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

Smart tools to measure slash pile volumes

slash pile copy

A woodland owner has a choice of time tested measuring techniques to predict how much lumber can be produced from trees. Accurate volume estimates can help forest managers plan for the number and type of trees to harvest and the appropriate workforce and equipment needed.

NARA provides technical assistance to an emerging industry that, instead of using the bole wood (trunk) for lumber, uses the wood …more

Harvesting forest residuals: environmental impacts and sustainability

Processing forest residuas
Processing forest residuas

Typically when trees are harvested for lumber and pulp, the limbs and branches (commonly termed “forest residuals”) are left on the forest floor or collected in slash piles and burned. If these forest residuals were used instead to produce products such as biojet fuel, what effect would that have on our environment and how can we manage the …more
