User Guidelines
To use the Forest Productivity Calculator effectively, follow these steps:
- Count Trees: Determine the number of trees per hectare in the forest stand.
- Measure DBH: Measure the average diameter at breast height (1.3 m above ground) in centimeters using calipers.
- Measure Height: Record the average tree height in meters using a clinometer or laser rangefinder.
- Select Species: Choose the tree species to apply the appropriate form factor.
- Calculate: Click the “Calculate Forest Productivity” button to obtain the estimated timber volume in cubic meters per hectare.
Ensure measurements are accurate and taken from representative plots. For more on forest yield, refer to Forest Productivity.

Purpose of the Forest Productivity Calculator
The primary purpose of the Forest Productivity Calculator is to offer a user-friendly, scientifically accurate tool for estimating forest timber yield per hectare. It uses simplified volume equations based on tree measurements and species-specific form factors, delivering reliable results for forest managers, researchers, and landowners. The tool supports sustainable forestry practices, aligning with industry standards for yield estimation, and facilitates applications in timber production, carbon accounting, and ecological studies, ensuring efficient and informed forest management.
Scientific Basis of the Calculator
The Forest Productivity Calculator is grounded in forest mensuration principles, using a simplified volume equation:
Volume (m³/ha) = Number of Trees × Basal Area × Height × Form Factor
- Number of Trees: Trees per hectare.
- Basal Area: Calculated as π × (DBH/200)² (DBH in cm).
- Height: Average tree height in meters.
- Form Factor: Species-specific adjustment (e.g., 0.5 for pine, 0.6 for oak).
This formula, derived from standard forestry models, accounts for tree geometry and stand density, validated by sources like the USDA Forest Service and the Forest Productivity Cooperative. The calculator assumes even-aged, single-species stands for simplicity, aligning with common yield table methodologies.
