As the demands for forest products increase, additional timber harvesting operations can be expected on steep mountainous terrain, The resulting disruption of natural slope stability by man's disturbances (roadbuilding, logging and vegetative manipulation, etc.) may also accelerate mass movement processes in this terrain. Swanston (1969) defines mass movement as ".,...
Commercial thinning young growth forests is an increasingly
important silvicultural technique for improving second growth
management of Douglas-fir stands. Research aimed at advancing the
efficiency of skyline logging operations in small wood timber stands
is essential in order to make thinning these young stands economical.
The purpose of this study...
The preparation of suitable sites for planting and growing of tree seedlings following logging is recognized by British Columbia Forest Service as a major silvicultural problem in the Central and Northern Interior regions of the province. Over the past few decades, scarification trials have been made with various types of...
The objective of this project was to determine the limitations of the distillation equipment available and to design suitable experiments for chemical engineering students with these limitations in mind. This paper, then, serves as an operating manual and reference guide to the use of the glass distillation equipment and the...
The purpose of this paper is to show the amount of land use change taking place between 1963 and 19714. in T. 11 S.,R. 14- W., W.M., which is located between Albany and Corvallis. The changes of primary interest involve the shifts of agricultural land to residential, commercial and industrial...
The objective of this paper is to examine the
differences in personality between Cannon Beach and Seaside,
Oregon The problem is approached by examining the physical
setting, historical background and a segment of the attraction
mix of each community The combination of site characteristics
and historical development has played an...
The arts and festivals of art have today become a vital economic
force in some areas of the country and a way of life for some people.
The number and sizes of festivals, as well as audience size, has
grown tremendously both nationally and in Oregon, since 1950. Even
the...
Based on a pilot study completed near Heceta
Beach, Oregon, guidelines have been proposed for
the development of Oregon coastal sand areas.
The guidelines, in the form of performance standards
are designed with respect to the variability of
coastal sand areas. Landscape units and vegetation
associations were grouped to reflect...
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.
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...
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 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...
The proposed Santiam Bar Natural Area Preserve
is located at the confluence of the Luckiamute, Santiam,
and Willamette Rivers in Polk and Marion Counties, Oregon,
It is situated on a peninsula supporting riparian and lower
terrace vegetation and associated wildlife. Former use
included forestry and agriculture. Present and proposed use...
The cities of Corvallis and Philomath, Oregon,
have, over the last three decades, grown both spatially
and in numbers of people. This study examines the
attractions and constraints to growth between the two
cities. The most notable constraint to growth is the
fact that the soils in the study area...
Recent judicial decisions give the
treaty Indians in Oregon the right to fifty
percent of the fish destined to reach their
fishing areas. Oregon fish resource managers
are considering various regulation options designed
to assure the Indians their share.
Stricter ocean fishing regulations and more
sophisticated management techniques will have...
The surface mining of coal has accelerated in
northwest Colorado to the point where public pressure
plus impending state and federal regulations dictate the
need for comprehensive reclamation plans. A large coal
company operating in Moffat County has solicited recommendations
concerning soils, hydrogeology, geomorphology,
aesthetics, wildlife, vegetation, microclimatology, and
legal...
The preservation of land, such as wetlands and agricultural
lands, is often pursued through traditional methods such as zoning or
eminent domain. Transferable Development Rights provides a different
approach to the preservation of land by allowing the sale and transfer
of development rights from land to be protected to land...
The objective of this study is to
answer four questions concerning the transportation
network on the Willamette National Forest. These
questions are 1) how many and what kind of roads
exist on the forest, 2) how much annual traffic
can these existing roads handle, 3) can the
existing system handle...
Land value appreciation and its relation to three
interchanges on Interstate 5 were studied. Lots within a
two mile (3.2 km.) radius and in existence in 1965 and 1975
were included. The interchanges were selected on the basis
of form, setting, type of crossroad, and distance from urban
areas. Lots...
Lincoln City, Oregon is an area of active environmental
processes and increasing development. To reduce conflict, a larger
data base on environmental hazards was required. Previous studies
in the area, remote sensing techniques and. field research were used
to accomplish this end. Within Lincoln City, numerous environmental
hazards were identified...
Since the passage of the mining and mineral leasing
laws, a considerable amount of the public domain has been
excluded from mineral exploration and development. It has been
estimated that as much as fifty-three and sixty-four percent
of the public lands have been withdrawn from the jurisdiction
of the mining...
The intent of "Oregon Port Districts: An Economic Profile" is to present
a profile of the activities of the Oregon Port Districts and to evaluate
some of the economic contributions that port district operations made in
1975. The study reflects the present role of the port districts within
their community...
Estuaries, an important part of the continental shelf, have been
important centers for the economic development of man. They serve
as an interface between the terrestrial and oceanic realm and are a
part of the ocean that receives the most physical damage.
