The Sacagawea testbed has been designed to support testing and development of decision making models, and associated uncertainty management techniques, that are appropriate under real-time problem solving constraints. Conceptually, it provides a simulated temporal and spatial environment, the latter consisting of a terrain grid of elevation and tree cover data,...

Regression equations for estimating the aboveground biomass (ovendry weight) of individual plants of 10 shrub and 2 pine species were developed from data collected in south central Oregon. All include a single independent variable and were generated from logarithmically transformed data. Total aboveground biomass of each shrub species is predicted...
Soil organic matter levels, soil temperature and moisture, and vegetation properties were measured along a sequence of death and
regeneration in a mountain hemlock (Tsuga mertensiana) forest. The sequence is produced by slowly moving waves of the root pathogen Phellinus weirii. While analysis of variance for all sampled soil layers...
The Distributed Testing Coordinator (DTC) is a system for control and coordination of the software testing processes at Rogue Wave. Some important features in this product include automatic resource configuration, centralized job scheduling, concurrent and distributed testing, failure recovery, and automatic event logging and test reporting.
DTC consists of a...
The National Forest System (NFS) of the United States plays an important role in the carbon cycle because
these lands make up a large proportion of the forested land in the country and commonly store more wood
per unit area than other forest ownerships. In addition to sustaining natural resources,...
This study considers trade-offs between timber harvest and carbon
sequestration on National Forest and other public lands by contemporaneously linking
a model of public harvest and inventory to a carbon accounting system. The public
harvest model treats three harvest scenarios. The first minimizes the cost of meeting
harvest requests that...
Fire is a fundamental disturbance that drives terrestrial and atmospheric carbon dynamics. Previous studies have quantified fire effects on carbon cycling from local to global scales but have focused nearly exclusively on high-severity, stand-replacement fire. Since 2002, variable-severity wildfires have burned more than 65 000 ha across the east slope...
This study considered regional forest policies for sequestering carbon in existing
forests in western Oregon. A model of log markets in western Oregon was employed to
examine the impacts of forest policy changes on future carbon stock, harvests, and
management activities. A carbon tax program, as a mitigation option for...
