Climate model projections suggest widespread drying in the Mediterranean Basin and wetting Fennoscandia coming decades largely as a consequence of greenhouse gas forcing climate. To place these other "Old World" climate into historical perspective based on more complete estimates natural hydroclimatic variability, we have developed World Drought Atlas" (OWDA), set year-to-year maps tree-ring reconstructed summer wetness dryness over Europe during Common Era. The OWDA matches accounts severe...
Abstract Tree mortality is a key factor influencing forest functions and dynamics, but our understanding of the mechanisms leading to associated changes in tree growth rates are still limited. We compiled new pan‐continental tree‐ring width database from sites where both dead living trees were sampled (2970 4224 190 sites, including 36 species), compared early recent between that died those survived given event. observed decrease radial before death ca. 84% events. The extent duration these...
Abstract The growth of past, present, and future forests was, is will be affected by climate variability. This multifaceted relationship has been assessed in several regional studies, but spatially resolved, large-scale analyses are largely missing so far. Here we estimate recent changes 5800 beech trees ( Fagus sylvatica L.) from 324 sites, representing the full geographic climatic range species. Future trends were predicted considering state-of-the-art scenarios. validated models indicate...
Tree mortality is a key driver of forest dynamics and its occurrence projected to increase in the future due climate change. Despite recent advances our understanding physiological mechanisms leading death, we still lack robust indicators risk that could be applied at individual tree scale. Here, build on previous contribution exploring differences growth level between trees died survived given event assess whether changes temporal autocorrelation, variance, synchrony time-series annual...
Abstract Heatwaves exert disproportionately strong and sometimes irreversible impacts on forest ecosystems. These remain poorly understood at the tree species level across large spatial scales. Here, we investigate effects of record-breaking 2018 European heatwave growth water status using a collection high-temporal resolution dendrometer data from 21 53 sites. Relative to two preceding years, annual stem was not consistently reduced by but stems experienced twice temporary shrinkage due...

Under predicted climate change, native silver fir (Abies alba) and European beech (Fagus sylvatica) are the most likely replacement species for Norway spruce (Picea abies) monocultures planted across large parts of continental Europe. Our current understanding adaptation potential fir-beech mixed forests to change is limited because long-term responses two environmental changes have not yet been comprehensively quantified. We compiled analysed tree-ring width (TRW) series from 2855 dominant,...
The response of forest productivity to climate extremes strongly depends on ambient environmental and site conditions. To better understand these relationships at a regional scale, we used nearly 800 observation years from 271 permanent long-term monitoring plots across Switzerland, obtained between 1980 2017. We assimilated data into the 3-PG ecosystem model using Bayesian inference, reducing bias predictions 14% 5% for stem carbon stocks 45% 9% stock changes. then estimated forests...
Determining the drivers of shifting forest disturbance rates remains a pressing global change issue. Large-scale dynamics are commonly assumed to be climate driven, but appropriately scaled histories rarely available assess how legacies alter subsequent and sensitivity disturbance. We compiled multiple tree ring-based from primary Picea abies fragments distributed throughout five European landscapes spanning Bohemian Forest Carpathian Mountains. The regional chronology includes 11,595 cores,...
Abstract Broad‐scale forest die‐off associated with drought and heat has now been reported from every forested continent, posing a global‐scale challenge to management. Climate‐driven is frequently compounded other drivers of tree mortality, such as altered land use, wildfire, invasive species, making management increasingly complex. Facing similar challenges, rangeland managers have widely adopted the approach developing conceptual models that identify key ecosystem states major types...
Climatic constraints on tree growth mediate an important link between terrestrial and atmospheric carbon pools. Tree rings provide valuable information climate-driven patterns, but existing data tend to be biased toward older trees climatically extreme sites. Understanding climate change responses of biogeographic regions requires that integrate spatial variability in growing conditions forest structure. We analyzed both temporal (c. 1901-2010) variation radial patterns 9,876 from fragments...
Abstract The response of forest growth to climate variability varies along environmental gradients. A increase and decrease with warming is usually observed in cold‐humid warm‐dry regions, respectively. However, it remains poorly known where the sign these temperature effects switches. Here we introduce a newly developed European tree ring network that has been specifically collected reconstruct aboveground biomass increment (ABI). We quantify, how long‐term (1910–2009) interannual ABI...
FORMIT-M is a widely applicable, open-access, simple and flexible, climate-sensitive forest management simulator requiring only standard inventory data as input. It combines process-based carbon balance approach with strong inventory-based empirical component. The model has been linked to the global sector EFI-GTM secure consistency between timber cutting demand, although prescribed harvest scenarios can also be used. Here we introduce structure of demonstrate its use example simulations...
Forest models are instrumental for understanding and projecting the impact of climate change on forests. A considerable number forest have been developed in last decades. However, few systematic comprehensive model comparisons performed Europe that combine an evaluation modelled carbon water fluxes structure. We evaluate 13 widely used, state-of-the-art, stand-scale against field measurements structure eddy-covariance data over multiple decades across environmental gradient at nine typical...
