Floristic diversity of classified forest and partial faunal reserve of Comoé-Léraba, southwest Burkina Faso

: The classified forest and partial faunal reserve of Comoe-Leraba belongs to the South Sudanian phytogeographical sector of Burkina Faso and is located in the most humid area of the country. This study aims to present a detailed list of the Comoe-L e raba reserve’s flora for a better knowledge and conservation. Floristic inventories have permitted to record 540 plant species belonging to 342 genera and 91 families, thus representing 26.12% of Burkina Faso’s phytodiversity (2067 species). Fabaceae and Poaceae with 89 and 51 species respectively, were the dominant families. The vegetation is characterized by the dominance of both phanerophytes (45.51%) and therophytes (32.73%). The importance of Guineo–Congolian species proves that the Comoe-Leraba flora belongs to the Sudano–Guinean transition sector. Comoe-Leraba also accounts the highest number of exclusive species followed by the reserve of Sahel in the country. Exclusive species bring out its value in flora conservation.
