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.
This thesis research consists of an investigation of the human
influences on wildlife in Belize. The study was accomplished by the
collection and analysis of data with respect to land use, habitat
characteristics, and wildlife status in Belize. Requirements and
status of many species are tabulated in order to give...
Stream channel stability for two tributaries of Rock Creek in the
Oregon Coast Range is evaluated by application of a Stream Reach Inventory.
Stability nomographs are constructed for graphical analysis of
erosion potential. Results indicate that channel stability can be
classified. One stream is rated as 'Poor' in resistance to...
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...
Between 1967 and 1973, California, Oregon,
and Washington all established state-wide systems for
the preservation of land in its natural state. These
set aside parcels of land may be termed as Natural
Area Preserves. The history of each state's public
systems, different establishment procedures, and
management policies are discussed.
The crawfish enterprise of South Louisiana is shown to haveexpanded as much as 18-fold since the 1950's. It is estimated(1973) that there are about 44,000 acres of managed crawfish ponds.Of the 334 ponds identified and mapped in the thesis, 231 are classedas open ponds, 45 as rice field ponds, and...
A method for analyzing growth of an urban area is
developed. Albany, Oregon, from 1936 to 1975 was used as a test
case. The method employs the use of remotely sense imagery
combined with an analysis of selected physical characteristics
of the land being urbanized. The study consists of an...
There are conflicts between commercial and agricultural
uses of land bordering U. S. Highway 201 southbound from
Ontario, Oregon. A questionnaire was developed and administered
to businesses located along Highway 201 to determine the most
important location factors for commercial users of the ribbon
development. The most important factors were...
Conflict and competition between outdoor recreational activities is increasing in intensity. Thus, management agencies and persons responsible for regulation of outdoor recreation areas have become increasingly concerned and are seeking appropriate means for amelioration of the intensifying problem.
This research was designed to seek better understanding of conflicts and incompatabilities...
A statistical analysis of extreme chinooks in Montana as they
relate to large scale atmospheric circulation changes is the subject
of this thesis.
A mean chinook situation was identified which indicated that a
critical pattern of the surface flow always contained a Polar or
Arctic airmass which overspread the prairie...
Farm Use Assessment used as a planning tool to preserve
farmland in Oregon has achieved mixed success. While some land enrolled
in the program (especially near urban areas) has been converted to nonfarm
use, the majority of land has not. However, this may be due to
lack of '1opportunity profits"...
Seven socioeconomic factors common to two Oregon
communities, Beaverton and Corvallis, were examined and
compared for the influences they might have on participation
in recycling programs. Sampling technique involved
the use of a prepared survey questionnaire through which
the data necessary for the appropriate statistical methodology
used in the study...
Many of the natural resource problems facing man in the present
era are so large and complicated that no one discipline provides an
adequate approach for their solutions. As an example, the relationships
of man to the land resource base can best be understood when
they are considered holistically rather...
Expansion of the National Flood Insurance Program is
described in the context of a modification of Kates' Systems Model of
Human Adjustments to Natural Hazards for a small central Pennsylvania
town (1970 population=ll,O98) that became eligible for flood insurance
four months after experiencing five million dollars in flood damage
and...
The two classic theories of the distribution of
cities in an urban system are the rank size rule
and central place theory. The rank size relationships,
as incorporated into G. K. Zipf's Principle
of Least Effort, is seen as the result of a balancing
of the opposing forces of urban...
The Upper Kiamath Valley and Klamath Marsh areas of
south-central Oregon comprise the summer range for a modern
system of transhumance agriculture. Approximately 72,000
head of cattle are annually trucked from these relatively
small Kiamath pastures to winter pastures scattered throughout
the Sacramento Valley. Field research indicates that
the development...
There is a considerable amount of vacant land
zoned for industrial use within the Corvallis Urban Growth
Boundary. A detailed investigation of the area reveals
a total of 632.98 acres of such land. However, when closely
scrutinized, it appears that the total number of acres is
misleading, as only 77.50...
Limited measures of socio-economic affluence
among some Oregon counties reflect deficiency in the
availability and development of agricultural resources.
Seventeen indicators qualify county census data into
comparable relative values. Rank correlation analysis
of the relationship between agricultural resources and
socio-economic affluence demonstrates a significant
correlation coefficient at the 95 percent...
This paper is an analysis of the resource use
conflict of the Columbia River salmon fishery. The report
discusses the physical setting of the Columbia River, the
biology of anadromous salmon, the history of the resource
use, hazards to the salmon, fishing techniques, and salmon
usage today with its conflicts,...
Signification temperature differences were found to exist among three similarly situated stations in the Mid-Willamette Valley of Oregon. The stations were McMinnville, Salem, and Corvallis. Factors known to influence temperatures were compared with the temperature differences of the stations using available weather data. Factors examined included elevation, latitude, cloud cover,...
