Basal area
Basal Area (pronounced: /ˈbeɪsəl ˈɛəriə/) is a term used in Forestry and Ecology to describe the area of a given section of land that is occupied by the cross-section of tree trunks and stems at their base. It is typically measured in square feet per acre or square meters per hectare.
Etymology
The term "Basal Area" is derived from the Latin word "basis" which means "base" and the Latin word "area" which means "a piece of level ground". In the context of forestry, it refers to the base of a tree trunk.
Measurement
The Basal Area of a forest stand is calculated by summing the cross-sectional area (at breast height, typically 1.3 meters above ground) of all trees in a given area. It is usually expressed in square meters per hectare or square feet per acre. The measurement is used in forestry to estimate the volume of timber in a stand and to describe the density of trees in an area.
