Species richness

Species richness is the number of different species represented in an ecological community, landscape or region.^[1] 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 sometimes considered synonymous with species diversity, but the formal metric species diversity takes into account both species richness and species evenness. Species richness has proven to be a positive representation to show how species interaction in ecosystems can lead to the productivity and growth of biodiversity. ^[2]
