Abstract : Compilation of climatological data aids in developing revegetation plans. Weather stations near the site to be revegetated should be consulted and seasonal rainfall and temperature patterns obtained. This information should be utilized to plan the plant species to be used and to schedule revegetation operations. Comparison of the solar irradiation loads for different slope aspects and inclinations quickly identifies high radiation areas. Reduction of slope angle and controlling the aspect can be greatly reduce the solar load. Then engineering designs necessitate high radiation loads, the severity of the solar environment can be mitigated by the use of drought and high temperature resistant plant species. Providing a rough microterrain can also provide shade for young specimens as the vegetation becomes established. It is further recommended that different seed lists be considered for harsher sites (such as southfacing slopes) that receive high radiation loads. Soil analyses are critical when preparing a seed list. Analyses identify problematic soil conditions which may be tolerated by some, but not other plant species. The use of nontolerant species can result in barren areas, subject to erosion and dust hazards. Furthermore, is analyses show severe problems in chemical or physical factors, corrective ammendments of topsoiling may be required to ensure revegetative sucess.
