Explanation: 

Detailed explanation-1: -Measure DBH below the branch or bump. The USFS measures DBH immediately above point where bumps or branches cease to affect diameter of the stem. The underlying concept is to measure the diameter that would be closest to the expected DBH if branches or other irregularities were not present.

Detailed explanation-2: -→ The diameter of a log is always measured inside the bark. This measurement is called “diameter inside of bark” or d.i.b. Use a log scale stick to measure the d.i.b. at the small end of the log.
