Detailed explanation-1: -The basal area formula for a single tree uses the foresters constant, which is a number used to convert square inches (dbH is measured in inches) into square feet (the basal area is measured in square feet). This number is 0.005454, and is equal to 4∗144 4 ∗ 144 .
Detailed explanation-2: -Basal Area, Do the Math 0.005454 is called the “foresters constant", which converts inches into square feet. The basal area of a 10-inch tree is: 0.005454 x (10)2 = 0.5454 square feet (ft2). So, 100 of these trees per acre would calculate out a BA of 54 ft2. or a count of just over 5 trees per angle gauge count.
Detailed explanation-3: -BA is measured by adding the area of the stems at breast height of all the trees in the stand. Because of the time required to measure every tree, only a sample of the stand is measured. The sample is used to predict the total amount of basal area in the stand.
