Title: Gradient throughfall (thrufall) collection at the Coweeta Hydrologic Laboratory from 1992 to 1997
Abstract: To investigate long term forest ecosystem responses to disturbance and stress along an elevational gradient, five plots were established as follows: xeric oak-pine (782 m), cove hardwood (795 m), low elevation mixed oak (865 m), high elevation mixed oak (1001 m), and northern hardwoods (1347 m). Phenomena being studied in these plots include: climatology, nutrient dynamics, decomposition, vegetation productivity and population dynamics, and below-ground processes. As part of study on nutrient dynamics, throughfall was sampled weekly and concentrations and fluxes were examined from each of the five gradient plots.
