Description:The site is located on land designated as a Research Natural Area (RNA). The site is very open, with even-aged stands of old-growth trees, young trees and mixed aged stands. The eddy-flux tower footprint was classified as ~ 48% mixed aged, ~27% pure old growth and ~25% young aged stands. The data in this workbook describes the mixed aged component. A separate workbook describes the pure old growth component.
