The present paper describes the reclamation of dumpsites of coal ash - coal combustion by-products (CCB) generated by the burning of brown coal in thermal power plants. It evaluates the soil properties of formed Anthroposols and growth vitality of the forest tree species Quercus robur, Quercus rubra, Pinus sylvestris, Betula verrucosa, Populus tremula, Populus nigra, Salix fragilis, Salix alba and Alnus glutinosa. The best growth vitality at these sites was reached in tree species of seed origin from the vegetation series of primary succession. Deformations of the taproot (taproot laterals) in trees under 10 years of age were observed on Anthroposol from coal ash in Salix alba, S. fragilis, Populus tremula, P. nigra and P. alba, and in the overlaying of the compacted stabilizate with a layer of reclaimable soil up to 0.5 m in Pinus sylvestris, Alnus glutinosa and Quercus rubra.
