Deciduous tree species are losing their ability to recover from drought stress

Climate change is driving more intense droughts, threatening global forests. This commentary highlights a pivotal study revealing an alarming trend: deciduous trees, long assumed to be resilient due to fast recovery, are losing this critical ability. Analysis of Canadian forests shows a century-long decline in deciduous drought recovery, while evergreens remain stable. This suggests a major shift in forest composition is underway, with profound implications for biodiversity, carbon storage, and ecosystem services. Urgent action is needed to integrate these findings into climate models and conservation strategies to safeguard our forests for the future.
