WebGingrich™s stocking guides (below) are used to determine whether existing stands have (1) sufficient basal area in growing stock trees to carry through rotation, or (2) whether the stands should be regenerated. The C level of stocking is used as a minimum of basal area required to carry existing stands. 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 you cut down all the merchantable trees on an acre at 4 ½ feet off the ground and measured the square inches on the top of each stump (πr*r), added them all together and divided by square feet (144 sq inches pe…
