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

Soils synoptic sampling grid (REU sites) site locations at the Andrews Experimental Forest are mapped. GPS coordinates were used to generate sample locations from a synoptic soil sampling performed by students as part the Research Experience for Undergraduates(REU) program. To document the geographic locations of study sites. Processing Procedures - SP028

Purpose: To document the geographic locations of study sites.

Methods

Method Steps

Processing Procedures - SP028
  • SP02801: GPS coordinates were used to generate sample locations from a synoptic soil sampling performed by students as part the Research Experience for Undergraduates program . Data was converted into UTM. Projection for Nad27 was corrected 01/09/1998. Data was checked by Bob Griffiths via a hardcopy map of Digital Orthophotography and individual points were moved as directed by Bob (in 2002). In the initial 1993 study, 130 sites were sampled which were located at 0.5 km intervals along most of the main roads. In 1994, the sampling grid was expanded to 183 sites providing a more comprehensive sampling grid. Because of potential edge effects problems, all sample locations were moved at least 20 meters from the closest road or clearing. Changes from the original location are given in Table 1. While conducting autocorrelation analyses, we found that for the variables studied, samples collected at 5 m intervals were not autocorrelated and could thus be considered independent for statistical analysis. For this reason, replicate samples were taken in plots separated by 5 meters along a transect parallel to the road. Data in geographic projection.

Instrumentation:

  • GPS: locations should be good within 5 meters
