Climate impacting on trees—1 December 2015

Climate change and extreme climatic events appear to be killing trees around the world. ARC Discovery Early Career Researcher Awardee, Dr Melanie Zeppel, from Macquarie University suggests these changes in climate are also reducing tree growth and health. “After heat waves and extreme drought, 25% of mature trees died in 2010–2011 across 7000 hectares of Western Australian forest,” said Dr Zeppel. “Changing climates will dramatically affect our woodlands and forests, often with complete changes of forest communities…Dying forests also provide more fuel for bushfires, which are coming earlier in the year, with dramatic impacts on both humans and animals.”
