How do you find a species number?
Divide Shannon’s diversity index H by natural logarithm of species richness ln(S) to calculate the species evenness. In the example, 0.707 divided by 1.099 equals 0.64. Note that species evenness ranges from zero to one, with zero signifying no evenness and one, a complete evenness.
