With ongoing global warming, increasing water deficits promote physiological stress on forest ecosystems with negative impacts on tree growth, vitality, and survival. How individual tree species will react to increased drought stress is therefore a key research question to address for carbon accounting and the development of climate change mitigation strategies. Recent tree-ring studies have shown that trees at higher latitudes will benefit from warmer temperatures, yet this is likely highly species-dependent and less well-known for more temperate tree species.

- - The study emphasizes the importance of high-resolution annual forest growth maps, using tree-ring width (TRW) data, to better understand forest carbon sequestration and the impact of climate change and drought on forest ecosystems.
- - By integrating high-resolution Earth observation data with climate and topography information, the researchers found that species-specific models could explain over 52% of variance in tree growth, enhancing the accuracy of growth predictions compared to using just climate and elevation data.
- - The research successfully generated a map of annual TRW for 2021, demonstrating that combining different data sources can lead to more effective models for forest growth, while also identifying areas where predictions may be less reliable, particularly in climate marginal zones.
The record-breaking drought in 2018 caused premature leaf discoloration and shedding (early browning) in many beech (Fagus sylvatica L.) dominated forests in Central Europe. However, a high degree of variability in drought response among individual beech trees was observed.
