Canadian lumber producers enjoy access to the North American and overseas markets because of recognition afforded to the lumber quality and conformity assessment system. While the processing of post-mountain pine beetle (MPB) wood under this system is not new, the volume of such wood is unprecedented, as is the duration under which commercial operations must continue to process it. In response to these concerns, including the possibility that new issues may emerge from producing lumber from MPB wood, it is essential to monitor and demonstrate that the lumber quality system continues to meet its obligations, and to follow-up, if deficiencies are detected, with appropriate adjustment for the period over which the MPB-killed stands will be processed.
The Canadian Wood Council is the agency designated by the National Lumber Grades Authority (NLGA) to maintain and provide access to the Canadian In-Grade Lumber database. The proposed work will provide the baseline for the development of protocols for quality assessment through an in-depth analysis of the Canadian In-Grade Lumber databases and an evaluation of data collected from a trial sample targetting MPB-relevant defects.
