Webb29 mars 2024 · The value for Simpson’s Diversity Index ranges between 0 and 1. The higher the value, the lower the diversity. Since this interpretation is a bit counterintuitive, we often calculate Simpson’s Index of Diversity (sometimes called a Dominance Index), which is calculated as 1 – D. WebbThe following example demonstrates the range of Shannon Evenness and Richness. and the Evenness = 1. If that same 40 pixel area has two land cover classes and one class is represented in only 1 pixel then the Richness = 2 and the Evenness = 0.1687. More information on the Shannon Diversity: Richness and Evenness can be found on the …
