DBH

Means “diameter breast-high”;the diameter of a tree at a point 41/2 feet above the ground.

Many homeowners associations prohibit cutting trees of a certain DBH on one's own land, unless the property owner receives prior approval.

When selling timber, purchasers generally need to know the average DBH for the trees. The information is also necessary to calculate tonnage of timber, which is the more modern way of pricing, rather than calculating board-feet.

From the data I compiled floristic tables of family, genus and species and then generated these physical structure parameters (1) the total number of stems, the mean dbh among those stems, and the number of stems in each of four size classes: 10 cm < 20 cm dbh, 20 cm < 30 cm dbh, 30 cm < 40 cm dbh and those with a dbh [greater than or equal to] 40 cm, (2) the total basal area which is the sum of the basal areas of all individual stems ([SIGMA][pi][r.sup.2]; where r = the dbh of the individual stem / 2), (3) the aboveground (AG) biomass of all the trees (using the formula in Nascimento and Lawrance [2002] suggested for tropical trees of these stem sizes), (4) the percent closure of the canopy (using the formula in Buchholz et al.
