Basal Area Calculator

Formula

The formula to calculate the Basal Area (BA) is:

$BA = F \cdot DBH^2 \cdot N$

Where:

$BA$ is the Basal Area
$F$ is the Forester's Constant (0.005454)
$DBH$ is the Average Diameter at Breast Height (inches)
$N$ is the Number of Trees per Acre

Basal Area Definition

Basal area is defined as the total area of an acre that is occupied by tree stems. It is a crucial measurement in forestry, used to estimate the density and productivity of a forest.

Example Calculation

Let's consider an example:

Average Diameter at Breast Height (DBH): 10 inches
Number of Trees per Acre (N): 100

Using the formula to calculate the Basal Area:

$BA = 0.005454 \cdot 10^2 \cdot 100 \approx 54.54 \, \text{square feet per acre}$

This demonstrates that with a DBH of 10 inches and 100 trees per acre, the basal area would be approximately 54.54 square feet per acre.
