Tree basal area. Tree Basal Area (TBA) is the cross-sectional area (over the bark) at breast height (1.3 metres above the ground) measured in metres squared (m2). TBA can be used to estimate tree volumes and stand competition.ree Basal Area (TBA) is the cross-sectional area (over the bark) at breast height (1.3 metres above the ground) measured in metres squared (m2).
Basal area is the area of a given section of land that is occupied by the cross-section of tree trunks and stems at the base. The term is used in forest management and forest ecology.o estimate a tree's basal area, use the tree's diameter at breast height in inches with the following formula: (Note: The factor of 144 is there to convert from Sq Inches to Sq Feet). This formula simplifies to: The result will be in ft 2.
