Dieback

One of the causes of forest dieback is acid rain.

The whole world is talking about forest dieback.

Even under future scenarios in which atmospheric greenhouse gases rise dramatically, the models project the dry season in the southern Amazon to be only a few to ten days longer by the end of the century and therefore the risk of climate change-induced rainforest dieback should be relatively low.

The National Trust reports that 30,000 ash trees on its land will have been felled this year owing to ash dieback. “Dieback” sounds like a gentle, seasonal withdrawal. In fact, ash dieback is a devastating disease caused by a fungus, Hymenoscyphus fraxineus, likely to have been carried into the UK on imported ash saplings in the early part of this century.
