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...

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...

Relationship between allometric variables and biomass in western juniper (Juniperus occidentalis)

Creator:: Sabin, Breanna S.
Abstract:: A tenfold expansion of western juniper (Juniperus occidentalis spp. occidentalis) into the sagebrush steppe has led to the degradation of the economic and ecological potential of these landscapes. Land managers have enacted numerous methods to reduce distributions and densities of these trees. Assessment of above ground juniper biomass, expressed overall...

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...

Sustainable biomass supply from fuel reduction treatments : a biomass assessment of federally owned land in eastern Oregon

Creator:: Vogler, Kevin C.
Abstract:: Wildfire exclusion over the past century or more has resulted in extensive fuel accumulations throughout much of the West that combined with recent climatic patterns have increased the frequency of relatively uncommon, large, high-severity wildfires. Forest restoration treatments intended to alter landscape-level fire disturbance patterns can be difficult to implement...

Converting forest biomass to energy in Oregon : stakeholder perspectives on a growing movement

Creator:: Stidham, Melanie
Abstract:: Within Oregon there is considerable interest in the possibility of converting woody biomass to energy. This interest stems from three converging factors: the desire to reduce the threat of uncharacteristic wildfire by removing excess material from the forests, the possibility to stimulate rural economies that are dependent on forest products,...

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...

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...
