Abstract: Wild service tree belongs among rare woody plants tolerant to higher temperatures and low soil humidity. There are available data from analyses of 34 wild service tree localities in Slovakia. The majority of analyzed localities (70%) were on south-exposed stands (SE, S, SW); 97% of these were in altitudes up to 600 m. Wild service tree prefers biotopes of the oak-hornbeam forests. The highest frequency of this woody plant was found in group of forest site types Fageto-Quercetum. According to altitudinal vegetation stages, the majority of stands (85%) were in the 3rd and 2nd vegetation stage, where potential evapotranspiration is higher than the sum of precipitation. From March to September the water deficit is approximately 100-150 mm. The most frequent are stands with mountain climate (62%) with prevalence of moderately warm (38%) and warm (15%) climate. Wild service tree grows mainly on soils with favourable physical characteristics and adsorbing complex (65% of stands). The soils are fertile and well supplied with nutrients (Luvisols, Cambisols). Some localities (35%) have soils rich in minerals; however, their soil chemistry is one-sided, so they are mostly little fertile (Rendzinas). Regarding the water content in soils, Cambisols have generally sufficient water supply; Luvisols have lower water supply with a possibility of their aridization; Rendzinas are mostly loose soils with good permeability, regarding their shallow profile with lower water capacity they have usually less water supply. According to the obtained data, it is possible to evaluate wild service tree as a light-demanding woody plant with requirements for higher temperatures and higher contents of nutrients in soil, able to grow on drier soils with infrequent occurrence of water deficit. With regard to the expected changes of global climate, wild service tree should substitute some tender woody plants with higher sensitivity to drought in landscape as well as in forestry.
