Applications of Soil Science in Forest Landscape Planning : Challenges and Opportunities in the 21st Century

Creator:: Craigg, Terry Lee
Abstract:: Soils and other resource programs in both public land management agencies and private industry are continually being adapted to the challenges of evolving knowledge and experience in the field of forestry. This dissertation explores new ways of thinking about and using soils information in forest planning and management, with a...

Impacts of forest practices on surface erosion

Creator:: Sidle, Roy C.
Abstract:: Surface erosion can be initiated by forest practices such as timber harvest, road construction, and site preparation. A variety of management and control measures can help reduce this erosion. Surface erosion is generated by soil and operational conditions that are conducive to or cause disturbance and compaction. By using good...

Soil respiration, carbon and nitrogen leaching, and nitrogen availability in response to harvest intensity and competing vegetation control in Douglas-fir (Pseudotsuga menziesii) forests of the Pacific Northwest

Creator:: Slesak, Robert A.
Abstract:: Management practices following forest harvest can affect long-term soil productivity through alteration of soil carbon (C) and nitrogen (N) pools, but processes contributing to change are poorly understood. I assessed effects of three levels of logging-debris retention in combination with initial or annual applications of competing vegetation control (CVC) following...

Attitudes of forest managers toward dispersed recreation on roaded forest lands in the Pacific Northwest

Creator:: Moutsinas, Cynthia Martha
Abstract:: The purpose of this study was to describe the nature and extent of managers' attitudes toward dispersed recreation, identify reasons for managers' pro and con attitudes and to evaluate factors in the managers' background which might be correlated with their attitudes toward dispersed recreation, Questionnaires distributed via agency were used...

Case studies of red alder and Sitka alder in Douglas-fir plantations : nitrogen fixation and ecosystem production

Creator:: Binkley, Dan
Abstract:: Seven case studies of 11 ecosystems were used to examine the effects of nitrogen-fixing alders in Douglas-fir plantations. The first case study quantified nitrogen (N) fixation and aboveground net primary production in a young Sitka alder [Alnus sinuata (Regel) Rydb.] ecosystem. At 5 yr of age, the N fixation (C₂2H₂...

A comparison of subregional lumber, plywood and log markets in the Douglas-fir region

Creator:: Haven, Lisa
Abstract:: Subregional log market differences are defined and analyzed. Seven demand and seven supply centers are initially specified. Log demand factors inspected are mill capacity, processed wood species, cost and profitability conditions distinguished by product and subregion. They are preliminarily linked to a regional market model through product price transmission. An...

Correlation between structural heterogeneity and arthropod biodiversity : implications for management of Pacific Northwest forests

Creator:: Madson, Stephanie Lee
Abstract:: The "old-growth controversy" in the Pacific Northwest recognized thinning as the primary silvicultural practice for land managers to produce wildlife habitat while continuing to produce timber. For the foreseeable future, forest stands will be harvested to produce forest gaps and a patchwork of trees of different ages. In order to...

Sensitivity of TRIM projections to management and stocking adjustment assumptions

Creator:: Alexander, Susan J.
Abstract:: The Timber Resource Inventory Model (TRIM) is a computer model used by the U.S.D.A. Forest Service in assessing the state of the Nation's forest resources and the forests' probable future conditions. TRIM is a yield table projection system designed and developed to model forest inventory changes over time in response...
