Bioregion

A bioregion is an ecologically and geographically defined area that is smaller than a biogeographical realm, but larger than an ecoregion or an ecosystem, in the World Wildlife Fund classification scheme. There is also an attempt to use the term in a rank-less generalist sense, similar to the terms "biogeographic area" or "biogeographic unit".^[1]

It may be conceptually similar to an ecoprovince.^[2]

It is also differently used in the environmentalist context, being coined by Berg and Dasmann (1977).^[3]^[4]

WWF bioregions[]

The WWF scheme divides some of the biogeographic realms into bioregions, defined as "geographic clusters of ecoregions that may span several habitat types, but have strong biogeographic affinities, particularly at taxonomic levels higher than the species level (genus, family)." The WWF bioregions are as follows:^{[citation needed]}

Afrotropical realm^[5]
- Western Africa and Sahel
- Central Africa
- Eastern and Southern Africa
- Horn of Africa
- Madagascar–Indian Ocean
Antarctic realm
Australasian realm^[6]
- Australia
- New Guinea and Melanesia
- New Zealand
- Wallacea
Indomalayan realm^[6]
Nearctic realm^[7]
- Canadian Shield
- Eastern North America
- Northern Mexico and Southwestern North America
- Western North America
Neotropical realm^[8]
- Amazonia
- Caribbean
- Central America
- Central Andes
- Eastern South America
