Abstract
⺠SO2 pollution caused the decline of exposed mountain spruce forests in Europe. ⺠Soil acidification versus foliar damage were discussed as alternative mechanisms. ⺠Exposure to high SO2 levels reduced tree-ring width in Norway spruce. ⺠Recently, clean air acts caused a rapid decrease of SO2 pollution. ⺠Rapid recovery of stem growth suggests a key role of foliar damage in spruce decline.
