Natural and anthropogenic disturbances affect forest integrity and floristic composition. The resulting secondary habitats is characterised by liana and herb species which modified the forest physiognomy. To elucidate the floristic characteristics of these secondary forests, the present study was carried out after logging operations in the the Haut-Sassandra protected Forest. The inventory has been realised in 18 individual one ha in three level of logging operation. A total of 445 species have been identified. Floristics parameters vary according to the time after logging operation: from 255 in the south sector, 296 species in the center sector, 271 species in the north sector, 15 years after logging. The family diversity is between 56 and 62 with a predominance of Rubiaceae. Phytogeographic-types are characterized by Guinean-Congolese species (71,2 %), and species endemic to SavannahForest transition zone (14,6 %). The presence of herb and liana species which are pioneer and heliophile, could generate a micro climate favorable to the recovery of other forest plant species.Keywords: Forest resilience, forest logging, ecological temperament, floristic gradient, Côte d'Ivoire RésuméDes perturbations tant naturelles qu'anthropiques, affectent l'intégrité des forêts et leur composition floristique.

Pour caractériser la flore herbacée et lianescente de telles végétations secondaires, la présente étude a été réalisée dans la Forêt Classée du Haut-Sassandra après des activités d'exploitations forestières. L'inventaire a été réalisé dans 18 parcelles de un ha chacune et placées dans trois secteurs de niveau d'exploitation différente. Au total, 445 espèces y ont été recensées. Les résultats montrent une variation des paramètres floristiques en fonction du secteur d'exploitation: 255 espèces dans le secteur Sud, 296 espèces dans le secteur Centre, 271 espèces dans le secteur Nord, 15 ans après les exploitations. La diversité des familles est comprise entre 56 et 62 avec une prédominance des Rubiaceae. Les types phytogéographiques sont caractérisés par des espèces à distribution Guinéo-Congolaise (71,2 %) et des espèces de la zone de transition Savane-forêt (14,6 %). La présence de cette flore herbacée et lianescente, souvent pionnière et héliophile, génère un microclimat qui pourrait être favorable à la germination d'autres semences forestières.
Objective: To identify the anti-hemorrhoidal medicinal plants of the Department of Issia and evaluate the cytotoxic activity of the most requested species. Methods: The plants used in hemorrhoid recipes in the Department of Issia (Côte d'Ivoire) were obtained using a semi-structured survey based on a questionnaire sheet. To assess the use of plants on the disease, Informant Consensus Factors (ICF) for each species were calculated. The harvested species were identified at the Centre National de Floristique (CNF) of the Félix Houphouët Boigny University (Côte d'Ivoire). Cytotoxicity tests were performed on HFF cells with the 70% ethanolic extract, prepared from the aqueous extract of the most cited species. Results: A total of twenty four medicinal species in eighteen families were recorded. Among these taxa are ten woody and fourteen herbaceous. Only three species gave an ICF greater than 0.5. The ethanolic extract 70% of the frequently requested medicinal plant did not reveal any toxicity on HFF cells. Conclusion: These results revealed that the flora of the Department of Issia is rich in anti-hemorrhoidal medicinal plant species. Their use without side effects is revealed by the absence of toxicity in one of the most solicited plants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
