Trade-offs in productivity and drought resilience of five dominant tree species in the Central European temperate forest
Increasing frequency of droughts strongly affect the available soil water. Lower water availability was often reported to reduce radial growth not only in climate-limited, but also in optimal areas of tree species distribution. Sampling strategies in dendrochronology focus on specific sites, often in climate-limited conditions. Using tree ring samples collected within National Forest Inventories provides an opportunity to assess growth-climate responses statistically representative of the great variability in environmental conditions. A total of 859 tree ring cores from 5 dominant tree species of European temperate forests (Norway spruce, silver fir, Scots pine, European beech and sessile oak) were collected during the 2015 - 2016 cycle of the Slovak National Forest Inventory. To quantify the drought events, we used SPI of spring and summer period derived from CRU climate database. The results indicated a significant inter- and intra-specific variability in growth-climate responses across the environmental gradients. In addition, a difference in the radial increment recovery period was found between the species.
