Abstract

Analysis of the invasive aquatic flora in the water bodies of the city of Daloa (Central West of Côte d'Ivoire).

Abstract

Objective: The main objective of this study, carried out in the water bodies of the city of Daloa (West Central Côte d'Ivoire), was to gain a better knowledge of the invasive aquatic flora with a view to its efficient management. Methodology and Results: The data collection combined the surface and itinerant survey methods. After the inventory, the actual identification of the harvested species was done from the global database of invasive species (www.issg.org/database/welcome/), documentation on Ivorian flora and with the support of a systematist from the National Center for Floristics of the Félix Houphouët Boigny University. The inventory was carried out at four sites using direct sampling. The flora of the identified EAVs consists of ten species, divided into ten families, ten genera and two branches. It appears that Nymphaea lotus, Cyperus articulatus, Typha domingensis and Eicchornia crassipes are the most dominant. Among all these species, those belonging to the Angiosperms branch are the most represented. Conclusion and application of results: Nymphaea lotus, Cyperus articulatus, Typha domingensis and Eicchornia crassipes are the most dominant species in the water bodies of the city of Daloa. The proliferation of these species is favored by pollution of agricultural and household types that are practiced around water bodies. This induces the regression of the surface of water bodies, the reduction of fishing activities and the proliferation of mosquitoes responsible for malaria.
