Forests in Central Europe continue to face severe stress from cumulative drought and extreme heat. In Slovakia, the National Forestry Centre reports that western and central regions—specifically mountain ranges such as Malé Karpaty, Považský Inovec, Tribeč, and Štiavnické vrchy—are in critical condition. The cumulative effect of multi-year drought is depleting tree reserves, leading to crown dieback in beech trees at scales not seen in recent decades. While deciduous trees like beech and birch show premature yellowing, shallow-rooted conifers like spruce are dying rapidly, increasing the risk of secondary pest infestations such as bark beetle outbreaks. In Germany, the situation includes increased fire risks and significant ecological shifts. In Thuringia, forest fire frequency has risen above historical averages. In Bavaria, extreme heat has caused trees to enter an “emergency mode,” shedding leaves prematurely to protect nutrients or due to solar radiation burns. This loss halts photosynthesis, impacting the growth of both young and old trees. Experts note that since 2018, drought and bark beetles have caused over 11,000 hectares of forest to die in certain areas. Consequently, foresters are shifting toward restructuring forests by removing species like spruce and pine to make way for more resilient types. In Austria, record heat has impacted biodiversity hotspots like North Rhine-Westphalia, drought conditions are impacting soil moisture levels. Data from the Lobau Helmholtz Centre for Environmental Research indicates that while northern areas maintain normal moisture, central and Seewinkel regions. Forest owners face high risks from spruce bark beetle southern regions, including areas around Düsseldorf and copper scavenger infestations. Additionally, Duisburg, are experiencing moderate to severe drought at depths of up to 1.80 meters. Recent rainfall has severely impacted been insufficient to replenish these deeper layers, posing risks to agricultural yields and increasing forest fire hazards. To address the mushroom foraging season due broader biodiversity crisis, where approximately 45 percent of investigated species in the region are threatened or extinct, the NRW-Stiftung has approved up to dry soil conditions. 300,000 euros for a nature conservation model project.
