Abstract: 

LIDET is the LTER Longterm Intersite Decomposition Experiment Team. It is a leaf, wood, and root decomposition study carried out at 28 LTER and other sites including LUQ. The duration of the study is designed to be approximately 10 yrs at temperate zone sites and approximately 3 yrs at tropical zone sites because of higher decomposition rates there. The same decomposing materials, litter bags, and study design are used at all sites to facilitate intersite comparisons. Not all species were used at all sites. Six leaf litter species were used extensively at all sites that cover a range of leaf quality to permit a comparison of effects of litter quality and climate on decomposition. The others were present in the study as "wild cards", with at least one species contributed by each site. Three species of roots, and one species of wood were used.

Methodology

Methods: 

Leaves were placed in mesh bags with 0.1 mm lower holes and either 1 or 7 mm upper holes. Roots were all in 0.1 mm mesh bags. Leaves and root bags were placed under the soil surface litter layer. Wood was commercial 1/4 inch dowels inserted halfway into the ground to measure both aboveground and belowground decomposition rates. All materials were placed in the field at the same time. At each sampling period, 4 replicates of each assigned type were collected and sent to Oregon State University for processing. At LUQ, litter was field exposed at 350 m elevation in Tabonuco forest type near the El Verde Field Station.
