WebbDiversity (or heterogeneity) includes both richness (the number of classes) and evenness (the distribution of individuals among classes). The most useful descriptions of diversity, therefore, present both measures of richness and evenness. Two commonly used measures Simpson's index D s and Shannon's index H'. WebbHerbaceous plant diversity in two forest patches is sampled. In the first patch, you find 4 species of equal abundance (2 individuals per species).
