This work that is one of the first of its kind in Unburned Savannah in Lamto, center of Ivory Coast, intends to characterize the vegetation in terms of dynamic evolution and plant structure, 53 years after its protection from fires. Surfaces plot, linear surveys and itinerant methods were used to collect floristic data. The diversity and the wealth of flora, as well as the structure of the different types of vegetation has been analyzed. 176 plant species belonged to genera 143 kinds and 49 families were indentified. The most important families are the Leguminosae (14.77 %), Rubiaceae (13.63 %) and Apocynaceae (10.79 %). About 15.37 % (27 species) of this flora represents the particular statute species. Among the inventoried species, 11 are exploitable species or exploited as timber of which ten are forest species. Due to richnes of its flore and flora dynamic, the Unburned Savannah must be protected. Based on an ascending hierarchical classification performed by using 11 linear surveys, this study has demonstrated the existence of a floristic variability to three groups.
The Dahliafleur Partial Nature Reserve, located in the town of Bingerville, is part of the great Ivorian protected area network. Unfortunately, very little is known about its floristic diversity, and even less about the structure of its vegetation. This work intends to characterize its floristic and structural aspects, through 13 surface surveys and an itinerant survey carried out in the northern, central, and southern zones of this area. The data analysis revealed that the Dahliafleur Partial Nature Reserve includes 135 species. These species are divided into 110 genera and 53 families. It has 26 special-status species and the highest diversity index of any urban forest. The diametric structure shows histograms in the shape of an "inverted J" for each of the areas. This pattern is typical of a forest in a good state of conservation and with good regeneration capacity. This result shows the importance of this reserve for the conservation of floristic biodiversity.
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.
