Estimating volume and value on standing timber in hybrid poplar plantations using terrestrial laser scanning : a case study

Creator:: Barnett, Jennifer S.
Abstract:: Terrestrial laser scanning (TLS) may provide a way to increase timber value recovery by replacing manual timber cruising with a simple-to-use, cost-effective alternative. TLS has been studied in several trials worldwide. Past studies have not compared TLS based estimates with mill estimates of stem value and volume. Three differently stocked...

Managing woody biomass transportation for improved biomass economics

Creator:: Han, Sang-Kyun
Abstract:: With rising fuel costs and enhanced environmental concerns, the use of renewable energy has been steadily considered and widely expounded as a solution to the challenges of global energy security and climate change. The use of woody biomass, in particular, has received considerable attention for energy production due to the...

Estimating spatial changes in acoustic velocity in felled Douglas-fir stems

Creator:: Dowding, Bodie
Abstract:: To compete with other building materials, the wood products industry must find a way to increase value and lower costs. Wood stiffness is important for most wood uses. Value can be increased and costs can be lowered by sorting logs for stiffness in the woods using acoustic devices mounted on...

Modeling air-drying of Douglas-fir and hybrid poplar biomass in Oregon

Creator:: Kim, Dong-Wook
Abstract:: Both transportation costs and market values of woody biomass are strongly linked to the amount of moisture in the woody biomass. Therefore, managing moisture in the woody biomass well can lead to significant advantages in the woody biomass energy business. In this study, two prediction models were developed to estimate...

Forest biomass estimation with hemispherical photography for multiple forest types and various atmospheric conditions

Creator:: Clark, Joshua Andrew
Abstract:: The importance of accurately identifying inventories of domestic energy, including forest biomass, has increasingly become a priority of the US government and its citizens as the cost of fossil fuels has risen. It is useful to identify which of these resources can be processed and transported at the lowest cost...

Evaluation of six tools for estimating woody biomass moisture content

Creator:: Becerra Ochoa, Fernando Amador
Abstract:: Woody biomass transportation costs and market values/costs are strongly correlated with the woody biomass moisture content. Properly managing moisture content can potentially lead to economic and environmental advantages in biomass energy markets. Good management requires accurate moisture content measurements. Therefore, availability of accurate, precise, reliable, and efficient tools to assess...

Opportunities and challenges for decision support systems in log truck scheduling and dispatching

Creator:: Kokenge, Kyler S.
Abstract:: The transportation of logs from the forest to the mill accounts for 25-50% of the delivered cost of wood, depending mostly on haul distance. Decision support systems (DSS) for log truck scheduling and dispatching have the potential to reduce transportation costs by optimally constructing routes, also known as schedules for...

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...

Analysis and operational considerations of biomass extraction on steep terrain in western Oregon

Creator:: Flint, Benjamin R.
Abstract:: The development of bioenergy from biomass has dominated the minds of forest engineering researchers over the last decade. One of the main themes that has been generated from that research is that bioenergy from biomass has major operational hurdles to overcome before becoming economically feasible. More directly, the impact of...

Direct stakeholder perceptions of collaboration, indicators, and compliance associated with the wilderness best management practices in Tracy Arm-Fords Terror Wilderness, Alaska

Creator:: Pomeranz, Emily F.
Abstract:: Increasingly popular methods for managing impacts of tourism in nature-based settings include collaborative and voluntary codes of conduct. In southeast Alaska, for example, the Tourism Best Management Practices (TBMP) in Juneau and Wilderness Best Management Practices (WBMP) in Tracy Arm-Fords Terror Wilderness have been created to address shore and marine...
