Tree growth response to drought partially explains regional-scale growth and mortality patterns in Iberian forests|森林生态数据集|干旱影响数据集

To quantify responses to drought from different data sources we take advantage of an extensive network of cross-dated tree-ring data with increment cores from 16 tree species sampled across the Spanish Iberian Peninsula (hereafter abbreviated as RWI-net), and of the Spanish National Forest Inventory (hereafter abbreviated as NFI) sampling tree and plot level data each km in forested areas. We selected the five most severe droughts that have affected each selected RWI-net population in the period 1981-2005 and calculated drought impacts on growth. For each site, we calculated drought-induced cumulative growth reductions (CDI, cumulative drought impact) as the summed impact of the selected droughts on growth of each population. A total of 334 RWI-net sites with chronologies that covered the period 1981-2005 for the 16 species, were finally used. For 192 of these RWI-net sites, 1883 NFI plots were found at distances < 10 km. The tables provided contain information on the sites and tree species in the RWI-net sites, as well as on drought impacts on growth, cummulative growth reductions and NFI growth, ingrowth and mortality.
