This study was conducted around two experimental apiaries located in the Badenou protected forest, at the periphery and nearby the villages of Tiébila and Nafoun. Its purpose was to characterize the structure of woody vegetation and to evaluate its relative importance. For this purpose, a surface inventory was carried out in December 2017. The structure of the vegetation was studied through the density of woods, the basal area and the diameter structure. The relative importance of the flora was appreciated through the indices of importance value and rarefaction of species and families. An average floristic richness was observed with 96 species grouped into 72 genera and 30 families. The high density (1482 ± 657.15 stems/ha) and the average basal area (13.19±5.94 m2/ha) could be due to the good level of conservation of woodlands. The diametric structure of vegetation presented an appearance of "inverted J" and showed a predominance of small diameter trees. Eight species and eight families were predominant. Sixty-three species and 15 families were rare. Pending the results of the identification of honey plants, the woody flora studied is potentially melliferous. Its medium diversity and its high density were a major asset for beekeeping because they were likely to provide the floral resources necessary for a large production of honey.

Abstract: (french)
Cette étude a été conduite autour de deux ruchers expérimentaux installés dans la forêt classée de Badenou, en périphérie et à proximité des villages riverains de Tiébila et Nafoun. Elle a pour but de caractériser la structure de la végétation ligneuse et d’évaluer son importance relative. Pour cela, un inventaire de surface a été réalisé en décembre 2017. La structure de la végétation a été étudiée à travers la densité des ligneux, la surface terrière et la structure diamétrique. L’importance relative de la flore a été appréciée grâce aux Indices de Valeur d’Importance et de raréfaction des espèces et des familles. Une richesse floristique moyenne a été observée avec 96 espèces regroupées en 72 genres et 30 familles. La forte densité (1482 ± 657,15 tiges/ha) et la surface terrière moyenne (13,19 ± 5,94 m2/ha) seraient dues à un bon niveau de conservation des formations boisées de cette forêt. La structure diamétrique de la végétation présente une allure de « J inversé » et montre une prédominance des individus de petit diamètre. Huit espèces et huit familles sont prépondérantes. Soixante-trois espèces et 15 familles sont rares. En attendant les résultats de l’identification des plantes mellifères, la flore ligneuse étudiée est potentiellement mellifère. Sa diversité moyenne et sa forte densité constituent un atout majeur pour l’apiculture car elles sont susceptibles de fournir les ressources florales nécessaires pour une production importante de miel.
