The objective of this project was to investigate technical efficiency and productivity growth in the Pacific Northwest sawmilling industry over the period 1968-2002. Productivity growth was decomposed into three componen ...

In the field of forest planning, assumptions regarding the appropriate modeling of management behavior, translated through management prescriptions, minimum harvest ages, green-up periods, and other variables are needed ...

Soil respiration, or the combined CO₂ emissions from roots and soil microorganisms, constitutes one of the largest losses of carbon (C) from terrestrial ecosystems. The major drivers of soil respiration, which include so ...

The objective of this study was to develop a system based on economic criteria for projecting changes in land use areas. The total land base was partitioned among three classes of private forest owners and crop, pastu ...

For many resource-based communities throughout Oregon the timber industry plays an important role. In many of these areas, federal land holdings comprise a large proportion of the area's land holdings. Management deci ...

We monitored larval Lost River and shortnose suckers from natal beds in the Williamson and Sprague rivers to nursery grounds in Upper Klamath Lake. Downstream movements occurred at night, in the middle of the channel, ...

The 2002 Biscuit Fire burned through more than 200,000 ha of mixed conifer/ evergreen hardwood forests in southwestern Oregon and northwestern California. The remarkable size of the fire and the diversity of conditions ...

One traditional problem in forest management is to find the optimal stand level management regime. Four important silvicultural practices including precommercial thinning, commercial thinning, fertilization and regene ...

This study focuses on the tradeoffs that exist for managing forested landscapes for biodiversity and timber production. Tradeoff evaluation is important to natural resource managers so they can understand the benefits an ...

There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it i ...
