Service tree Sorbus domestica L. is one of the rare autochthonous woody plants. There are analysed data from 24 localities with service tree in Slovakia. They were found mainly in agricultural land (242 individuals) and just on 5 forest stands (22 individuals). Service tree stands were found on south-east, south and south-west exposures. More than 90% of them were on altitudes up to 400 m. The majority of the stands were found in the subtype of mostly warm plain climate, as well as in the subtypes of warm and moderate warm fold climate and mountain climate. In our country service tree grows on soils with favourable physical characteristics and adsorbing complex. The soils are fertile, well supplied with nutrients (Luvisols, Cambisols) on 96% of analysed stands. Some localities (4%) have soils rich in minerals, but the soil chemistry is one-sided, so they are mostly little fertile (Rendzinas). Regarding the water content in soils generally, Cambisols have sufficient water-supply. The Luvisols have lower water supply with possibility of their aridization. Rendzinas are mostly loose soils with good permeability, regarding their shallow profile with lower water capacity and good drainage of the parent rock they have usually less water supply. According to obtained data, it is possible to evaluate service tree as light demanding woody plant with requirements on higher temperatures and higher content of nutrients in soil. This woody plant is able to grow on drier soils with infrequent occurrence of water deficit. Regarding the expected changes of global climate, service tree should substitute some tender woody plants with higher sensitivity to drought within the landscape arrangements.
