The impact of debarking, a common practice in Parakou, is little known to the general public. This study, which focused on khaya senegalensis, Parkia biglobosa and vitellaria paradoxa, aims to determine the impacts of debarking on biodiversity in the municipality of Parakou in 2019. The methodological approach was based on the documentary research, interviews, ethnobotanical surveys, floristic and dendrometric surveys, data processing and analysis of results. The non-probability sample with exhaustive recruitment of the different types of actors in the study area consists of 116 people. The floristic and dendrometric surveys were made through six (06) 900 m² (30 × 30) plots installed in the reforestation area of Parakou. A total of 17 species belonging to 17 genera grouped into 7 Families are listed. The Parkia biglobosa is 36% the most exploited species in the town followed by khaya senegalensis (33%) and vitellaria paradoxa at 31%. The barks (45.43%) and the leaves (29.83%) are the most used organs (seven (07) categories of use). The scarcely diversified perimeter has experienced significant deterioration. Destruction of habitats, reduction of species, vulnerability to bad weather and attack by pests, are among the impacts of debarking on biodiversity. Knowledge of the processes and factors that govern the regeneration of these species is one of the perspectives to be taken into account in terms of their protection and conservation.

Abstract
The impact of debarking, a common practice in Parakou, is little known to the general public. This study, which focused on khaya senegalensis, Parkia biglobosa and vitellaria paradoxa, aims to determine the impacts of debarking on biodiversity in the municipality of Parakou in 2019. The methodological approach was based on the documentary research, interviews, ethnobotanical surveys, floristic and dendrometric surveys, data processing and analysis of results. The non-probability sample with exhaustive recruitment of the different types of actors in the study area consists of 116 people. The floristic and dendrometric surveys were made through six (06) 900 m² (30 × 30) plots installed in the reforestation area of Parakou. A total of 17 species belonging to 17 genera grouped into 7 Families are listed. The Parkia biglobosa is 36% the most exploited species in the town followed by khaya senegalensis (33%) and vitellaria paradoxa at 31%.

Abstract: (french)
Les impacts de l’écorçage, une pratique courante à Parakou, sont peu connus du grand public. Cette étude qui s’est portée particulièrement sur le khaya senegalensis, le Parkia biglobosa et le vitellaria paradoxa, vise à déterminer les impacts de l’écorçage sur la biodiversité dans la commune de Parakou en 2019. La démarche méthodologique s’est appuyée sur la recherche documentaire, les entretiens, les enquêtes ethnobotaniques, les relevés floristiques et dendrométriques, le traitement des données et l’analyse des résultats. L’échantillon non probabiliste avec recrutement exhaustif des différents types d’acteurs de la zone d’étude est constitué de 116 personnes. Les relevés floristiques et dendrométriques ont été faits à travers six (06) placettes de 900 m² (30×30) installés dans le périmètre de reboisement de Parakou. Au total 17 espèces appartenant à 17 genres regroupés en 7 Familles sont recensées. Le Parkia biglobosa est à 36 % l’essence la plus exploitée dans la commune suivit du khaya senegalensis (33 %) et du vitellaria paradoxa à 31 %. Les écorces (45,43%) et les feuilles (29,83%) sont les organes les plus utilisés (sept (07) catégories d’usage). Le périmètre très peu diversifié, a connue d’importante dégradation. La destruction des habitats, la réduction des espèces, la vulnérabilité aux intempéries et aux attaques des parasites, sont entre autres des impacts de l’écorçage sur la biodiversité. La connaissance des processus et facteurs qui régissent la régénérescence de ces espèces est l’une des perspectives à prendre en compte en matière de leur protection et de leur conservation.
