Spatially explicit inter-temporal forest management decision under the risk of fire

Creator:: Konoshima, Masashi
Abstract:: This paper presents a framework for analyzing efficient spatial allocation of forest management efforts - fuel treatment and harvest - under the risk of fire. The framework integrates a fire behavior model and a spatially-explicit stochastic dynamic optimization model. I investigate the effects of spatial interaction across plots during forest...

Crown structure, stand dynamics, and production ecology of two species mixtures in the central Oregon Cascades

Creator:: Garber, Sean M.
Abstract:: Knowledge of stand structure, stand dynamics, and production ecology of species mixtures lags well behind that of single-species, even-aged stands. Two mixed-species spacing trials in central Oregon allowed investigation of mixed-species dynamics in a controlled experimental setting. The first site, Pringle Butte, is a mixture of ponderosa pine (Pinus ponderosa...

Spatial patterns of fuel management activities and their effects on wildfire behavior

Creator:: Kim, Young-Hwan
Abstract:: Fuel management has been used as an effective local strategy to reduce the undesirable consequences of wildfires. Many efforts toward scheduling of fuel management activities across a broader landscape have been proposed, with the hope of achieving larger landscape-scale management effects. However, scheduling of fuel management treatments across the broader...

Persistence of western juniper resource islands following canopy removal

Creator:: Miwa, Christopher
Abstract:: Western juniper (Juniperus occidentalis) cover has more than doubled within the last century and currently occupies over 9 million acres in the Intermountain West. Encroachment has altered the spatial distribution of soil nutrients and plants in these systems, forming nutrient enriched 'resource islands,' under tree canopies. The purpose of this...

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...

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...

Citizen perspectives on hazardous fuel reduction in the Blue Mountains : findings and implications from panel research

Creator:: Toman, Eric Lee
Abstract:: Forests in the Blue Mountains region of eastern Oregon and Washington are facing a large-scale forest health crisis. Poor forest conditions have greatly increased the risk of catastrophic wildfire. Resource managers in the Wallowa-Whitman, Umatilla, and Malheur National Forests are utilizing prescribed fire and mechanized thinning treatments to reduce hazardous...

Citizen-agency interactions : an investigation of postfire environments

Creator:: Olsen, Christine Shaw
Abstract:: Wildfire management has grown increasingly complex in recent years, particularly in the West and in the Wildland-Urban Interface (WUI) where a steady population growth has resulted in greater risk to people and property. Recent trends suggest the process of recovering from large fires (>100,000 acres) will become increasingly important to...

Soil compaction in central Oregon volcanic ash soils and the subsequent effects on residual ponderosa pine growth

Creator:: Parker, Robert T.
Abstract:: Although previous research in central Oregon has shown soil compaction can lead to a decline in site productivity, the subject is not understood well enough to predict the growth changes resulting from a given level of soil compaction. A study was initiated to relate the basal area, height and volume...

Historical disturbance regimes as a reference for forest policy

Creator:: Thompson, Jonathan R.
Abstract:: Using the historical range of forest conditions as a reference for managing landscapes has been proposed as a "coarse-filter" approach to biodiversity conservation. By emulating historical disturbance processes, it is thought that forest management can produce forest composition and structure similar to the conditions that once supported the native biota....
