Calculation method
Calculation method
Species plant orders
ceil(area×approved density/survival); summed by species.
Total ordered plants
Sum rounded-up requirements; survival fractions are supplied assumptions.
Symbols and units

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Target patches, approved densities, survival assumptions. Returns Plants by species and replacement reserve. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification.
