For example, if you weigh 200 pounds, a 5 percent weight loss equals 10 pounds, bringing your weight down to 190 pounds. While this weight may still be in the overweight or obese range, this modest weight loss can decrease your risk factors for chronic diseases related to obesity.
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).
represents) for plot trees by taking the denominator of the plot size (e.g. 20 for a 1/20th acre plot) and dividing by the number of plots. For each plot tree, determine the basal area (in square feet) by multiplying the DBH (in inches) by itself (i.e. square it) and then multiplying by 0.005454: Tree BA = .005454 x DBH2 2. Multiply the basal area for each tree by the expansion factor to determine the basal area per acre represented by each tree.
