| | Udvardy Biogeographical Provinces (Life Zones) of Africa |
 | | This classification of biogeographical zones was proposed by Dr. Miklos Udvardy in his paper for IUCN and UNESCO in 1975, with intended use as a unified system for biogeographical and conservation purposes. |
 | | Biogeographical realms were established by Udvardy on the basis of geographic and historic elements, utilizing ground-breaking work as appears on this topic in the published literature. |
 | | There are 8 biogeographical realms recognized by Udvardy in Paper #18: the Palearctic, the Nearctic, the Afrotropical, the Indomalayan, the Oceanian, the Australian, the Antarctic and the Neotropical. |
