced rate in 1982. Timber has been cut and most of the area prepared for the entire dump. The slowdown in mining allowed a suspension of activities on the Bartlett Mountain haul road construction and the lower levels project. Construction of the Spill Prevention Dam has not been initiated. A field evaluation of the major high-altitude revegeta- tion research plots established in 1978 was conducted by Dr. Fred Glover, an independent consultant from Fort Collins, Colorado. Results of the trial rows on the alpine disturbed soil plots on the ridge above McNulty Gulch indicated the most successful species to be Festuca ovina (Durar) , Poa alpina, Agropyron trachycaulum, Festuca rubra (Pennlawn) , Phleum alpinum, and Poa glauca. Results indicated the most successful species on the replicated alpine disturbed soils plots to be Poa alpina, Festuca thurberi, Trisetum spicatum, Agropyron trachycaulum, Deschampsia caespitosa, and Phleum alpinum. Evaluation of the level waste rock plots indicated the most successful species to be Linaria sp. , Festuca thurberi, Daucus carota, Phleum alpinum, Poa alpina
