What moisture content is generally considered manageable for fungal growth?

A moisture content of 30% is generally considered manageable for fungal growth because it falls within the range where many types of fungi, including wood-decaying fungi, thrive. Fungi require moisture to grow, and the 30% threshold creates an environment conducive for their colonization and development.

When the moisture content of wood is at or below 20%, fungal growth is usually inhibited, as most fungi cannot thrive in such dry conditions. On the other hand, moisture content above 30% provides sufficient water for fungi to metabolize and reproduce, thus increasing the risk of wood damage. Although the moisture content is closely tied to environmental conditions, understanding these thresholds allows for better management practices when it comes to maintaining structural integrity and preventing infestations.
