Abstract Key message Hygroscopicity is a crucial element of bark water storage and can reach >60% holding capacity depending on tree species Bark forms the outer layer woody plants, it directly exposed to wetting during rainfall reacts changes in relative humidity, i.e., may exchange with atmosphere through absorption desorption vapor. A current paradigm hydrology suggests that maximum empti...

Wood packaging material (WPM) is a major pathway for international movement of bark- and wood-infesting insects. ISPM 15, the first international standard for treating WPM, was adopted in 2002 and first implemented in the United States in 2006. ISPM 15 allows bark to remain on WPM after treatment, raising concerns that insects could infest after treatment, especially if bark were present. We co...

The chemical compositions of loblolly pine (Pinus taeda L.) bark samples from two industrial sources were determined for whole bark as well as the inner and outer bark components. Differences in extractive contents of the whole bark samples were primarily attributed to the different debarking methods which afforded different proportions of inner and outer bark. Treatment of the extractive-free ...
