Trees face threat of extinction
AROUND a third of all the world’s tree species are threatened with extinction, according to a global index warning that climate change could tip some forests into ecosystem collapse.
Land clearance for farming – both crops and livestock – and logging were by far the biggest threats to trees, the State of the World’s Trees report said, adding that climate change was also “having a clearly measurable impact”.
The study looked at the risks to 58,497 tree species worldwide and found that 30 per cent (17,500) were threatened with extinction, with a further 7 per cent listed as “possibly threatened”.
Well-known trees such as magnolias were among the most threatened.
