Ecosystem diversity is one of the three levels of biodiversity and refers to the variety of habitats and ecosystems present in a region.

Ecosystem diversity refers to the variety of habitats and ecosystems, such as forests, deserts, wetlands, and coral reefs.

Genetic variation belongs to genetic diversity, whereas ecosystem diversity includes different ecosystems such as deserts, rainforests, wetlands, and coral reefs.

Evenness measures how uniformly individuals are distributed among the species present. Two communities may contain the same number of species yet differ greatly in diversity if one is dominated by a single species while the other has comparable abundances throughout. Richness counts species without considering their relative numbers, whereas dominance emphasizes concentration in one or a few taxa. Turnover instead describes compositional change across places or times. Thus abundance differences are captured specifically by evenness, an essential component of indices such as Shannon diversity.

An ecotone is the transition zone between two neighbouring ecosystems or communities. Because environmental conditions and resources overlap, it can contain species from both adjoining systems as well as edge specialists that occur mainly in the transition. This combination can produce the edge effect—locally elevated richness, abundance, or interaction intensity. Examples include a forest–grassland margin, an estuary between river and sea, or a marsh–upland boundary. Elevated diversity is not inevitable: abrupt human-created edges may exclude interior specialists, increase predation or invasi
