In Europe, by the end of the century, the number of tree species suitable for combating forest loss could be reduced by a third due to climate change. A study published in "Nature Ecology & Evolution" raises alarm. The findings suggest that some trees could be at risk even in a mild climate change scenario. The death rate of European trees has increased dramatically over the past three decades, forcing authorities to think about how to preserve forest ecosystems. Johannes Wessely of the University of Vienna in Austria and colleagues assessed the distribution of 69 native tree species in Europe, including ash, oak, willow and rowan, both in the wild and in plantations. The scientists then modeled their ability to survive until the end of the century based on three climate scenarios such as representativeness, concentration, landscape. (Vuac on agi.it)
