Livestock, deer and logging interactions in the lodgepole pine/pumice region of central Oregon

Creator:: Stuth, Jerry W.
Abstract:: The objectives of this study were to: 1) determine production of plant species and utilization by cattle, sheep and deer as related to plant communities and timber management practices and 2) evaluate the interaction of range use between cattle and deer and between sheep and deer as affected by site...

Limits on aboveground net primary production, leaf area, and biomass in vegetational zones of the Pacific Northwest

Creator:: Gholz, Henry L.
Abstract:: Samples of mature vegetation from 8 of 12 major vegetational zones in Oregon and Washington, representing about 80% of the area of the two states, were studied along a latitudinal transect from the Pacific Coast to the east slopes of the Cascade Mountains. Six stands were in forest zones, one...

The suspended sediment regimes of two small streams in Oregon's Coast Range

Creator:: Paustian, Steven Julius
Abstract:: The protection of water quality and the maintenance of productive anadromous fisheries is a primary concern in the Pacific Northwest. Excessive suspended sediment loads is a principle water quality problem on small wildland watersheds in this region (Anderson, 1971; Brown, 1972). Man's activities have been shown to increase sedimentation rates...

Man and the land : an ecological history of fire and grazing on eastern Oregon rangelands

Creator:: Shinn, Dean Allison
Abstract:: Ecological and historical information are combined in examining the environmental influence of fire and grazing on rangelands in eastern Oregon through time. Competitive relationships between herbaceous and woody flora in the northern Great Basin are discussed, focusing broadly on the shrubsteppe regions 'of Franklin and Dyrness (1973) but with special...

A chorological analysis of the grass balds in the Oregon Coast Range

Creator:: Aldrich, Frank T.
Abstract:: Detailed phytosociological and physical data were gathered from six grass-fern balds in the Oregon Coast Range, Monmouth Peak, Grass Mountain, Prairie Peak, Roman Nose Mountain, Tyee Mountain, and Saddle Mountain. Panchromatic and color infrared air photography guided sampling within individual balds. The resultant floristic data was manipulated by a Braun-Blanquet...

Forest vegetation and soils of terraces and floodplains along the McKenzie River, Oregon

Creator:: Hawk, Glenn M.
Abstract:: A study of the McKenzie River floodplains, terraces and glacial outwash plains was undertaken to classify and describe the vegetation and soils of a previously little studied synecological unit. During the summer of 1971, 54 analytic vegetation and soil plots (stands) were studied. Cover and frequency of all trees, shrubs,...

Effects of bark debris on benthic macro-fauna of Yaquina Bay, Oregon

Creator:: Walker, John David
Abstract:: Benthic samples were collected during the summer, winter and spring seasons from upper Yaquina Estuary, a region used by Georgia- Pacific Corporation for log dumping and storage. Samples came from an active log dump and storage areas as well as areas not associated with log handling activity. The samples were...

Vegetative ecology of Hunts Cove, Mt. Jefferson, Oregon

Creator:: Campbell, Alcetta Gilbert
Abstract:: The vegetative communities in the subalpine meadows of Hunts Cove, Mt. Jefferson, and some of the major environmental factors affecting them were studied in the summer of 1971. Hunts Cove is in the subalpine Tsuga mertensiana parkland of the Central Oregon High Cascades. Habitats within the Cove vary considerably; elevation...

Nitrogen, phosphorus and particulate matter budgets of five coniferous forest ecosystems in the western Cascades Range, Oregon.

Creator:: Fredriksen, R. L.
Abstract:: Nutrient and particulate matter balances were established for five ecosystems dominated by Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] in the western Cascades, Oregon. Carriers of N and P were particulate matter (dust in precipitation and sediment in streams) and dissolved matter in both precipitation and stream water. The input and outflow...
