Ecozone

From Academic Kids

A biogeographical realm or ecozone is a biogeographical and ecological land classification system of the world first formally proposed by Miklos Udvardy in 1975 for conservation purposes. Arguably, biomes are better suited for conservational purposes.

8 biogeographical realms with unifying features of geography, fauna and flora are defined.

Udvardy originally further divided the biogeographic realms into 203 biogeographical provinces (floral "regions" and faunal "provinces").

Intensive regional analyses of biodiversity patterns across five continents and biogeographical realms have been used by the World Wildlife Fund to defined the boundaries of terrestrial ecoregions for the Global 200.

The biogeographic realms are also supporting current natural World Heritage sites.
