Creator:: Bailey, Arthur Wesley, 1938-
Abstract:: Forest associations, secondary succession, and relationships of plant communities to Roosevelt elk were investigated. Stratification of vegetation into ecological units and an understanding of secondary succession by habitat-type were a necessary first step in investigations into browsing of conifers by elk. The study was jointly conducted by the Oregon State...

Abstract:: A study was initiated in 1961 to characterize seral plant communities in a part of the Cedar Creek drainage in the Tillamook Burn. Stratification of vegetation into ecological units was a necessary first step in conifer-animal damage studies supported by the Oregon State Game Commission. Reconnaissance information was recorded in...

Abstract:: Twelve sites of uniform topography and soils were selected in the Pinus ponderosa/Purshia tridentata/Festuca idahoensis Association. These sites were located in the rain shadow on the east flank of the Oregon Cascades. A fire history in the form of fire scars on ponderosa pine was available for nine of these...

Creator:: Young, James A. (James Albert), 1937-
Abstract:: This investigation was undertaken to characterize and evaluate the forage production and utilization of the successional vegetation of the mixed conifer forest. Field studies were carried out during the summers of 1962 through 1964 at the Eastern Oregon Experiment Station Hall Ranch which is located 12 miles southeast of Union,...

Creator:: Anderson, Howard George
Abstract:: A study was undertaken in the Marys Peak watershed with the following objectives. First, a classification of the major plant communities was carried out. Second, some of the ecological features of Acer circinatum that account for its distribution within these communities were determined. The following plant communities are described: Corylus...

Creator:: Edmonds, Robert L., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: The specific objectives of the program are: (1) To understand the relative behavior of terrestrial and aquatic ecosystems in various environments in the biome. (2) To develop conceptual and computer simulation models that describe nutrient, carbon, and waterflows on a short-term basis (fewer than ten years) and which integrate research...

Creator:: Zavitkovski, J.
Abstract:: The ecological and silvicultural importance of snowbrush, Ceanothus velutinus, in the areas west of the summit of the Oregon Cascades was studied. Particular attention has been given its nitrogen- fixing ability under both field and greenhouse conditions. On west slopes of the Oregon Cascades snowbrush occurs above 2, 500 feet...

Abstract:: Research activities in the post-IBP phase of the Biome program prior to July 1975 were reported in Internal Report 162. Summaries of research and synthesis activities from July 1975 to August 1976 are presented here. The reports are arranged in the following order: Analysis of individual terrestrial ecosystems, which has...
