In brief
The latest comprehensive assessment by the International Union for Conservation of Nature highlights the perilous state of tree species worldwide, with agriculture and logging identified as the primary threats.
A new assessment conducted by the International Union for Conservation of Nature (IUCN) has revealed alarming news: more than a third of the globe's tree species are currently at risk of extinction. This unprecedented evaluation serves as a critical reminder of the essential role trees play in sustaining life on Earth, with numerous other species of plants, animals, and fungi relying on forest ecosystems.Grethel Aguilar, the IUCN’s director general, emphasized the significance of trees, stating, “Trees are vital for maintaining ecosystems, and millions around the world count on them for their survival and livelihoods.” The comprehensive study, which encompasses over 80 percent of identified tree species, indicates that a staggering 38 percent are threatened. The collaborative effort drew on the expertise of more than a thousand professionals from various fields and regions.Particularly vulnerable are island tree species, which often exist in small, isolated populations. This reality has led to island trees constituting the highest percentage of species endangered with extinction. Countries such as Madagascar, which harbors various threatened rosewoods and ebonies, and Borneo, which faces risks to 99 species of Dipterocarpaceae trees, reflect the global crisis. Cuba’s red-flowered Harpalyce macrocarpa, known locally as maiden’s blood, is also on the brink, with fewer than 75 mature individuals reported.The study highlights that the primary threats to trees include agriculture, logging, and urbanization, a warning that acknowledges the accelerating pace of deforestation and habitat destruction. Emily Beech, who heads conservation prioritization at Botanic Gardens Conservation International, underscored the urgency of addressing these pressing issues to safeguard global biodiversity.
