WebbSimpson’s Reciprocal Diversity Index 1 O.C.4- Analysis of the biodiversity of two local communities using Simpson’s reciprocal index of diversity. Background: Simpson’s index (D) is a measure of diversity, which takes into account both species richness, and an evenness of abundance among the species present. In WebbSimpson's Diversity Index is a measure of diversity which takes into account the number of species present, as well as the relative abundance of each species. As species richness and evenness increase, so diversity increases. n = the total number of organisms of a particular species N = the total number of organisms of ALL species
