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:
“Thus all probable reasoning is nothing but a species of sensation. ‘Tis not solely in poetry and music, we must follow our taste and sentiment, but likewise in philosophy, When I am convinc’d of any principle, ‘tis only an idea which strikes more strongly upon me. When I give the preference to one set of arguments above another, I do nothing but decide from my feeling concerning the superiority of their influence.”
—David Hume (1711–1776)
“... 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)
