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.

Study Description

To examine soil respiration as influenced by temperature and moisture to determine the role of CO2 evolution rates in overall carbon dynamics. Field Methods - SP005

Methods

Method Steps

Field Methods - SP005
  • On July 14-15, 1993, CO evolution rates were measured using soda lime jars in the same chamber that have been used for the gas-flux experiments. Sites were located approximately 0.5 km apart along HJA roads. Locations were fixed by their location relative to road intersections and clearcuts. Approximately every 10 sites, we put out a control to compensate for background CO concentrations and CO adsorbed during the drying process.
Laboratory Methods - SP005
  • Predried and weighed jars were used in this experiment. After the jars were exposed to the atmosphere, they were dried and weighed at the HJA. The control jars were taken at approximately the same elevation and in the same vegetation type as the actual samples whenever possible. Soil and air temperatures were recorded when the jars were placed out and when they were retrieved (usually 24 hours later). Max-min thermometers were placed at each site where the controls were run, and recorded 24-hour max and min air temperatures. Soil cores were taken to a depth of 10 cm and dried at 100°C for 12 hours. The major vegetation at each site was also noted and a desription of those sites are also listed in the site description dataset. The positions of the sites were estimated by tracing distances along roads using a map generated by Hazel Hammond and the discriptive logs were made in the field.
  • Soil respiration values have been corrected for background CO and CO adsorbed in the drying process using the mean of the control weight differences for each of the two transects.
