Magnoliophyta, Biosphere Reserve of Pendjari, Atacora province, Benin

The Biosphere Reserve of Pendjari is an example of best management practice of protected areas in West Africa with typical Sudanian savanna vegetation. It is part of the vast and transboundary protected areas of W, Pendjari and Arly National Parks of Benin, Burkina Faso and Niger. This work provides an overview of the flora of the reserve by means of a thorough botanical inventory. The plant species composition is typical of Sudanian savanna. We recorded 684 plant species, which were distributed among 366 genera and 89 families. The two most species-rich families were Fabaceae (115) and Poaceae (112). The most important life forms were phanerophytes and therophytes. The chorological spectrum was dominated by Sudanian species. With Ipomoea beninensis Akoègninou, Lisowski and Sinsin, Thunbergia atacorensis Akoègninou and Lisowski and Cissus kouandeensis A.Chev., three endemic species of Benin were recorded, demonstrating the importance of the reserve for plant conservation.
