The procedure of forest level harvest scheduling
incorporates many inputs of an uncertain nature. Forest
management planners must be aware of the possible effects of
the use of erroneous input information on the results of
their planning. With that knowledge they can better plan a
risk management strategy and make...
A descriptive model of community stability is developed which
can be used to gauge the achievement of community stability in
federal sustained yield units. Community stability is defined which
provides the framework on which the model was created.
The achievement of the four goals of the 1944 Sustained Yield
Act...
The Timber Resource Analysis System (TRAS) was the
timber supply projection model used in conjunction with
the Timber Assessment Market Model (TAMM) to predict
future U.S. softwood timber harvests, inventories and
product prices in the 1980 RPA Timber Assessment conducted
by the USDA Forest Service. Several criticisms of the
TRAS...
The Forest and Rangeland Renewable Resources Planning Act of 1974 requires the U.S. Forest Service to periodically evaluate the U.S. timber situation. An important part of such studies is the determination of forest product imports from Canada through evaluation of Canadian log and product supply conditions. Other studies have projected...
The objective of this study was to measure the consequences of alternative
forest management intensification programs. These consequences
include future harvest levels, silvicultural labor and capital
requirements, and the income and employment generated directly and indirectly.
The system utilizes the Timber Resource Economic Estimation
System (TREES) model, a harvest scheduling...
The City of Waldport, Oregon, has been periodically exposed to the
effects of marine flooding and erosion. Consequent to the erosion of the
Alsea Bay sandspit during the fall of 1985, one Waldport residential neighborhood
was faced with the imminent threat of serious marine flood inundation.
This study includes a...
The rangelands of the Warm Springs Indian Reservation
represent a major resource within a definitive
geographic area. The utilization of this resource is affected
by a number of factors, some of which are examined
here. The cultural evolution of the Warm Springs people
has resulted in the horse maintaining a...
Oregon's Special Farm Use Assessment program is investigated
in this paper for its effectiveness in preserving farmland from urban
sprawl. Basic research for this study was conducted in Jefferson
County, a rural central Oregon county. Data from a similar study conducted
in Washington County, an urbanizing northern Willamette Valley
county,...
Humboldt County has several areas which have naturally
high to extreme wildland fire hazards. Recent settlement within
these areas increases the likelihood of a destructive fire. This
report examines the extent and degree to which climate, slope and
vegetation influence the wildland fire hazard in Humboldt County,
as well as...
