As a result of domestic and foreign pollution, 37% of Austria's forests had been damaged by acid rain and/or pollutant emissions by 1991. The damage to forests has had dire consequences, including the decimation of forests that for centuries had protected many Alpine communities from avalanches, erosion, mudslides, or flooding caused by runoff.
