Indirect effects and the Long-term Risks of Air Pollution on Tolerant Hardwood Forest Ecosystems in Central Canada
1993
Morrison, I.K. (Forestry Canada Ontario Region, Sault Ste. Marie (Canada))
There is a strong evidence to indicate that sulphates and nitrogen oxides cause increased leaching of base cations, principally calcium and magnesium from soils supporting old-growth sugar maple forest in central Canada. Sugar maple trees sequester Ca, especially in bark. A site low in exchangeable bases might become less productive, if subjected to prolonged high rates of leaching and full tree harvesting.
