Basal area is the cross-sectional area of trees at breast height (1.3m or 4.5 ft above ground). It is a common way to describe stand density. In forest management, basal area usually refers to merchantable timber and is given on a per hectare or per acre basis. If one cut down all the merchantable trees on an acre at 4.5 feet (1.4 m) off the ...
When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
Basal area – defines the area of a given section of land that is occupied by the cross-section of tree trunks and stems at their base; Diameter at breast height (DBH) – measurement of a tree's girth standardized with different countries having different standards they are often at 1.3 meters (about 4.5 feet) above the ground
Each mapped trunk and branch was measured for basal diameter, length, azimuth, Climbers measure specific circumferences and detail other features within the tree. In addition a footprint map of the base of the tree is made to calculate the exact volume of the basal section of the tree. The data is processed in Excel to generate a volume ...
If it does then the tree is IN. If it doesn't then the tree is OUT (Figure 1). If the tree is IN this means that it is counted as basal area within one's plot. The basal area is obtained by multiplying the number of trees by the basal area factor, which is based on the width of the gauge. [2]
