2018 drought damaged Swiss forests
Last year’s extended heatwave damaged forests in Switzerland.

A study by the Forest, Snow and Landscape Research Institute shows there was leaf discoloration earlier, reduced growth and more trees died.
Andreas Rigling from the institute says the drought in 2018 was extraordinary and the effects on forests is visible.
When compared to hot summers in 2003 and 2015, last year was more severe. The institute says such a drought should only occur once every 100 years.
