Safeopedia explains Species Diversity

Species diversity as compared to benchmarks can be used to evaluate the health of ecosystems. In a healthy ecosystem, the species that would ordinarily occupy various niches in an untouched, benchmark site would be present in similar richness, abundance and evenness. Species diversity measurements can be used to determine the need for conservation interventions and a high level of species richness may indicate the presence of rare species or species that are unique to an ecosystem.
