The Aghien estate, the site of this study, is part of the dynamic of creating a new peri-urban nature reserve. Following the regression of the surface areas of protected areas by human activities within the Ivorian parks and reserves, the partial Aghien nature reserve was created to allow the survival of this particular ecosystem, essential for the preservation of the peri-urban forest and the conservation of biological diversity. The general objective of this study is to assess the floristic diversity of the Partial Nature Reserve of Aghien. To do this, 36 plots of 625m2 (25 m x 25 m) each were first distributed in six (06) biotopes of the partial nature reserve of Aghien (RNPA). These are rubber plantation (n = 6) palm plantation (n = 6), secondary forest (n = 6), swamp meadow (n = 6), fallow land (n = 6), Bare soil (n = 6). Then botanical inventories based on itinerant and surface survey methods were carried out in each plot. A total of 265 species divided into 174 genera and 63 families were inventoried in the RNPA. Finally, the assessment of the floristic composition of the vegetation and that of the floristic composition of the vegetation were determined by the floristic variability and the diversity indices.

The aim of this study is to map land use and analyse the dynamics of landscape structure through the spatial transformation processes that took place between 1987 and 2017. The analysis, using remote sensing, spatial indices and spatial transformation processes, showed a heterogeneous landscape associated with an increase in the extent of human activity over the period studied. The classes have undergone a number of spatial transformations, the most striking of which are dissection and fragmentation for natural formations and creation for artificial formations. These processes are linked to the combined effect of human activities and the natural dynamics of the region’s plant formations.
