KEYWORDS:

Inorganic nutrients, Organic matter, Long-Term Ecological Research (LTER), reference stands, inventories, decomposition, inorganic nutrients, woody debris, organic matter

METHODS:

Experimental Design - TD030:

Description:

Stands were chosen to represent a forest type and successional stage. Vegetation transects were already established for the Early Succession Synthesis Area (TV52) and Wind River NPE (TP107) studies, and these were used to locate FWD quads. Transects were used in the reference stands.

Field Methods - TD030 :

Description:

Fine woody debris is defined as any woody debris greater than 1 cm diameter but less than 10 cm diameter. Quadrats of 1x1 meter were established using a frame. The number of quadrats per stand varied from 5-20. All FWD within the quadrat was collected and weighed (total wet weight). A representative subsample of the total was weighed, oven dried at 55C , and a moisture correction factor was derived. This correction factor was used to adjust the total wet weight to a total dry weight.
