The Basal Area Calculator calculates the basal area per acre of a forest based on the Diameter at Breast Height (DBH) of trees and the Number of Trees per Acre.

Basal area is a key measure in forestry that indicates the density of a forest, providing valuable insights for forest management, biodiversity, and timber assessment.

**How to use the Calculator:**

- Enter the
**Diameter at Breast Height (DBH)** in inches.
- Enter the
**Number of Trees per Acre**.
- Click

**Solved Calculations**

**Example 1**

**Step** |
**Calculation** |

**DBH** |
12 in |

**Trees per Acre** |
100 |

**Basal Area per Acre** |
(to be calculated) |

**Calculation** |
0.005454 × 12² × 100 = **78.13 ft²** |

In this example, with a DBH of 12 inches and 100 trees per acre, the basal area per acre is calculated as 78.13 square feet.

**Example 2**

**Step** |
**Calculation** |

**DBH** |
15 in |

**Trees per Acre** |
80 |

**Basal Area per Acre** |
(to be calculated) |

**Calculation** |
0.005454 × 15² × 80 = **98.19 ft²** |

For a forest with an average DBH of 15 inches and 80 trees per acre, the basal area per acre is 98.19 square feet, reflecting the density of trees within that area.
