Characterizing Uncertainty and Assessing the Impact of Rapid Climate Change on the Distribution of Important Tree Species in the Pacific Northwest

Creator:: Kralicek, Karin M.
Abstract:: Climate change will impact the location of suitable habitat for tree species in the Pacific Northwest. Locations that become unsuitable will experience increased levels of tree mortality and diminished levels of tree growth. Understanding how these impacts will spatially manifest is vital for efficient management of natural resources. An invaluable...

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...

An examination of several methods of quantifying forest structure in headwater riparian forests of western Oregon

Creator:: Haxton, Zane A.
Abstract:: Headwater streams are generally small, first-order streams that can comprise up to 80% (by stream length) of the drainage network in mountainous areas of the Pacific Northwest. These streams are intimately connected with downstream reaches, serving as a source of sediment, woody debris, organic matter and nutrients. The surrounding forests...

Effects of Subsampling Trees and Imputation Methods on the Accuracy of Height-to-Crown-Base Predictions for Douglas-fir in Southwest Oregon

Creator:: Allensworth, Elijah J.
Abstract:: Accurate estimates of height-to-crown-base (HTCB) are essential for the reliable projections of stand structure over time required for sustainable forest management. Yet, HTCB often measured alongside total height (HT) for only for a subsample of trees in traditional stand-based inventories and must be imputed for all others. We compared the...

Aerial Laser Scanning for Forest Inventories: Estimation and Uncertainty at Multiple Scales

Creator:: Frank, Bryce M.
Abstract:: As remote sensing data continues to proliferate, development and assessment of methods that generate predictions of forest attributes is needed to inform operational use. For several decades, lidar data collected from aerial platforms has informed assessments of forest resources, but many opportunities remain for the technology. We examine and develop...

Analysis of Fire Severity in Southwestern Oregon Using Aerial LiDAR

Creator:: Wolken, Karin M.
Abstract:: Acquiring, maintaining, disseminating, and utilizing quality data is key to adequate understanding and management of ecosystems. Modern remote sensing technology provides us an increasingly cost effective, unique opportunity for acquiring highly detailed information across every square meter of a landscape. The plethora of data available to scientists allows for use...

Estimating Forest Inventory Attributes Using Airborne LiDAR in Southwestern Oregon

Creator:: Shin, Joonghoon
Abstract:: This thesis mainly consists of two parts: (1) comparing statistical modeling methods based on the area-based approach (ABA) for predicting forest inventory attributes using airborne light detection and ranging (LiDAR) data (Chapter 2), and (2) suggesting a new methodology fusing the individual tree detection (ITD) approach and the ABA for...

Evaluation of Taper and Volume Estimation Techniques for Ponderosa Pine in Eastern Oregon and Eastern Washington.

Creator:: Pancoast, Alexander D.
Abstract:: The growing need for accurate forest biomass and carbon estimates has sparked a recent re-examination of direct volume estimation and taper modeling techniques. Additionally, the need for increased precision of biomass and carbon estimates drives a need to improve the techniques used to evaluate these models. Taper equations have an...

Quantifying Aboveground Biomass for Common Shrubs in Northeastern California

Creator:: Huff, Steven
Abstract:: Quantifying biomass is important for sustainable forest management. The purpose of this study is to obtain allometric relationships for seven species of shrubs common in northeastern California so that estimates of carbon and fuel loading may be better realized. Although some shrub biomass equations exist, such equations are limited in...

Strategies for sampling and estimation of aboveground tree biomass

Creator:: Poudel, Krishna Prasad
Abstract:: The issue of global climate change and an increasing interest in the reduction of fossil fuel carbon dioxide emissions by using forest biomass for energy production has increased the importance of quantifying forest biomass in recent years. The official U.S. forest carbon reporting is based on the forest biomass estimates...
