  • An American tragedy: why are millions of trees dying across the country?


    A quiet crisis playing out in US forests as huge numbers of trees succumb to drought, disease, insects and wildfire – much of it driven by climate change

    sept 19,2016


    JB Friday hacked at a rain-sodden tree with a small axe, splitting open a part of the trunk. The wood was riven with dark stripes, signs of a mysterious disease that has ravaged the US’s only rainforests – and just one of the plagues that are devastating American forests across the west.

    Friday, a forest ecologist at the University of Hawaii, started getting calls from concerned landowners in Puna, which is on the eastern tip of Hawaii’s big island, in 2010. Their seemingly ubiquitous ohi’a trees were dying at an astonishing rate. The leaves would turn yellow, then brown, over just a few weeks – a startling change for an evergreen tree.

    “It was like popcorn – pop, pop, pop, pop, one tree after another,” Friday said. “At first people were shocked, now they are resigned.
    “It’s heartbreaking. This is the biggest threat to our native forests that any of us have seen. If this spreads across the whole island, it could collapse the whole native ecosystem.”

    But the plight of the ohi’a is not unique - it’s part of a quiet crisis playing out in forests across America. Drought, disease, insects and wildfire are chewing up tens of millions of trees at an incredible pace, much of it driven by climate change.
