The true response of Fagus sylvatica L. to disturbances: A basis for the empirical inference of release criteria for temperate forests

Popis výsledku v původním jazyce

Because of some arbitrary decisions in recent dendrochronological research on forest disturbance. histories, describing the actual growth responses of trees to disturbance events is still an issue of great importance. This is even more important in temperate beech-dominated old-growth forests driven by fine-scale disturbances, where a majority of growth pulses occur close to the arbitrary threshold of release detection. Recognizing this limitation, we provide a new empirically-based release detection criterion on the basis of actual reactions of trees to independently dated disturbance events interconnecting three data sets-tree censuses, dendrochronology and historical aerial photographs. The growth response of Fagus sylvatica L. was studied in detail in relation to the canopy position of surviving trees as well as regional climate responses, using 280 increment cores extracted in 8 old-growth forests in the Czech Republic. Our results imply relatively high uncertainty in the detection of disturbance using dendrochronology, which can be troubled particularly in spatial analysis of past disturbances. We believe that our empirically-derived criteria represent a substantial contribution to further dendroecology research, with broad applicability to a wide range of beech-dominated temperate forests.
