The study deals with the localization of European beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L.) in spruce monoculture in the Bohemian Switzerland National Park (České Švýcarsko, Czech Republic). The coordinates of the investigated individual trees were localized by GPS for determining their distribution. Additionally, their quality and health state as well as the occurrence of natural regeneration under their crowns were determined. The located trees were recorded in maps within the program ArcGIS. The state of the trees indicated that the majority of them constitute an appropriate potential source of natural regeneration. Despite this, no natural regeneration of oak was found and beech natural regeneration occurred only among 9% of the investigated trees. Browsing is suggested as limiting factor for the beech and oak natural regeneration. According to the forest management plan of the national park administration, 22% of the stands should have already been regenerated, but this has not been reached until the time of the research. 41% of the stands have not achieved yet the appropriate age for regeneration. This has significant impact on the formation of natural regeneration. On the basis of the study, reproduction methods were proposed for an environmental-friendly and economically sound restoration.
