Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: In an effort to describe the plant communities and succession of the Oregon coastal grasslands, vegetation and environmental data were collected from 75 stands at 24 separate locations ranging from Cape Falcon in Tillamook County to Cape Ferrelo in Curry County. The vegetation data consisted of cover and frequency values...

Ecology of riparian plant communities in southern Malheur National Forest

Creator:: Padgett, Wayne G.
Abstract:: Riparian communities in the southern portion of Malheur National Forest were intensively studied with the objective of designing an approach for classifying disturbed riparian areas into units of similar potential. Not all riparian community types in this portion of the Blue Mountains were sampled due to time limitations. Some of...

The effects of the Mazama tephra-falls : a geoarchaeological approach

Creator:: Matz, Stephan E.
Abstract:: About 7,000 years ago two major tephra-falls blanketed the Pacific Northwest in volcanic ash. These two tephra-falls, identified as the Llao and climatic tephra-falls, were a part of the eruptive events that led up to the collapse of Mount Mazama to form Crater Lake in the southern Oregon Cascades. The...

Fire ecology and management in plant communities of Malheur National Wildlife Refuge, southeastern Oregon

Creator:: Young, Richard P.
Abstract:: This research assesses prescribed burning as a habitat management technique in wetlands and associated upland communities of Malheur National Wildlife Refuge, southeastern Oregon. Experimental burns were conducted to evaluate fire behavior and effects in wetland and upland habitats, and, fire effects on Cirsium arvense. Wetland plant communities were monotypic stands...

Willamette and associated soils on late Pleistocene geomorphic surfaces, Polk County, Oregon

Creator:: Gelderman, Frederick W.
Abstract:: The morphology and genesis of soils of the Willamette series and of some Willamette-associated soils and their relationships to geomorphic surfaces were studied in an area near McCoy, Polk County, Oregon. Influences of regional extent, such as climate and parent material, were related to the soils and landforms. The soils...

Stratigraphy and genesis of soils from volcanic ash in the Blue Mountains of Eastern Oregon

Creator:: Rai, Dhanpat, 1943-
Abstract:: Investigations were conducted to (1) determine the original pattern of deposition and thickness of ash in the Ochoco and Blue Mountain areas of Oregon, (2) determine if discontinuities exist in the parent material of these soils, (3) determine the degree of mixing of ash with other materials and evaluate reworking...

Comparative study of some soil characteristics of grassland and forest/grassland transition in western Oregon

Creator:: Ezenwa, Matthew Ikechuku Sunday
Abstract:: Vegetation as a soil-forming factor was studied under forest transition and grass while attempting to keep other soil forming factors constant in the western part of the Willamette Valley, Oregon. The physiographic units consist chiefly of the interior foothills and slopes formed from an old basaltic flow with some interspersed...

Mineralogical and chemical characteristics of western Oregon Andic soils

Creator:: Franklin, William Talbert
Abstract:: A study was conducted to determine the mineralogy and chemical properties of "Ando-like" western Oregon soils. The samples were collected from 13 sites which formed mainly from basaltic rocks, a contact metamorphic rock, sedimentary rocks, and alluvium derived from sedimentary rock and from volcanic rock. All samples contained small amounts...
