Definition of Species Evenness

Species evenness is an ecological term that is being defined as the measure of species abundance or relative species abundance that determines the richness of an area, landscape, or a particular region. If the species are present in proportion to each other in a specific site, then such a site is known as evenness.


Example of Species Evenness:

If there are 40 frogs and 44 wolves. When there is low evenness in a site, this shows that a few species are dominating the other species for example when there are 1000 dogs and 40 frogs. A high evenness in a site is important for biodiversity as well as for the stability of an ecosystem.
