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...

A computer simulation study of the relative efficiency of several forest sampling techniques as influenced by the spatial distribution of trees found in five major forest types of the Pacific Northwest

Creator:: Payandeh, Bijan
Abstract:: This study was initiated to determine the relative efficiency of systematic, stratified and simple random sampling for crown area and tree frequency estimation of five of the major forest types found in the Pacific Northwest. Several of the more common methods of estimating spatial distribution coefficients were evaluated. Finally the...

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...

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...

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...

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...

An investigation of factors affecting the optimal output log distribution from mechanical harvesting and processing systems

Creator:: Marshall, Hamish Douglas
Abstract:: Globally the forest harvesting industry is becoming increasingly mechanized. Driving this trend is the desire to increase productivity and reduce cost, as well as to improve labor-related issues. With mechanization comes an in-forest platform for the introduction of state-of-the-art communication and measurement technologies, and powerful on-board computers. These systems have...

Remote sensing of forest biomass dynamics using Landsat-derived disturbance and recovery history and lidar data

Creator:: Pflugmacher, Dirk
Abstract:: Improved monitoring of forest biomass is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, fine spatial grain, and long history of earth observations provide a unique opportunity for measuring biophysical properties of vegetation across large areas and long time scales. However,...

Local and downstream effects of contemporary forest harvesting on streamflow and sediment yield

Creator:: Zégre, Nicolas P.
Abstract:: This dissertation is a collection of three manuscripts that serve to fill the knowledge gaps and advance methods of detecting the effects of contemporary forest harvesting in experimental catchment studies. While there is a preponderance of studies evaluating the environmental effects of forest harvesting in the western United States, few...
