California Black Oak Drying Problems and the Bacterial Factor.

Abstract

This paper reports on a cooperative study between the U.S. Forest Products Laboratory (FPL) and the Kimberly-Clark Corporation to explore the causes and extent of drying degrade in 4/4 black oak lumber from several different saw timber stands in Shasta County, California. Most drying degrade in this study was traced to heartwood that was weakened by anaerobic bacteria in the living tree. We believe bacterial tree infections may be responsible for most of the unexpected drying degrade in California black oak lumber in general.
