Abbreviation for tree diameter at breast height (4.5 feet above the ground).

The diameter of a tree outside of the bark at roughly breast height. Normally measured 4 V2 ft off the ground on the uphill side of the tree. It is easier to measure at this height, and many trees have large swells in the stem below this point that could increase errors in computing tree volumes.
