Abstract

A network of more than 130 permanent vegetation plots provides long-term information on patterns and rates of forest succession in most of the major forest zones of the Pacific Northwest. The plot network extends from the coast to the Cascades in western Oregon and Washington and east to ponderosa pine forests in the Oregon Cascades. Most of the permanent plots were established during two intervals: from 1910 to 1948, and from 1970 to 1989. The earlier plots were established by U.S. Forest Service researchers to quantify timber growth in young stands of important commercial species and to help answer other applied forestry questions. The more recent period of plot establishment began under the Coniferous Forest Biome program of the International Biological Program during the 1970s, and continued under the Long-term Ecological Research program. A broader set of objectives motivated plot establishment since 1970, especially quantification of composition, structure, and population and ecosystem dynamics of natural forests. Plots have one of three spatial arrangements: (1) contiguous rectangles subjectively placed within an area of homogeneous forest; (2) circular plots subjectively placed within an area of homogeneous forest; and (3) circular plots systematically located on long transects to sample an entire watershed, ridge, or reserve. Rectangular study areas are mostly 1.0 ha or 0.4 ha (1.0 ac) in size (slope-corrected). Circular plots are 0.1 ha (0.247 ac), not corrected for slope. The tree stratum is the focus of work in closed-forest study areas. All trees larger than a minimum diameter (5 cm for most areas) are permanently tagged. Plots are censused every 5 or 6 years. Attributes measured or assessed at each census include tree diameter, tree vigor, and the condition of the crown and stem. The same attributes are recorded for trees (ingrowth) that have exceeded the minimum diameter since the previous census. In many plots tree locations are surveyed to provide a plot-specific x-y location. A mortality assessment is done for trees that have died since the previous census. The assessment characterizes rooting, stem, and crown condition, obvious signs of distress or disturbance, and the apparent predisposing and proximate causes of tree death.

Purpose

The study purpose is to examine long-term trends and dynamics of representative forest types in the Pacific Northwest. The study provides baseline information on long-term rates of tree growth and tree regeneration (ingrowth), causes and characteristics of tree mortality, forest productivity and biomass, and spatial patterns (demography) of ingrowth and mortality. Long-term observations are the only direct means to document and understand the slow changes of our forests which are dominated by long-lived trees species (individuals commonly live 400 to 1000 years). Long-term observations can quantify levels and dynamics of natural forest structures to be used as guides in ecosystem management. Long-term observations provide the definitive measure of long-term productivity and, thus, sustainable harvest levels. Long-term observations also provide a basis for monitoring effects of global climatic change as well as other changes.

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.

Methods

Method Steps

Field Methods - TV010

The stands are surveyed into 25 X 25 slope corrected subplots marked with permanent stakes. All trees greater than the minimum size (usually 5 cm dbh) are tagged, diametered, vigor coded, and mapped. The mapping is done using a 5 X 5 m grid formed with string as a guide. See attached sheet for details.

Sampling

Study Extent

Sampling frequency: 1-6 years

Sampling Description

The sites were selected subjectively to represent modal examples of the major habitat types in the H.J. Andrews area (usually with a mature and old growth example). Some stands (e.g.riparian) were selected for other reasons. The stands are remeasured at 5 to 10 year intervals to provide growth and regeneration information.
