Correlation Analysis of Tree Growth, Climate, and Acid Deposition in the LakeStates

摘要

The report describes research designed to detect subtle regional tree growthtrends related to sulfate (SO4) deposition in the Lake States. Correlation methods were used to analyze climatic and SO4 deposition. Effects of SO4 deposition are greater on climatically stressed trees, especially pine species on dry sites, than on unstressed trees. Jack pine growth shows the strongest correlation to both climate and acid deposition.
