Hotspots - Corne africaine (71) Images supplémentaires...
The Horn of Africa is one of only two entirely arid hotspots. It extends from Oman and Yemen through Eritrea and Somalia to parts of Ethiopia and Kenya. It is notable for endemic plants, with more than 2700 species. Both the frankincense and myrrh trees are native to this region. It is one of the most degraded of the world's hotspots, due to overgrazing and charcoal harvesting. Endemic mammals include the Hamadryas baboon, Speke's pectinator and 3 species of antelope.
