Why Measuring Forest Biodiversity Matters
Biodiversity is the foundation of resilient, healthy forests. High-diversity stands resist pests, store more carbon, and support wildlife. This calculator combines species richness, structural complexity, deadwood, and nativeness into a single, easy-to-understand index used in FSC certification, REDD+, and national forest monitoring.
How to Use the Calculator
- Enter number of tree species and total trees from your plot inventory
- Input deadwood volume (m³/ha) and vertical layers (1–5)
- Enter percentage of native species
Scientific Formula (Adapted from FOBI & Shannon-Wiener)
FBI = (Shannon H' × 0.4) + (Deadwood × 0.2) + (Structure × 0.2) + (Native% × 0.2)
Applications
- Forest management planning
- Carbon + biodiversity credit projects
- FSC & PEFC certification
- Conservation impact reporting
Conclusion
Get instant, science-backed biodiversity scores — completely free and trusted by foresters worldwide.
