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)
“Down to the Puritan marrow of my bones
There’s something in this richness that I hate.
I love the look, austere, immaculate,
Of landscapes drawn in pearly monotones.”
—Elinor Wylie (1885–1928)
