WebbAnother widely used index of diversity that also considers both species richness and evenness is the Shannon-Weiner Diversity Index, originally proposed by Claude Shannon … WebbIt is important to distinguish ‘richness’ from ‘diversity’. Diversity usually implies a measure of both species number and ‘equitability’ (or ‘ evenness ’). Three types of indices can be distinguished: 1. Species richness indices: Species richness is a measure for the total number of the species in a community (examples Fig. 1a).
