Taxonomic Diversity Calculator: Shannon-Wiener & Simpson Indices

Calculate Biodiversity Indices

Each line should contain the number of individuals for a single species.

Unravel ecosystem complexity with our Taxonomic Diversity Calculator. Easily compute species richness, Shannon-Wiener (H'), and Simpson's Index (D). Essential for ecologists, conservationists, and students studying biodiversity.

Formula:

Shannon-Wiener Index (H'): H' = - Σ (pi * ln(pi))
Where pi is the proportion of individuals of species i.

Simpson's Index (D): D = 1 - Σ (ni * (ni - 1)) / (N * (N - 1))
Where ni is the number of individuals of species i, and N is the total number of individuals in the sample.
