Dbh tape units
WebDiameter at breast height (DBH) is measured by holding the stick a fixed distance, usually 25 inches (64 cm), from the eye, and at breast height, which in the United States is 4.5 feet (1.4 m) up the bole of the tree. The left side of the stick is flush with the left side of the tree. WebOct 9, 2024 · The only thing you have to do to tape it around the tree at DBH is to make sure you know how many times the tape meets the number. It is sufficient to determine the diameter of the tree in this case. A tree’s DBH, or circumference multiplied by its average growth ring width, is calculated by North Carolina State University.
