DUBLIN — Some of the world’s most recognisable trees, including oak, magnolia and maple, are among the 30 per cent of species at risk of extinction, according to Botanic Gardens Conservation International (BGCI). Published on Wednesday, the BGCI’s State of the World’s Trees report warned that over 17,000 of the world’s 60,000 kinds of tree could soon be no more due to logging, forest clearances, farming and extreme weather. The most vulnerable are 440 species which “have fewer than 50 individuals remaining,” according to the report, which the BGCI said was based on five years of work involving 60 institutions and 500 researchers. Around one in five tree species are used by humans “for food, fuel, timber, medicines, horticulture,” the BGCI said, with only around 40 per cent of species confirmed as not at risk.
DUBLIN — A NASA-led research team has developed a “unique” satellite-based deforestation tracking system they hope could avert a “tipping point” for the world’s shrinking jungles. The plan is for the new “tropical vulnerability index” to enhance “early warning” about rainforests facing destruction. According to Sassan Saatchi of NASA’s Jet Propulsion Laboratory, “frequent droughts, higher temperature and longer dry seasons, along with increasing pressures from deforestation and degradation in the last two decades, have pushed the tropical rainforests to the verge of a tipping point.”
