Yellow Birch in the Southern Appalachians

Client: USDA-Forest Service: Southern Research Station

A four-year collaborative effort between Equinox and the Southern Research Station, the Yellow Birch project aims to determine the effects of acid deposition on stands of yellow birch at high elevations. Years 1 and 2 involved establishing and collecting tree and mineral soil data within 48 plots across the high mountains. In year 3, the three largest yellow birch and associated tree species in each plot were cored for chemoanalysis and intentionally damaged in order to monitor wound response. In year 4, smaller-diameter birch and associated trees were cored to evaluate effects of acid deposition in younger trees.
