WebbSimpson’s Diversity Index (D) is a measure of the relationship between the number of different species in a habitat ( species richness) and the number of individuals within … WebbThe value of Simpson’s D ranges from 0 to 1, with 0 representing infinite diversity and 1 representing no diversity, so the larger the value of D, the lower the diversity. For this reason, Simpson’s index is usually expressed as its inverse (1/D) or its compliment (1-D) which is also known as the Gini-Simpson index. Let’s look at an example.
