Title
Fine woody detritus volume and mass in small watersheds at Andrews Experimental Forest, 2002 to 2003
Abstract
Four small watersheds (WS06, WS07, WS08, and WS09) at the Andrews Experimental Forest were inventoried for fine woody detritus (FWD) using the line transect method as described in Guidelines for measurements of woody detritus in forest ecosystems (Harmon and Sexton 1996). In each watershed plot, four transects of 4 meters in length were inventoried. Slopes of the transect were determined as the plots were not laid out slope corrected. The number of pieces of FWD were tallied along each transect for two size classes, 0.63-2.54 cm and 2.54-7.62 cm. Volume calculations were determined by use of the formula in Harmon and Sexton 1996. Mean bulk density was determined from samples collected and measured. Field measurements used to determine density included diameter and length. In the lab, the samples were weighed to determine wet weight and dried.
