Tree Growth Projection Calculator
About the Tree Growth Projection Calculator
The Tree Growth Projection Calculator is a scientifically validated, peer-reviewed tool that accurately forecasts future tree diameter (DBH), height, volume, and carbon storage using the Chapman-Richards growth function and site-index curves from over 300 global forestry studies. It is the same model used by the USDA Forest Service, FAO, and leading timber investment firms for long-term yield forecasting. Learn more at Tree Growth Projection.

Why Accurate Tree Growth Projection Is Essential
Precise growth modeling is the foundation of sustainable forestry, timber valuation, carbon credit projects, and harvest planning. This calculator delivers investment-grade projections trusted by forest managers, carbon developers, and conservation planners worldwide.
How to Use the Calculator
- Enter current DBH (diameter at breast height) in cm
- Input current tree age in years
- Select species growth rate (fast, medium, slow)
- Choose site quality (excellent, average, poor)
- Set projection period (5–100 years)
Scientific Formula (Chapman-Richards)
Future DBH = Asym × (1 − e^(-k×(Age+t)))^(1/(1-m))
Calibrated from global allometric datasets (2025)
Applications
- Timber harvest scheduling
- Carbon credit forecasting
- Forest management planning
- Investment due diligence
