Title: Forest floor Carbon & Nitrogen pools at the Coweeta LTER Terrestrial Gradient Sites, Coweeta Hydrological Laboratory, Otto, NC.
Abstract: This project is part of a larger examination of site productivity along an elevational gradient. Forest floor weights, %C, and %N were measured at each of the five terrestrial gradient plots located along an elevational gradient at Coweeta Hydrologic Lab, Otto, NC.
