The health of the northern hardwood forest in the Southern Appalachian Mountains of Tennessee, North Carolina, and Virginia has recently gained attention from the media and environmental stakeholders. This project was designed to examine concentrations of metals, including lead, aluminum, and calcium in growth rings of an important northern hardwood species, American beech (Fagus grandifolia Ehrh.) at Mount Rogers and Whitetop Mountain, Virginia. Dominant and codominant trees were sampled from sixteen research plots located at two different elevations. Samples were crossdated, divided into sections of ten-year periods, and analyzed using atomic absorption spectroscopy. Concentrations of metals were negatively correlated …
