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 purpose of this research was to develop methods for using geographic information system (GIS) analysis and unsupervised classification of Global Vegetation Index (GVI) images to improve carbon budget estimates of the former Soviet Union (FSU). A GIS was used to locate the geographic distribution and estimate the area of...
Streamflow variability can provide valuable information for nonpoint source
pollution monitoring program planning. The research papers presented in this thesis
examine selected properties of streamflow variability in Oregon to advance its application
in regional planning of water quality monitoring programs. The products of this research
depict Oregon streams by their...
Field Automation is an evolving set of geographic information system
(GIS) technologies, including mobile computing and the global positioning system,
addressing operational and environmental applications in the field. This research
involves designing, developing, implementing, and evaluating an environmental and
facility application field automated GIS. The Camp Rilea National Guard base,...
El Niflo and La Nifia are oceanographic and atmospheric phenomena that have been
catalogued for well over a centuly. In El Nifio years, Peru's otherwise thy west coast is
subjected to torrential rainfall. Higher ocean temperatures off the coast are deemed the
culprit. Attempts to quantify this began in the...
