'It's heart-wrenching': 80% of Blue Mountains and 50% of Gondwana rainforests burn in bushfires

Guardian Australia analysis reveals the frightening amount of world heritage area burned in Australia's ongoing fire crisis

At least 80% of the Blue Mountains world heritage area and more than 50% of the Gondwana world heritage rainforests have burned in Australia's ongoing bushfire crisis.

The scale of the disaster is such that it could affect the diversity of eucalypts for which the Blue Mountains world heritage area is recognised, said John Merson, the executive director of the Blue Mountains World Heritage Institute.
