How to Use This Calculator
- Enter the Average DBH in inches, the Tree Count from your sample plot, and the Plot Size in acres.
- Review Trees Per Acre and Basal Area Per Acre as the primary stocking indicators.
- Check Stand Density Index (SDI) and Stocking Percentage to assess crowding relative to maximum density.
- Use Crown Competition Factor (CCF) to determine if the stand needs thinning to reduce competition.
- Review Average Tree Spacing to plan silvicultural treatments and access for equipment.
