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:
“Prohibition will work great injury to the cause of temperance. It is a species of intemperance within itself, for it goes beyond the bounds of reason in that it attempts to control a man’s appetite by legislation, and makes a crime out of things that are not crimes. A Prohibition law strikes a blow at the very principles upon which our government was founded.”
—Abraham Lincoln (1809–1865)
“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)
