In brief
The International Union for Conservation of Nature reports that 38% of tree species are threatened globally, predominantly due to agriculture and logging, with island biodiversity at particular risk.
More than a third of global tree species are facing the possibility of extinction, according to a groundbreaking assessment revealed at the United Nations Biodiversity Conference in Cali, Colombia. The International Union for Conservation of Nature (IUCN) released the findings, which reveal that 38% of tree species are now endangered.The assessment, deemed comprehensive, incorporates data from over 80% of known tree species, thanks to the contribution of more than a thousand global experts. Trees play a pivotal role in sustaining life on Earth, providing critical support to various ecosystems and serving as vital resources for millions of people. Grethel Aguilar, IUCN's director general, emphasized the importance of trees in maintaining ecological balance and human livelihoods.Island ecosystems are found to be particularly vulnerable, with unique tree species at a heightened risk due to their limited populations and habitats. For instance, Madagascar's rosewoods and ebonies are perilously close to extinction, while Borneo harbors 99 endangered Dipterocarpaceae species. In Cuba, alarming figures indicate that fewer than 75 mature individuals survive for the Harpalyce macrocarpa tree.The research indicates that the primary threats to tree populations worldwide stem from agricultural expansion and logging activities, with urbanization also contributing to habitat loss, as stated by Emily Beech of Botanic Gardens Conservation International. The urgency for comprehensive conservation efforts has never been more critical as the delicate balance of our planet’s biodiversity is under threat.
