Calculation Formula

Basal Area (BA) = π * (Girth/2)^2 / 43560

Where:
π = Pi (approximately 3.14159)
Girth = Total girth of the tree in inches
43560 = Number of square feet in an acre

Understanding Basal Area

Basal area is a measure of the cross-sectional area of trees at breast height (typically 4.5 feet above ground level). It is used in forestry to estimate the amount of timber in a stand of trees. The basal area per acre is a key factor in determining the productivity of a forest and is used in various management decisions.

Formula Explanation

The formula used to calculate the basal area per acre is:

Basal Area (BA) = π * (Girth/2)^2 / 43560

This formula calculates the cross-sectional area of a single tree and then converts it to an area per acre by dividing by the number of square feet in an acre (43560).
