Abstract

Although many studies have identified the characteristics of wood stored in streams, few have attempted to measure the long-term dynamics of large wood. From 1982-1985, we developed a long-term study of input, storage, decomposition, and redistribution of large wood in Mack Creek. Each year from 1985 to the present, we have surveyed a 1.1 km section of this stream. This annual survey has allowed us to quantify the standing stocks and characteristics of large wood within the stream and floodplain of an old-growth forest and an older (ca. 1963) clear-cut. In addition, these data allow us to measure rates of input, fragmentation and movement.

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.

This annual survey has allowed us to quantify the standing stocks and characteristics of large wood within the stream and floodplain of an old-growth forest and an older (ca. 1963) clear-cut. In addition, these data allow us to measure rates of input, fragmentation and movement. To provide a long-term record of large wood pieces in both an undisturbed and a modified stream channel.

Purpose: To provide a long-term record of large wood pieces in both an undisturbed and a modified stream channel. Most work on in-stream wood uses a "snapshot" approach, and does not provide any temporal information. This study was designed to monitor in-stream wood over a long time scale.

Methods

Method Steps

Field Methods - GS006
  • Each piece of wood greater than 10 cm in diameter and 1 m in length is tagged in 6 locations. Holes are drilled through the bark in each "corner" of the log and round numbered tags, with letters A, B, C, or D, are nailed into each recess. Two surface tags, one metal and the other plastic, are nailed (four nails per tag) on opposite sides of the log. Tag colors may be orange, blue or white. During the annual autumn resurvey, investigators search for all logs within the study section. The status of each piece is recorded; if the log is in the same reach, location and position as the previous year, other attributes are presumed to also be unchanged. Logs which have moved within the study grid have all attributes recorded. New input (from windthrow, snowthrow, or other mechanisms) are tagged (see above) and all attribute information recorded.

Sampling

Study Extent
  • Mid-elevation, third-order stream. Gradient of 8%- 15%. Lower 350 m is in portion clearcut in 1963, with stream gage and flume at the top of the reach. Upper 750 m is in 500 year-old old-growth stand dominated by Tsuga heterophylla (TSHE), Psuedotsuga menziesii (PSME), and Thuja plicata (THPL). Study area consists of stream channel plus adjacent floodplain, and encompasses a riparian reference stand (TV010), monumented channel cross- sections (GS002), stream discharge (HF004), water chemistry (CF002), and meteorology (MS001).
  • Sampling frequency: Annual
Sampling Description
  • The study population consists of all pieces of wood in the stream channel and floodplain in the1.1 km study section. Only logs greater than 10 cm in diameter and 1 m in length are tagged initially (breakage may result in smaller pieces). Each piece of wood is receives 6 colored and numbered tags, and the following attributes described: location within the survey grid, longitudinal position, geomorphic location, log dimension, decay class, moss cover, origin, rood wad, channel angle, proportion of volume in wetted channel, active channel, and floodplain. The entire reach is re-inventoried annually in October. New or moved pieces are tagged and complete descriptions recorded.
