Stand level silvicultural optimization utilizing a late-seral index constraint

Creator:: Semeliss, Wade Alan
Abstract:: A dynamic programming algorithm (MS PATH) was used to develop a stand level optimization model, FPS Optimizer. The model incorporates a late-seral constraint on the profit maximizing objective function utilizing a four-descriptor structural index as a proxy. This index, the 'Old-Growth Index', rates the late-seral structural quality of a given...

Economic analysis of integrating spatial concerns into harvest scheduling

Creator:: Yoshimoto, Atsushi
Abstract:: An analytical algorithm to formulate a sparser set of adjacency constraints than the conventional algorithm is proposed. Utilizing matrix algebra applied to an adjacency matrix, constraints are systematically and efficiently derived by the proposed algorithm. The proposed algorithm is proved to provide a true set of adjacency constraints in the...

Value, volume, and jobs : a comprehensive assessment of wood fiber and residue utilization within Oregon: 1992

Creator:: Ross, Janet R.
Abstract:: Oregon's forest product industry continues to be the nation's number one producer of wood products. The forest products industry contributes significantly to Oregon's economy. Changes in timber supply, land use policy, technology, and product demand create significant impacts on the region. The activities of the wood products industry translate into...

An analysis of technical efficiency and productivity growth in the Pacific Northwest sawmill industry

Creator:: Helvoigt, Ted L.
Abstract:: 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 components: technical change, efficiency change, and scale efficiency change. In addition, using econometric methods, changes in output elasticities and input substitution...

Measuring costs of sequestering carbon in forest stands with different management regimes in western Oregon

Creator:: Zyrina, Olga A.
Abstract:: This project was a part of larger work that compared major factors controlling patterns of carbon dynamics in two regions of the globe, the Pacific Northwest, USA and northwestern Russia. It was funded through the NASA foundation (grant # NAG5- 6242). Human economic activity is causing the release of pollutants...

A multivariate control solution to the mixed species/diameter class thinning and final rotation problem

Creator:: Cousar, Paul K.
Abstract:: The algorithm RLS-PLUS was developed to yield solutions to the multivariate control problem of diameter and species optimization for mixed conifer and hardwood stands. The problem is specified with twenty-five state variables consisting of five species groups with four merchantable diameter classes and one unmerchantable class. This gives twenty diameter...

An economic analysis of whitewater recreation on the upper Klamath River

Creator:: Moore, Eric M.
Abstract:: Resource managers and decisionmakers must often decide how to allocate and manage conflicting uses of scarce natural resources. In many cases, one use of a natural resource precludes alternative uses of the same resource. In order to make informed decisions regarding the allocation and management of such scarce natural resources,...

An analysis of the motivations of Oregon's ranchers to diversify into agritourism

Creator:: Pegas, Fernanda de Vasconcellos
Abstract:: Agritourism is one way to sustainably conserve open space. Its potential to supplement Oregon ranchers’ income may also preserve ranching culture. Research on agritourism in Oregon and elsewhere, however, is scarce. This study focused on the motivations of Oregon ranchers to diversify into agritourism, the congruence of conservation easements and...

The economics of carbon sequestration in western Oregon forests

Creator:: Im, Eun Ho
Abstract:: 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...

Livelihoods and land use change in highland Ethiopia

Creator:: Guillozet, Kathleen
Abstract:: This dissertation investigates livelihood and land use change dynamics in a community at the farm-forest periphery in highland Ethiopia. I use interviews and livelihood assessment data to compare the strategies used by members of different wealth groups to negotiate and maintain access to forest resources, and integrate socioeconomic, bio-physical and...
