The presence and characterization of measurement error in forestry

Creator:: Canavan, Sean Joseph
Abstract:: Measurement error (ME) is a component of any study involving the use of actual measurements, but is often not recognized or is ignored. The consequences of MEs on estimates of tree and stand attributes and the parameters and predictions of forest models can be varied and severe, including the presence...

Examination of imputation methods to estimate status and change of forest attributes from paneled inventory data

Creator:: Eskelson, Bianca N. I.
Abstract:: The Forest Inventory and Analysis (FIA) program conducts an annual inventory throughout the United States. In the western United States, 10% of all plots (one panel) are measured annually, and a moving average is used for estimating current condition and change of forest attributes while alternative methods are sought in...

Disaggregative and individual-tree growth models in theory and application

Creator:: Ritchie, Martin W.
Abstract:: Disaggregative and individual-tree/distance-independent modeling methods are compared and contrasted. Differences between the two are related to differences in functional and apparent resolution and may be illustrated using aggregation theory. When considering models of different levels of resolution describing a given phenomenon, invariance with respect to the aggregation implied (symmetry) may...

Light detection and ranging (LiDAR) : what we can and cannot see in the forest for the trees

Creator:: Edson, Curtis B.
Abstract:: Recently concerns over anthropogenic carbon pollution have received increased global attention and research in forest biomass and carbon sequestration has gained momentum. Light Detection and Ranging (LiDAR) remote sensing has in the last decade demonstrated forest measurement and biomass estimation potential. The project objective was to compare LiDAR forest biomass...

Estimation and modeling of selected forest metrics with lidar and Landsat

Creator:: Strunk, Jacob L.
Abstract:: Lidar is able to provide height and cover information which can be used to estimate selected forest attributes precisely. However, for users to evaluate whether the additional cost and complication associated with using Lidar merits adoption requires that the protocol to use lidar be thoroughly described and that a basis...

Comparison of timber tax options available to western Oregon small nonindustrial private forest land owners

Creator:: Cannon, T. Lincoln
Abstract:: Most forests and timber in Western Oregon are taxed under the Western Oregon Forest Land and Severance Tax (WOST), a system which is accepted as one that promotes "correct" economic rotation lengths. This study was motivated by the observation that an optional tax with the same stated purpose - the...

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...

Comparing structure and development of Douglas-fir old-growth, plantations, and young natural forests in western Oregon

Creator:: Dowling, Christopher D.
Abstract:: Ages, diameter growth, density, tree size, and species were studied in old-growth, plantation, and young natural Douglas-fir stands in three areas in western Oregon: the western and eastern Coast Range and the western Cascades. The purpose was to compare the development of these three stand types and to determine whether...

Yield and financial analysis of "New forestry" techniques on the McDonald and Dunn Forests

Creator:: Bartlett, David M.
Abstract:: In the Pacific Northwest, a transition has begun that is shifting many practices in forest management. Traditionally, harvesting and regeneration has been done through clearcutting which removes all trees in the area being cut and plants an entirely new stand. Clearcutting is often the most efficient method for harvesting forests...

Federal forest revenue-sharing in coastal Oregon : an assessment of historical and future tax equivalence

Creator:: Powell, Leslie A. (Leslie Ann)
Abstract:: Public land ownership withdraws property from the tax base of local property tax districts. Publicly-managed lands occupy approximately 17.5 million acres of forested lands in Oregon (inclusive of federal, state, and county ownership). To compensate local taxing districts for foregone property tax collections, Congress enacted a series of federal revenue-sharing...
