In 1992 the Alberta Research Council initiated a reclamation study at the Smoky River Coal Limited No. 12 Mine South area located northwest of Grande Cache, Alberta. The objective of the research is to assess the potential for revegetation of land affected by surface coal mining in this alpine area. Two plot areas approximately 300 m apart were established on a south-west facing slope to evaluate the suitability of two different "soil materials". These included "coversoil" or the indigenous soil material and "rock spoil" material. A total of 18 plots were established at each of the two locations to evaluate the suitability of Highlander slender wheatgrass (Agropyron trachycaulum), alpine bluegrass (Poa alpina), broadglumed wheatgrass (Agropyron violaceum), and sheep fescue (Festuca ovina) for revegetation in this area. Plot seeding was completed in September, 1992 and selected plots were fertilized with the equivalent of 125 kg/ha of 35-15-0 in June 1993. Automated climate monitoring stations were installed ...
