Carbon storage and fluxes in forests of western Oregon : successional patterns and environmental controls

Creator:: Van Tuyl, Steven
Abstract:: In this study we use a combination of data from forest inventories, intensive chronosequences, extensive sites, and remote sensing, to make estimates of biomass and net primary production (NPP) for the forested region of Western Oregon. Plot-level forest inventory data were provided by the USDA Forest Service through their Forest...

Evaluating the accuracy of imputed forest biomass estimates at the project level

Creator:: Gagliasso, Donald
Abstract:: Various methods have been used to estimate the amount of above ground forest biomass across landscapes and to create biomass maps for specific stands or pixels across ownership or project areas. Without an accurate estimation method, land managers might end up with incorrect biomass estimate maps, which could lead them...

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...

Testing two applications of image analysis for use in species-independent biomass equations for western Oregon forests

Creator:: Gray, John Edward, 1946-
Abstract:: Remote sensing technologies have proven useful and cost-efficient for quantifying various forest vegetation characteristics over multiple scales. However, significant limitations were encountered in each of two related experiments conducted to explore their potential to supplement or replace traditional, single-species biomass equations for estimation of ground vegetation and tree overstory on...

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,...

Modeling the fixed bed drying characteristics of biomass particles

Creator:: Yang, Hai
Abstract:: The fixed bed drying of western hemlock and Douglas-fir biomass particles at temperatures ranging from 50°C to 200°C and air velocities from 0.3 to 0.9 m/s was investigated. The objectives were to describe the drying characteristics of the particles, fit a model for thin-layer drying, and develop and test a...

Spatially-explicit prediction of recoverable harvesting residues

Creator:: Schmidt, Christian F. W.
Abstract:: In order to decide whether or not to develop biomass energy facilities and where to best locate them, developers and investors need accurate assessments of fuel supply. This includes information about the distribution and concentration of fuel throughout the assessment area, the quality of fuel (form, moisture content, contaminant content,...

Inter-annual variability of net primary productivity across multiple spatial scales in the western Oregon Cascades : methods of estimation and examination of spatial coherence

Creator:: Woolley, Travis J.
Abstract:: Quantifying and modeling processes involved in the global carbon cycle is important to evaluate the temporal and spatial variability of these processes and understand the effect of this variability on future response to changing climate and land use patterns. Biomass accumulation and Net Primary Productivity (NPP) are large components of...
