In log grading, what is the heart center?

• A. The central part of the log that should not exceed 40% of the log diameter and must be rot-free.
• B. The outer bark layer.
• C. A decorative feature near the end.
• D. The portion near the base.

Answer: (A)

In log grading, the heart center is the central, sound core of the log that must be free of rot. The standard specifies that this core’s diameter should not exceed 40% of the log’s diameter, and it must be rot-free. This criterion provides a consistent measure of a solid, usable core, helping determine the log’s grade and the amount of high-quality wood available. The outer bark, decorative features, or the portion near the base are not the heart center and aren’t the focus of this definition.
