This book reviews the current state-of-the-art within each of the four major themes: science and policy; inventory and monitoring; statistics and modelling; and information and knowledge management, in the context of sustainable forestry. It fosters dialogue across thematic areas concerning both strategic and operational approaches to integrate research on sustainable forestry. It also enhances and encourages international collaboration towards sustainable forestry practice worldwide.

Nondestructive Methods for Detecting Defects in Softwood Logs

Wood degradation and defects, such as voids and knots, affect the quality and processing time of lumber. The ability to detect internal defects in the log can save mills time and processing costs. In this study, we investigated three nondestructive evaluation techniques for detecting internal wood defects. Sound wave transmission, x-ray computed tomography, and impulse radar were used to examine white spruce and balsam fir logs. Computed tomography resulted in the highest resolution for voids, knots, and high moisture content areas, but at a very high price. Both sound wave transmission and impulse radar were able to detect large voids and areas of degradation, and these techniques showed some sensitivity to very knotty logs. None of the methods was able to detect small pockets of decay. The use of radar requires an experienced operator because of the difficulty of interpreting the data.

Measuring Soil and Tree Temperatures During Prescribed Fires with Thermocouple Probes

Soil and cambium temperatures must be known to ascertain certain effects of prescribed fires on trees. Thermocouple-based systems were devised for measuring soil and cambium temperatures during prescribed fires. The systems, which incorporate both commercially available and custom components, perform three basic functions: data collection, data retrieval, and data translation. Although the systems and procedures for using them were designed for research purposes, they could be adapted for monitoring operational prescribed fires.
