Movement of water through forested soils in steep topography

Creator:: Harr, R. Dennis (Robert Dennis), 1941-, Ranken, Darren W., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: 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....

Terrestrial decomposition 1973 : a synopsis

Creator:: Fogel, Robert, Cromack, Kermit, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: 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...

Variation in air and soil temperatures in forest communities on the H. J. Andrews Experimental Forest, 1970-1972

Creator:: Zobel, Donald B., McKee, Arthur, Hawk, Glenn M., Dyrness, C. T., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Air temperatures at i m and soil temperatures at 2C cm are reported for twenty-one forest stands in the central Western Cascader of Oregon. Records began in 1970 for some stands, in 1971 or 1972 for most. Temperature Growth Index for a stand, based on temperature effects on Douglas-fir seedling...

Identification and characterization of forest communities and habitat types in and adjacent to the H. J. Andrews Experimental Forest

Creator:: Dyrness, C. T., Franklin, Jerry F., Zobel, Donald B., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: 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...

Acari, insecta and nematoda of watershed 10, H. J. Andrews experimental forest

Creator:: Krantz, G. W., Wernz, J. G., Jensen, Harold J. (Harold James), 1921-, Shimabukaro, R., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Populations of mites and.nematodes were monitored on Watershed 10, H. J. Andrews Forest. A minimum of 50 families and 60 genera of mites are present, the majority being Cryptostgmata. Population estimates vary from 5000-350,000 per square meter. Nine categories of nematodes are present, most belonging to the saprozoic, dorylaimoid, aquatic...

Vegetation and soils of watersheds 2 and 3, H. J. Andrews Experimental Forest

Creator:: Hawk, Glenn M., Dyrness, C. T., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Early in the planning of the Coniferous Biome program It was recognized that experimental watersheds 2 and 3 in the H. J. Andrews Experimental Forest might provide ideal study sites for certain phases of the Biome program. A study was funded during year 1 (1970) to provide necessary background ecological...

Recent geomorphic history in the area of experimental watersheds 1, 2, 3, 9, and 10, H. J. Andrews Forest

Creator:: Swanson, Frederick J. (Frederick John), 1943-, James, Michael E., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Studies in the lower Lookout Creek-Blue River area have revealed a geomorphic history including glaciation and the development of three alluvial surfaces, presently active alluvial cones and older, deeply dissected cone remnants. Results are based on landform mapping, analysis of the types and distributions of surficial sediments, and the distribution...

Abstract:: This report lists 98 microfungi found in the H. J. Andrews Experimental Forest, Lane County, Oregon, between June 1970 and August 1972. The taxonomic treatments of the Ascomycetes and the Fungi Imperfecti in general follow Dennis (1968) and Barnett (1960), respectively. Specimens are deposited in the herbarium at Oregon State...
