Doctoral Research ProjectStructure and disturbance patterns of the largest European primeval beech forest revealed by terrestrial and remote sensing data Knowledge on large-scale dynamics of natural beech forests is limited, since such forests are rare and previous studies were focusing on relatively small areas. An outstanding object to study patterns and processes of natural beech forests over large spatial scales is the largest remnant of European beech (Fagus sylvatica L.), the primeval forest Uholka-Shyrokyi Luh in the Ukrainian Carpathians. The main objective of this thesis is to characterise the structure of this forest and its disturbance regime at different spatial scales. To do so, three methodological approaches were applied. At first, data of the main forest structural attributes gained in a (1) terrestrial sampling were used and supplemented with a (2) tree-ring assessment of the forest’s age structure and disturbance history. Subsequently, (3) high-resolution WorldView-2 stereo satellite images were applied to analyse canopy gaps over the entire forest area. The combination of these terrestrial, dendroecological and remote sensing approaches enabled the derivation of a conclusive picture of the structure and disturbance patterns shaping the primeval beech forest of Uholka-Shyrokyi Luh.
