The aim of this work is to determine the area of canopy gaps by aerial laser scanning and to analyse the frequency and intensity of trees growth responses to releases in past periods by reconstructing the disturbances using dendrochronological methods. In the Badínsky prales NNR, there is currently only a small proportion of gaps in the category with succcesional stand to 1/3 of the upper height of the stand (2%). As 23.4% of the NNR area is in the category with successional growth up to 2/3, we can assume more significant disturbances in past periods. Individuals located in the overstory have responded to releases in the past with greater growth change, which is essentially the reason for their current status. Intensive raction was marked in growth of firs, which, even at an advanced age, were able to change their diameter increment in some cases by more than 20 times. The high intensity disturbances were captured both by aerial scanning and by dendrochronology, as they conditioned a significant growth change of the released individuals. However, based on incremental changes, we also identified periods with extensive disturbances of lower intensity.
