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:
“For my own part I think no innocent species of wit or pleasantry should be suppressed: and that a good pun may be admitted among the smaller excellencies of lively conversation.”
—James Boswell (1740–1795)
“Language fails not because thought fails, but because no verbal symbols can do justice to the fullness and richness of thought. If we are to continue talking about “data” in any other sense than as reflective distinctions, the original datum is always such a qualitative whole.”
—John Dewey (1859–1952)
