On a per tree basis, basal area is the surface area in square feet of the cross section of the tree bole at breast height. On a per acre basis, it expresses the total basal area for all trees within that acre. It is an efficient and logical measurement of stand density and is the basis for many silvicultural prescriptions and forest management activities.
Singular: Board foot; Plural: Board feet
A board foot is a lumber measurement equal to a board or plank of wood 1 inch thick and 12 inches on each side. The formula for calculating board feet of sawed lumber is
bd ft = thickness(in) x width(in) x length(ft)/12. For example, a board that is 1 inch thick, 12 inches wide, and 10 feet long contains 10 board feet of lumber(1x12x10/12=10).
Also known as "Board feet of lumber".
