Le Parc Urbain Bangr-Wéoogo : une aire de conservation de la diversité floristique au coeur de la ville de Ouagadougou, Burkina Faso

The results of 227 relevés taken in the urban park of Bangr-weoogo by applying the phytosociological ap- proach of Braun-Blanquet (1932) show that the park, consisting mainly of forest formations, still has an important species richness in spite of the high human pressure caused by more than 1 million habitants in the surroundings. The total number of species is 327 comprising 117 woody species and 210 herbaceous species. The flora forms 11 plant communities and is mostly constituted by phanerophytes and therophytes. The phytogeographical distribution of species shows that SoudanoZambesian and pantropical species are dominating.
