Global Tree Extinction Threat Revealed; Over a Third of Species at Risk

An assessment by scientists regarding threats to the planet’s trees indicates that over one-third of all species are at risk of extinction in their natural habitats. The updated official extinction red list shows that the count of endangered tree species now surpasses the combined total of all threatened birds, mammals, reptiles, and amphibians. This information was disclosed in Cali, Colombia, coinciding with the UN biodiversity summit, COP 16, where global leaders are convened to evaluate advancements on a significant nature conservation initiative. Trees play a crucial role in sustaining life, contributing to air purification and carbon emission absorption, alongside serving as habitats for numerous birds, insects, and mammals. Over 1,000 scientists participated in this evaluation of tree conservation status, which was compiled by the plant conservation organization Botanic Gardens Conservation International (BGCI) and the International Union for Conservation of Nature (IUCN). Emily Beech from BGCI stated that 38% of the world’s tree species are currently endangered. She remarked, “Trees are highly threatened all across the world but now we have the tools that we need to make sure that we prioritise conservation action on the ground.” Tree species face risks in 192 nations, with agricultural land clearance and logging identified as the primary dangers, while pests and diseases pose significant threats in temperate zones. Prominent tree types, including magnolias, are listed among the most imperiled, alongside oaks, maple, and ebonies. Researchers at the Royal Botanic Gardens, Kew, located in London, are engaged in global tree conservation efforts through seed collection and cultivating specimens in arboretums. Steven Bachman, a conservation researcher, described the statistics as “shocking,” highlighting the cascading impact on numerous other plant and animal species reliant on trees. He stated, “We are currently in a biodiversity crisis. Many species of trees all around the world are providing habitat for many other species of birds, mammals, insects, fungi. If we lose the trees we are losing many other species with them.” In addition to trees, the revised extinction red list also presented concerning findings for other plant and animal species. The hedgehog (Erinaceus europaeus) has progressed further towards extinction, with its populations declining throughout large parts of Europe, including the UK. This widely cherished mammal is experiencing habitat loss because of expanding agricultural practices and land development. Furthermore, worries exist regarding the survival of migratory birds, a significant number of which utilize Britain’s extensive shorelines and estuaries as stopover points. Four specific UK shorebird species—the grey plover, dunlin, turnstone, and curlew sandpiper—are now categorized as increasingly endangered on the red list. During COP 16, global leaders are convening to evaluate the advancement made towards fulfilling a commitment to safeguard 30% of terrestrial, marine, and oceanic areas by 2030. The summit is scheduled to conclude on 1 November, with several unresolved matters remaining, such as funding for worldwide biodiversity preservation and strengthening national nature protection strategies.
