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).
Basal Area is the cross-sectional area of trees stem (trunk) at breast height. For individual trees, basal area is expressed as in square meters (i.e. 0.25mÂ²). When estimating the average basal area of a forest stand it is generally reported as mÂ² per hectare (i.e. 35m2/hectare).The basal area of a forest can be measured directly using a dbh tape or estimated by using a wedge prism.or individual trees, basal area is expressed as in square meters (i.e. 0.25mÂ²).
