About one fifthof Southern Africa’s bird species migrate on aseasonal basis within Africa, and a further onetenth migrate annually between Africa and therest of the world (Hockey, 2000). One of themain intra-Africa migratory patterns are thoseof waterfowls which spend the austral summer inSouthern Africa and the winter in Central Africa.Analysis of the 2004 IUCN Red List showsthat the eastern, western and central subregionsof Africa have the highest number of threatenedplant and animal species (Fig. 6.6).Fig. 6.6: 2004 IUCN Red List of Threatened Species by Subregion in AfricanNumber of Species80070060050040030020010072 65 83 24163105 916611918412555830917611898213205 204 7880Northern Central Western Southern EasternSource: IUCN, 2004Mammals Birds Fishes Plants141
