Scientists have revealed alarming news regarding the health of the world’s tree population, indicating that over a third of tree species are now at risk of extinction. This new data shows that tree species facing potential extinction far outnumber all threatened bird, mammal, reptile, and amphibian species combined. The findings were disclosed during a meeting in Cali, Colombia, where global leaders gathered for the UN biodiversity summit, COP 16, aimed at evaluating progress on a significant conservation plan.
Trees play a crucial role in maintaining ecological balance, as they help purify the air, capture carbon emissions, and provide habitats for countless species of wildlife. The assessment involved more than 1,000 scientists and was coordinated by the plant conservation organization Botanic Gardens Conservation International (BGCI) alongside the International Union for Conservation of Nature (IUCN). Emily Beech from BGCI emphasized that 38% of the world’s tree species are now threatened and highlighted the need for focused conservation efforts.
The primary dangers to trees include land conversion for agriculture and logging activities, while in temperate zones, pests and diseases contribute significantly to their decline. Notably, famed tree species such as magnolias, oaks, maples, and ebonies are among those most at risk. Efforts are being made globally to conserve these precious species, including initiatives by scientists at the Royal Botanic Gardens, Kew, who are gathering seeds and cultivating tree specimens in arboretums.
Conservation researcher Steven Bachman expressed his concern regarding the dire situation, stating that the loss of tree species could lead to the extinction of many other plants and animals dependent on them. The update to the extinction red list also included disturbing news for other wildlife, such as the hedgehog in Europe, which is facing habitat loss due to agricultural expansion, and various migratory shorebirds in the UK that are becoming increasingly endangered.
At the COP 16 summit, leaders are reviewing efforts to meet a goal of protecting 30% of the world’s land and marine environments by 2030. The summit is set to conclude on November 1, with several important unresolved topics, particularly concerning financial support for global biodiversity preservation and enhancing national strategies for nature protection.
Despite the grim statistics, the active engagement of scientists and world leaders during COP 16 presents an opportunity for meaningful change. With enhanced awareness and collaborative efforts, there remains hope that concerted actions can reverse the trends of decline and forge a path toward preserving critical tree species and biodiversity for future generations.
