The territory that was disturbed in the course of mining activities by the extraction of burnt clays (porcellanites) represents a relatively limited variant of the formation of Anthroposols for forestry purposes in the North Bohemian Brown Coal Basin. The evaluation of the development of soil properties and growth vitality of forest tree species that was conducted at this site covers the area of the former quarry of porcellanites in Želénky, 39 ha in size, that was reclaimed by fertilizable soils and tree species from man-made planting (Fraxinus excelsior L., Acer pseudoplatanus L., Larix decidua L., Quercus robur L., Tilia cordata Mill., Alnus glutinosa L. Gaertn., Picea pungens L.) and the area without porcellanite overlaying, influenced by up to the 25-year soil-forming process and tree species coming from succession (Acer pseudoplatanus L., Betula pendula Roth., Quercus robur L., Carpinus betulus L., Populus nigra L., Populus tremula L., Salix caprea L.). The ongoing soil-forming process on Anthroposols formed of porcellanites only is only characterized by an increase in the physiological depth of soil profile, content of fine earth (particles <2 mm), organic matters, soil acidity and cation exchange capacity and by a decrease in sorption saturation. All tree species from man-made planting show very good growth vitality on plots overlaid with fertilizable soils; the development of the tree species coming from succession on Anthroposols composed of porcellanites can be described in a similar way.
