This tutorial covers three key diversity metrics: + +### Shannon Diversity Index (H') +The Shannon diversity index (Shannon, 1948) measures both species richness and evenness: + +**H' = -Σ(pi × ln(pi))** + +Where pi is the proportion of species i. Higher values indicate greater diversity. +- Values typically range from 0 to 5 +- H' = 0 indicates a monoculture +- H' > 3 indicates high diversity + +### Simpson Diversity Index +The Simpson index (Simpson, 1949) has multiple formulations: + +**Simpson's Dominance (D)**: Σ(pi²) +- Probability that two individuals belong to the same species +- Values range from 0 to 1 (lower = more diverse) + +**Simpson's Diversity (1-D)**: 1 - Σ(pi²) +- Probability that two individuals belong to different species +- Values range from 0 to 1 (higher = more diverse) + +**Inverse Simpson (1/D)**: 1/Σ(pi²) +- Effective number of equally abundant species +- Values range from 1 to S (number of species) + +Note: The BigMap implementation calculates dominance (D) by default, with options for diversity (1-D) or inverse (1/D) via the `inverse` parameter. + +### Pielou's Evenness (J) +Pielou's evenness (Pielou, 1966) measures how evenly species are distributed: + +**J = H' / ln(S)** + +Where S is the number of species. +- Values range from 0 to 1 +- J = 1 indicates perfect evenness +- J < 0.5 suggests dominance by few species + +### When to Use Each Index +- **Shannon**: General biodiversity assessment, sensitive to rare species +- **Simpson**: When dominance patterns are important +- **Species Richness**: Simple count when presence/absence is sufficient +- **Evenness**: To assess community balance independent of richness + +## Overview + +We'll analyze forest species diversity across North Carolina by: +1.
