The subject of the study was a dynamic population of Sorbus torminalis resulting from spontaneous regeneration from seeds in northern Poland. The population, occupying a fenced plot of 1.72 ha in Forest District Jamy, amounted to 579 individuals. The spatial structure of population and some basic individual traits of trees were recorded, then the growing space of individual trees was examined. The following measures of tree growing space were investigated: crown diameter and projection area, and tree volume. The spatial structure of population was non-random, and there was evidence for effects of population density on tree performance. The observations have to be continued in order to describe optimal growing space of wild service tree; the results could be used to improve in situ conservation of this rare and valuable species.
