Non-linear nitrogen dynamics and calcium depletion along a temperate forest soil nitrogen gradient

Creator:: Sinkhorn, Emily R.
Abstract:: Understanding how N availability influences base cation stores is critical for long-term ecosystem sustainability. Indices of nitrogen (N) availability and the distribution of nutrients in plant biomass, soil, and soil water were examined across ten young, unpolluted Douglas-fir (Pseudotsuga menziesii) stands in the Oregon Coast Range spanning a three-fold soil...

Three essays on the economics of climate change, land use and carbon sequestration

Creator:: Haim, David
Abstract:: This dissertation's three essays explore the effects of climate change on land use changes in the U.S., how future land areas in all major land uses change by projecting land use at the regional scale under two IPCC climate change scenarios. Investigate how and what role should carbon sequestration plays...

The effects of increased supply and emerging technologies in the forest products industry on rural communities in the northwest U.S.

Creator:: Crandall, Mindy S.
Abstract:: The development of a market for currently non-merchantable forest material, such as harvest residues of tops and limbs of trees or small diameter trees, has been suggested as a possible win-win solution that could: (i) provide a financial incentive to help motivate treatments to reduce wildfire risk or restore forest...

Root decomposition in three coniferous forests : effects of substrate quality, temperature, and moisture

Creator:: Chen, Hua
Abstract:: Controls of substrate quality, temperature, and moisture on woody root decomposition in the Pacific Northwest were explored using chronosequences, time series, laboratory incubations, and simulation modeling approaches at three sites: Cascade Head (CAH), H. J. Andrews (HJA), and Pringle Falls Experimental Forests (PRF). In the chronosequence study, a structural component-oriented...

Model III : a sequential approach to joint optimization of the stand treatment and forest level harvest scheduling problem

Creator:: Barber, Richard L.
Abstract:: Harvest scheduling and stand level optimization have generally been regarded as separable problems. Some studies have attempted to jointly optimize a wide range of stand treatments and a forest wide harvest schedule using combinations of mathematical programming techniques. The mathematical programming forest level techniques presume perfect information on production, costs...

Likelihood analysis of the multivariate ordinal probit model for repeated and spatial ordered categorical responses

Creator:: Li, Yonghai
Abstract:: This dissertation is about the likelihood analysis of ordered categorical responses in a longitudinal/spatial study, meaning regression-like analysis when the response variable is categorical with ordered categories, and is measured repeatedly over time or space on the experimental or sampling units. Particular attention is given to the multivariate ordinal probit...

Optimal timber harvesting in uneven-aged forest stands : a discrete-time optimal-control approach

Creator:: Haight, Robert G.
Abstract:: The purpose of this dissertation is to formulate, analyze and numerically solve the dynamic harvesting problem for uneven-aged stands. The problem is to find the optimal numbers of trees to remove from diameter classes over a finite time horizon and is formulated as a discrete-time optimal-control problem with bounded control...

A comparison of the value of forest plans developed under three levels of detail regarding management intentions

Creator:: Hirte, Sarah Rebecca
Abstract:: 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 if a stand-level optimization process is not used to guide the selection of stand management regimes Forest planners thus generally have a...

Local economic impacts of changes in the availability of public timber

Creator:: Eppley, Linda M.
Abstract:: 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 decisions regarding resource use on the National Forest lands can have a major influence on the stability of local...

Tradeoffs associated with managing forested landscapes for multiple-uses

Creator:: Lichtenstein, Mark E.
Abstract:: 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 and costs of alternative management prescriptions. The study examines three watersheds in the Oregon Coast Range and 166 terrestrial...
