Which statement is true about hardwood burning and the heart rot concept?

• A. Hardwoods will always die when duff layer is burned
• B. Hardwoods are immune to fire
• C. Heart rot occurs with hardwood burning
• D. Wind moves the same through trees as at the edge

Answer: (C)

Heart rot is decay inside the heartwood caused by fungi, and it's a common condition in hardwoods. When a burn occurs, heat and surface damage can expose or worsen this inner decay, so you’re likely to encounter heart rot in hardwoods in the context of fire. This makes the statement true because fire can interact with existing heartwood decay in hardwoods, whereas the other ideas—hardwoods always dying from burning the duff, hardwoods being immune to fire, or wind behaving the same inside a stand as at the edge—aren't accurate in fire science and forest dynamics.
