Morphometric properties of nivation hollows on Hart Mountain, Lake County, Oregon

Creator:: Rademacher, Christopher L.
Abstract:: Hart Mountain is a basaltic fault block mountain in the semi-desert region of the northern Basin and Range province in south-central Oregon. Geomorphic processes associated with lingering snowpatches have formed nivation hollows, which are small scale depressions in the hillsides. The lingering snow in the hollows prohibits shrub growth. Bedrock...

Vegetation ecology of selected mountain hemlock (Tsuga mertensiana ) communities along the eastern High Cascades, Oregon

Creator:: Schuller, S. Reid
Abstract:: Tree diameter, understory plant cover, seedling density, elevation, aspect, and slope steepness are recorded for 51 forest stands dominated by Tsuga mertensiana (Bong.) Carr. along the eastern portion of the central Oregon Cascades. Species dominance based on prominence values for trees and percent cover for shrubs and herbs are correlated...

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...

Some ordinations of forest vegetation of the Western Siskiyou Mountains, Oregon

Creator:: Plemons, Carolyn LaVona
Abstract:: The western Siskiyou Mountain forest vegetation is grouped into eight communities based on parent material. Three groups of data are analyzed using a computerized ordination technique, two of the groups together, and one separately. Two communities associated with ultramafic parent materials, two on sandstone, one on greenstone, and one on...

The cultural significance of mountain regions : implications for the Calapooya Divide, Oregon

Creator:: Starr, Karen J.
Abstract:: Altitudinal variations in upland regions of the earth create variable climatic zones and conditions. Plant and animal communities must adapt to these conditions, and when they reach their tolerance limits for environmental conditions at the upper levels of a zone, they cease to exist in the environment. Humans also utilize...

Assessing cohesion and conflict behavior in an Oregon mountain community

Creator:: Jones, Gregory Jeffery
Abstract:: The objectives of this paper are (1) to apply certain techniques for evaluation of social impacts in a small community situation, and (2) to determine whether or not the selected techniques are useful for measuring the impact on community cohesion of a rapid increase in single family housing in a...

Lahar hazard mapping of Mount Shasta, California : a GIS-based delineation of potential inundation zones in Mud and Whitney Creek basins

Creator:: McClung, Steven C.
Abstract:: Mount Shasta, the southernmost stratovolcano in the Cascade Range (41.4°N) has frequently produced lahars of various magnitudes during the last 10,000 yr. These include large flows of eruptive origin, reaching more than 40km from the summit, and studies have shown that at least 70 debris flows of noneruptive origin have...

"Training site" selection for computer analysis of snowfield extent; southern Cascade Mountains, Oregon

Creator:: Parker, David Bill
Abstract:: Data from the southern Cascade Mountains of Oregon has been collected for application in computer analysis of snowfields. Vegetation type, canopy cover, slope, aspect, insolation, and snowfield ground truth delineation are given consideration. In addition, a procedure for transferral of data onto Landsat imagery was derived.
