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. inventories detritus inorganic nutrients woody debris organic matter LTER controlled vocabulary fine woody debris Andrews Experimental Forest site thesaurus inorganic nutrients organic matter LTER core research areas Harmon, Mark E.; Sexton, Jay. 1996.

Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics. Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition. The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources. Data were provided by the HJ Andrews Experimental Forest research program, funded by the National Science Foundation's Long-Term Ecological Research Program (DEB 2025755), US Forest Service Pacific Northwest Research Station, and Oregon State University. National Science Foundation: DEB1440409 The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms. 1 TD02401 Fine Woody Detritus Line Transect Data, Volumes, and Masses: TD02401.csv 40970
