FLORISTIC AND PHYSIOGNOMY CHARACTERISTICS OF THE VEGETATION FROM THE SUDANESE SECTOR OF COMOÉ NATIONAL PARK (NORTH-EAST OF CÔTE D'IVOIRE)

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.
