What type of wood decay can soft rot cause?

1. Decays dried wooden structures

2. Attacks green saturated wood

3. Only affects hardwoods

4. None, it is harmless

The correct answer is: Attacks green saturated wood

Soft rot specifically targets green, saturated wood, which is wood that retains a high moisture content. This type of decay is primarily caused by certain fungal species that thrive in moist environments and are capable of breaking down the cellulose and hemicellulose components of wood. Unlike other forms of wood decay, such as brown rot or white rot, which might affect the overall structure of the wood regardless of its moisture content, soft rot is particularly effective in conditions where wood remains wet or damp for extended periods. Additionally, soft rot fungi are often found in environments where there is constant moisture, such as in landscaping timbers, wooden boats, and underground wood, thus making them a significant threat to structures or materials that are not properly dried or protected. This unique affinity for moist, unseasoned wood differentiates soft rot from other decay types and emphasizes the importance of moisture control in preventing wood damage.
