In Côte d’Ivoire, the problem of forest sustainability has led to studies on their dynamics being undertaken in recent years. The Dahliafleur Nature Reserve, located in the commune of Bingerville is part of the Ivorian urban forests. Unfortunately, it is very little known in its floristic diversity, let alone its vegetation. The surface surveys supplemented by the mobile survey made it possible to identify 135 species throughout the forest. These species are divided into 110 genera and 53 families. The most represented families in these three zones are respectively for the North, South and East zones, the Fabaceae, the Apocynaceae and the Araceae. The analysis of the chorological spectrum of all the species identified highlights five types of chorological affinities. The species with the strongest I.V.I. are (in descending order) Tabernaemontana crassa, Ceiba pentandra, Senna siamea, Acacia mangium, and Nesogordonia papaverifera. A comparison of the different plots in two by two reveals a rather weak similarity.

The main objective of this study was to contribute, on the one hand, to the understanding of the concept of a biosphere reserve, on the other hand, to take stock of the experience of the Taï Biosphere Reserve in this area. According to the recommendations of the UNESCO MAB Program, a biosphere reserve has to comprise three zones, 1) a central monitoring area, 2) a buffer zone for research, experimentation, education, tourism and recreation, and 3) a transition area for research, tourism, recreation as well as local and sustainable development. This study shows that the Taï Biosphere Reserve is structured in three areas, which corresponds to the functions mentioned above. It is remarkable that the managers of what? have been able to adapt the zoning to the local realities. In particular, they took the objectives of sustainable conservation of the biodiversity and the sustainable development activities of the local populations into account. However, more capacity strengthening is needed, and relations between the Taï Biosphere Reserve and the surrounding forests should be improved. Although the different functions are operational, they should be further developed, particularly tourism and scientific research.
