Species evenness is a measure of the relative abundance of the different species making up the richness of an area.
Explanation:
Evenness is the proportion of species or functional groups present on a site. The more equal species are in proportion to each other, the greater the evenness of the site. A site with low evenness indicates that a few species dominate the site.
If a community has a large disparity between the number of individuals within each species, it has low evenness. If the number of individuals within a species is fairly constant through out the community it has high evenness.
Evenness compares the similarity of the population size of each of species present.
