The study deals with analysis of natural regeneration in the selected climax spruce stands in the Šumava Mts., southern Bohemia. Six transects of size 5 x 50 m2 situated at right angles to the contour lines were established. All individuals of tree regeneration to the height of 3 m were mapped using Field-Map technology. Tree species and total height of individuals were recorded. The amount of regeneration is relatively low; nevertheless, in average 1,493 individuals per ha occurring in the area is a sufficient number for the formation of complex tree layer of climax spruce stand. In the M12 and M13 plots, absolute numbers of tree regeneration individuals were relatively low (440 and 920 ind. per ha). Mean height values ranged from 56 cm (M12 – Picea abies) to 173 cm (M15 – Sorbus aucuparia). The distribution of individuals in height classes is unequal, often asymmetrical.
