Q

Species richness can be a misleading indicator of diversity as it does not take into account the

A

number of individuals of each species

For example, habitat A has 10 different plant species and habitat B has 7 different plant species

Habitat A would be described as being more species-rich than habitat B

However, in habitat A there is only one individual of each plant species present (10 individuals present) while in habitat B there are over 20 individuals of each species present (over 140 individuals present)

This example illustrates the limitations of species richness
