Abstract:
The Comoé National Park is an area of extreme vegetation complexity, with an unpredictable
mosaic of several vegetation types ranging from very open savannahs to closed forests. This
complexity, linked to the park's position between the sub-Sudanese and Sudanese sectors, gives
it a great wealth of flora. However, unlike the Sub-Sudanese sector, the Sudanese part has not
been studied much. This study aims to contribute to a better knowledge of the flora of the
Sudanese sector of Comoé National Park. To do this, phytosociological surveys were carried out
using the Braun-Blanquet method in 210 plots of 900 m2 in the different plant formations. This
made it possible to identify 546 species, divided into 326 genera belonging to 76 families.
Among these species, 20 were inventoried for the first time in the Sudanese sector. The most
abundant families are Fabaceae (24%), Poaceae (20%), Cyperaceae (17%) and Rubiaceae (11%).
In addition, Phanerophytes dominate (52,26%) and a high proportion of species common to the
Guinean-Congolese and Sudano-Zambézian regions (62,41%). This reflects a physiognomic
change in the vegetation of the Sudanese sector of Comoé National Park. |
