Story summary

Global forests are shifting toward fast-growing tree species, reducing biodiversity and ecosystem stability.
A study by Aarhus University analyzed more than 31,000 tree species and found slow-growing trees critical for carbon storage are at extinction risk, especially in tropical and subtropical regions.
Human activities, including logging and climate change, worsen this trend.
Jens-Christian Svenning urges forest-management strategies that prioritize slow-growing species to boost diversity, resilience, and carbon storage.
