The objective of this thesis is using a series of field investigations to determine the status and potential of natural regeneration of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) on the area of interest "The Forests of The City of Brno, Corp.". Based on the results of field investigations we can deduce on fertility of Douglas fir, status and parameters of natural regeneration, intervals of seed years and dispersal possibilities of natural regeneration from the parent growth. The work consists of two different parts, theoretical and methodological (practical). The first part analyses theoretical aspects of the solved issue and the second part is devoted mainly to the methodological procedures. Of the 100 analyzed growths was located 86 % on nutrient habitats. In 77 % of cases occurred in the growths Douglas fir as wood disseminated. All growths over 80 years are spawning: 33% slightly, 58% moderate and 9% richly. Without natural regeneration was recorded only 17 % of growths. The height of Douglas fir grow under vegetation of 1,3 meters can be expected in the age of 11--12 years.
