Abstract

Weekly maximum and minimum water temperatures were recorded at the gaging stations on three small watershed (Watersheds 1, 2, and 3) in the Andrews Experimental Forest from 1959 through 1966. The period from 1959 to 1962 represents before-logging conditions. Watershed 2, which remained undisturbed through this period, served as a control in statistical comparisons. Temperatures continued to be recorded from these watershed until 1981. From 1964 to 1980, temperatures were recorded at watersheds 6, 7, and 8. Watershed 10 temperatures were recorded from 1981 through 1983.

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.

Purpose: To determine water temperature changes that occur when old-growth Douglas-fir forests are logged.

Methods

Method Steps

Field Methods - HT001
  • Water temperature was measured with "U" tube maximum-minimum thermometers, submerged in the stream near the gaging station on each watershed. The thermometers were checked with standard mercury thermeter at the time of each weekly reading. Linear regressions based on weekly maximum and minimum water temperatures were calculated to express the relationship of the watershed during periods representing a range in cover conditions.
Laboratory Methods - HT001
  • Minimum and maximum temperatures were read from strip charts.

Sampling

Study Extent
  • Gauging stations on small watershed (Watersheds 1, 2, 3, 6, 7, 8, 10) in the Andrews Experimental Forest
  • Sampling frequency: periodic and daily
