Detailed explanation-1: -1. A diameter tape, or d-tape, is the most common tool. The tape is wrapped around the tree, measuring its circumference. The tape is graduated to reflect a conversion from tree circumference to tree diameter.
Detailed explanation-2: -Tree diameter is usually measured at 4.5 feet (ft) above ground level. Measurement at this height is referred to as diameter at breast height or DBH. DBH can be measured with a specially calibrated tape measure called a diameter tape (d-tape) available from most arborist or forestry supply dealers.
Detailed explanation-3: -Diameter Tape. A diameter tape (D-tape) is used by foresters to measure the diameter of a tree. Since trees are swelled at the base, measurements are made 4.5 feet above the ground in order to give an average diameter estimate.
