Difference between species evenness and species richness

Species evenness refers to how close in numbers each species in an environment is
(So if there are 40 foxes, and 1000 dogs, the community is not very even.)

Species richness is the number of different species represented in an ecological community, landscape or region. 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.

species richness is related to species diversity 

species evenness refers to how close in numbers each species in an environment are.
