  Citation × Citation Citation Abstract Copy Title: Identification and characterization of forest communities and habitat types in and adjacent to the H. J. Andrews Experimental Forest Author: Zobel, Donald B., U.S. International Biological Program. Coniferous Forest Biome, Dyrness, C. T., University of Washington, Franklin, Jerry F. A total of 23 forest communities have been identified and characterized in a preliminary manner. Data used in formulating the classification had previously been collected on 300 reconnaissance plots located on the H. J. Andrews Forest and surrounding area. Vegetation classification was facilitated by similarity analysis and stand ordination procedures developed by Dr. Will Moir, formerly of Colorado State University. Results of stand ordination indicate the presence of strong moisture and temperature gradients along which forest stands array themselves.

Dennis (Robert Dennis), 1941-, Ranken, Darren W., University of Washington Field and laboratory studies are being conducted to describe the hydrologic properties of soil and to determine the timing pathway of precipitation and snowmelt water as it moved through forested soil on a steep slope. Hydrologic properties include hydraulic conductivity, porosity, pore-size distribution, moisture characteristics, stone content, and soil depth. Laboratory analyses indicated an abrupt change in hydrologic properties within the top 1.5 m of soil. Water input and movement through the soil are being monitored during winter storm events.

• 4. [Article] Terrestrial decomposition 1973 : a synopsis

  This report describes decomposition studies conducted in the H. J. Andrews Forest, Oregon in 1973. Changes in weight loss and nutrient content of leaves, cones, branches, and bark of Douglas-fir and leaves ...

  Citation × Citation Citation Abstract Copy Title: Terrestrial decomposition 1973 : a synopsis Author: U.S. International Biological Program. Coniferous Forest Biome, Cromack, Kermit, Fogel, Robert, University of Washington This report describes decomposition studies conducted in the H. J. Andrews Forest, Oregon in 1973. Changes in weight loss and nutrient content of leaves, cones, branches, and bark of Douglas-fir and leaves of big-leaf maple, vine maple, Rhododendron, red alder, sword fern Oregon oak, and Chinkapin were recorded in a variety of habitats ranging from wet, to dry. Weight loss is related to the moisture content of the forest floor and percent lignin content of the material. Decomposition is slowed in the dry summer months, and there are differences in weight loss of substrates between habitat types.
