Analysis of the Effects of Anthropogenic Activities on the Biodiversity of the Monts Nimba Biosphere Reserve, Republic of Guinea

This work focuses on the study of the impacts of anthropogenic activities on the forest ecosystem of the Monts Nimba-Préfecture Lola Biosphere Reserve. For data collection, the kobocollect tool was used through a questionnaire developed for this purpose and sent to resource people. The general objective of this study is to assess the impact of anthropogenic activities on the forest ecosystem of the reserve. Thus, Word, Excel and kobocollect software were used for data processing. The results we reached show us that agriculture, practiced by 48% of respondents, hunting 9%, forestry (logging and pharmacopoeia) 25%, livestock breeding 10% and fishing 8% are listed socio-economic activities having harmful consequences on vegetation, fauna, soil and watercourses. Khaya ivorensis, Triplochiton, Scloroxylon, Terminalia suprba, Clorophora excelsa, Albizzia zygia, Terminalia ivoiriensis, Ceiba pentandra are species used especially in timber exploitation. In addition, Khaya senegalensis, Fagara macrophyla, Garcinia cola and bombax costantum are the species used in the pharmacopoeia. Depending on the degree of impact, agriculture and logging are activities with a major effect on biodiversity (flora and soil). However, livestock farming, fishing and hunting are activities with a medium effect, whereas trade remains the activity with a low effect.
