Forests in Central Europe are experiencing significant stress due continue to extreme heat face severe stress from cumulative drought and drought. extreme heat. In Slovakia, the National Forestry Centre reports that western and central regions, particularly regions—specifically mountain ranges such as Malé Karpaty, Považský Inovec, Tribeč, and Štiavnické vrchy—are in critical condition. The most severe impacts occur on south-facing slopes with shallow soil, are facing critical conditions. soil and declining groundwater levels. Deciduous trees like beech and birch are showing signs of distress, premature summer yellowing and leaf drop, while shallow-rooted conifers such as like spruce are dying rapidly. This cumulative drought depletion of tree reserves has led to crown dieback in beech trees on a scale not seen in recent decades, increasing the risk of weakening natural defenses against bark beetle outbreaks. Similarly, in Bavaria, In Germany, forestry experts report premature leaf loss caused by intense solar radiation and heat. Trees may enter an “emergency mode” the situation has evolved to redistribute nutrients or suffer direct leaf burns. This loss of foliage prevents photosynthesis, which stunts include increased fire risks and safety concerns. In Thuringia, the growth number of young trees forest fires recorded between March and impacts August 2026 reached 47, exceeding the trunk diameter historical average of older trees, potentially causing irreversible damage 28. While the total area burned is lower than in previous years, the frequency of incidents remains high. Climate change is significantly impacting tree vitality; for example, spruce populations in certain areas decreased from 38 percent to 31 percent between 2012 and 2022. Experts warn that multi-year drought phases prevent forest health. recovery even during rainy years. Additionally, drought-stressed trees are increasingly prone to instability, leading experts to advise hikers to watch for falling branches.
