Species richness is the number of different species represented in a set or collection of individuals. Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions. In contrast, species diversity takes into account both species richness & species evenness.

Famous quotes containing the words species and/or richness:
“If there is a species which is more maltreated than children, then it must be their toys, which they handle in an incredibly off-hand manner.... Toys are thus the end point in that long chain in which all the conditions of despotic high-handedness are in play which enchain beings one to another, from one species to another—cruel divinities to their sacrificial victims, from masters to slaves, from adults to children, and from children to their objects.”
—Jean Baudrillard (b. 1929)
“... the selfishness that is bred of great success is our shame. We have subdued the wilderness and made it ours. We have conquered the earth and the richness thereof. We have indelibly stamped upon its face the seal of our dominating will. Now, unlike Alexander sighing for more worlds to conquer, we should address ourselves to adding beauty to that glory and grandeur.”
—Alice Foote MacDougall (1867–1945)
