New report on logging utilization in Idaho

Front cover of report
Front cover of report

Logging utilization studies describe how trees are harvested in commercial operations and account for how the various tree parts are used. This information helps land managers evaluate their logging operations and can reveal utilization trends over time and within various regions.

Logging utilization data is particularly valuable to NARA researchers because it provides a basis used …more

Transportation of residues: would you bundle?

By: Janna Loeppky, M.S. Candidate, Oregon State University

In the forest industry, timber harvesting supplies the demand for one of the world’s most renewable resources: logs. Although the majority of consumers may only know about the final products purchased from mills and lumberyards, the harvesting operation is quite extensive. From stump to mill, the costs for extracting desirable trees to fulfill market demand range in cost depending on the size of the unit being harvested and the amount of …more

Estimating nutrient removals under varying intensities of harvesting residue utilization

By: Janna Loeppky, M.F. Candidate, Oregon State University

Nitrogen is the most abundant atmospheric element and a major nutrient required for plant and tree growth. The vast majority of nitrogen in forest soils and tree biomass is fixed from the atmosphere by soil micro‐organisms. Although the vast majority of nitrogen in most forest ecosystems is held in soil organic matter, some sites contain larger portions in live biomass and may therefore be susceptible to reductions in long‐term site productivity …more

Undergraduate interns contribute to NARA

NARA funds educational opportunities for students at all levels — grade school through college graduate. For the past three years, NARA has provided summer research internships to college undergraduates through the NARA SURE program. SURE (Summer Undergraduate Research Experience) is a program coordinated by Washington State University that provides research internships to undergraduate students throughout the United States and is funded by multiple organizations including NARA.

For the summer of 2014, NARA funded five undergraduate students to conduct research …more

NARA investigates conversion technologies that rely on enzymes called cellulases. Cellulases break down the cellulose and hemicellulose polymers found in wood and release simple sugars. The simple sugars can then be used to make …more

Screening Douglas-fir trees for production of biofuels and other valuable chemicals

Douglas-fir core samples used to determine recalcitrance variability.
Douglas-fir core samples used to determine recalcitrance variability.

Douglas-fir trees are not all alike. Some grow faster, some adapt better to harsher climates and they all differ somewhat in their chemical makeup. These distinctions are due to variations in their genetic makeup. Those interested in breeding plantation trees for timber value have capitalized on genetic …more
