A Combined Tree Ring and Vegetation Model Assessment of European Forest Growth Sensitivity to Interannual Climate Variability

Popis výsledku v původním jazyce

The response of forest growth to climate variability varies along environmental gradients. A growth increase and decrease with warming is usually observed in cold-humid and warm-dry regions, respectively. However, it remains poorly known where the sign of these temperature effects switches. Here we introduce a newly developed European tree ring network that has been specifically collected to reconstruct forest aboveground biomass increment (ABI). We quantify, how the long-term (1910-2009) interannual variability of ABI depends on local mean May-August temperature and test, if a dynamic global vegetation model ensemble reflects the resulting patterns. We find that sites at 8 degrees C mean May-August temperature increase ABI on average by 5,7 +/- 1,3%, whereas sites at 20 degrees C decrease ABI by 3,0 +/- 1,8%m(-2)year(-1) Delta degrees C-1. A threshold temperature between beneficial and detrimental effects of warming and the associated increase in water demand on tree growth emerged at 15,9 +/- 1,4 d
