Description

A survey of red spruce growth trends at several sites in the Great Smoky Mountains National Park (GSMNP) was undertaken to determine the relationship of the magnitude and timing of changes in annual radial increment to elevation, aspect, tree age, mortality, and competitive status. The growth changes observed suggest responses to changes in climate (principally temperature) or atmospheric pollution acting individually or, more likely, in combination. Major emphasis on these potential causes is warranted in future studies. 56 refs., 8 figs., 11 tabs.
