Vegetation ecology of Fraxinus latifolia communities in William L. Finley National Wildlife Refuge, Oregon

Creator:: Heinitz, Eric Fajen
Abstract:: Composition and structure of Oregon ash (Fraxinus latifolia) woodlands in the William L. Finley National Wildlife Refuge, Oregon are described. Twenty stands dominated by Fraxinus latifolia were sampled with 500 m2 circular macroplots in which floristic microplot data were collected for plant community synthesis. Plant communities were identified by computer-assisted...

A georeferenced digital image analysis of micro-topographic patterns within the Willamette Floodplain Research Natural Area, W. L. Finley National Wildlife Refuge

Creator:: Anderson, Karen L.
Abstract:: The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...

An investigation into modeling snow cover elements at Crater Lake National Park and surrounding environs as an improved "ground truth" method for satellite snow observations

Creator:: Hamilton, William L.
Abstract:: Streamflow forecasts are essential to the optimal operation of hydroelectric and irrigation reservoirs in the Pacific Northwest. Satellite snow cover observations would aid in these streamflow forecasts by providing snow cover data at regular time intervals. Unfortunately, satellite capability to remotely sense mountain snow cover conditions is indeterminate due to...

Weather as an influencing factor in the use of Oregon's coastal recreation areas

Creator:: Rense, William Childs, 1944-
Abstract:: The role of weather in influencing tourist-recreation visitation to the Oregon coast during the six-month summer season of May through October has been investigated by this research. In addition, the normal day-to-day fluctuations in coastal visitation has been determined. Based upon the normal visitation, the tourist-recreation season on Oregon's coast...

Urbanization of upper Oak Creek Basin Corvallis, Oregon

Creator:: Williams, James C.
Abstract:: The annual growth rate for the Corvallis-Benton County area has traditionally been higher than the growth rate for the State of Oregon. Corvallis is considered to be one of the most densely settled communities in the state. Since 1972, Corvallis has experienced a drastic decline in the number of housing...

Oregon's early peoples and their relation to the environment : an interpretive approach

Creator:: Possiel, William John
Abstract:: The dramatic upsurge of contract-supported archaeological activity, generated by legislative action, has precipitated an increase in information about Oregon's prehistoric peoples. This information, however, has not been presented in a format which can be easily understood by the general public. This study presents an account of early peoples in Oregon,...

Diffusion of Eurasian guarding dogs into American agriculture : an alternative method of predator control

Creator:: Lorenz, Jay R.
Abstract:: The diffusion of livestock guarding dogs into American agriculture provides an example of a developed nation adopting a peasant husbandry practice. Guarding dogs, associated with transhumant husbandry, have been used to protect sheep and other livestock from predators in Eurasia for 2000 years. However, they were virtually unknown by Anglo-American...

An Investigation of Photographic Band-Ratioing

Creator:: Fisher, Scott William
Abstract:: A photographic band-ratioing technique was investigated. The data source consisted of 70 mm Landsat Multispectral Scanner (MSS) negatives. The process would require combining registered positive and negative transparencies to achieve a ratio modulation in the resulting print. This would also require compensation for atmospheric effects on the original negatives by...

Transboundary groundwater : geopolitical consequences, commons sense, and the law of the hidden sea

Creator:: Jarvis, William Todd
Abstract:: With 97% of the world’s freshwater resources stored underground, the connection between groundwater resources to the metrics of space, scale and time common to the geographic study of natural resources has not been extensively investigated by geographers. While nearly 240 transboundary aquifers are mapped across the world, a potential “tragedy”...
