Where is white pocket rot usually found?

White pocket rot is typically found in standing timber, particularly in trees that have sustained some form of injury or stress. This type of rot is caused by certain fungi that thrive in the living wood of the tree. The fungi enter through wounds in the bark or areas that have been compromised by insect damage or environmental factors, leading to decay that is characterized by its distinctive white coloration and pockets within the wood.

The environmental conditions within standing timber, such as moisture content and the tree's health, create an ideal environment for the development of this type of rot. When wood is still part of a living tree, it is more susceptible to fungal invasions, and white pocket rot can often be detected before the tree is cut or otherwise harvested.

In contrast, the other options represent conditions that are less conducive to the growth of white pocket rot. For instance, dry wood is typically unfavorable for fungal growth due to lack of moisture, freshly cut lumber may not have enough time for colonization before it is processed or dried, and damp soil, while it can promote other types of rot and decay organisms, is not specifically associated with white pocket rot, which prefers the living tissue and structure of standing timber.
