Abstract

This study is part of the long-term log decay study (200 years). The experiments are being conducted at six sites located within intact old-growth Douglas-fir-western hemlock forests. This study tests the effect of log species and decomposition on the release of nutrients and carbon via leaching. This experiment is designed to investigate flow pathway through these logs; that is, throughfall, run-off from the top, and leachate from the bottom. Water collectors were installed on each log to collect the sample to be analyzed for various nitrogen and carbon content.

Abstract
  • The H.J. 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.

Study Area Description
  • Long-Term Ecological Research
    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.

Sampling Description
  • The experiments are being conducted at six sites located within intact old-growth Douglas-fir-western hemlock forests. The experimental design is a split-split plot in time. Each site represents a block, and log species is the the main plot effect. Flow pathway that is, throughfall, run-off from the top, and leachate from the bottom is the subplot effect.
