Litter Decomposition Studies

Long-term Intersite Decomposition Experiment Team (LIDET)

The LIDET experiment is designed to test the effects of substrate quality and macroclimate on long-term decomposition and nutrient release dynamics of fine litter. The experiments have been istalled at 28 sites that span a wide array of ecosystems, from tundra to warm desert to shortgrass steppe to moist tropical forest. The ARC LTER site is one of those sites participation in this experiments. Mark Harmon at the Department of Forest Science, Oregon State University, Corvallis, OR, e-mail harmonm@ccmail.orst.edu, is lead PI. .

  • 1990_2000ArcLIDETMass - This file is from the Long-term Carbon and Nitrogen, and Phosphorus Dynamics of Leaf and Fine Root Litter project (LIDET-Long-term Intersite Decomposition Experiment Team). This file contains only the Arctic LTER data. In particular the mass looses over the ten year study. Three types of fine roots (graminoid, hardwood, and conifer), six types of leaf litter (which ranged in lignin/nitrogen ratio from 5 to 75), and wooden dowels were used for litter incubations over a ten year period.
