Definition of Species Richness
Species richness is an ecological term that is defined as the number of various species that are coexisting in a certain ecological community (different populations form a community), region, or landscape. In species richness, the distribution and relative abundances of different species are not taken into account.
It just helps in measuring the total count of species. It is measured by dividing the number of species by the square root of the number of individuals present in the sample. The main purpose of studying this is to determine and assess the protection and conservation values of different habitats and landscapes. The identification of species is not done in this.
