Basic task of the biological stage of forest-directed reclamation of post-mining soilless areas is to speed up the growth of introduced plantations and stimulate soil-forming processes. During the reclamation, through technical and biological procedures the properties of initial soils are formed. Such properties have crucial influence on the value of the restored forest ecosystems. The goal of the carried out studies was to define the influence of four tree species on the properties of the initial soil, 8 years after the forestation of the waste heap of sterile rocks from the copper mining. In the paper the results referring to the accumulation of organic matter, organic carbon and nitrogen were presented as well as the selected physical and chemical properties of the studied initial soil. The obtained results indicate dynamic course of soil processes on the studied waste heap. This can be proved by the formation of characteristic for initial forest levels of accumulation already containing significant quantities of nitrogen-rich organic matter. In the layer 0-10 cm, the trend of favourable changes has appeared. This includes volume density, pH reaction and the content of nutrients. At the present stage of the development of initial soil the influence of the species composition of the forests could only be clearly seen in the accumulation of the organic matter and nitrogen.
