Characterization of the Ichthyological Population of Hydrosystèmes in the Lagoon Area of the Azagny National Park (Ivory Coast)

The conservation of protected areas is nowadays one of the concerns of international and national institutions. This study aims to contribute to better conservation of the ichthyological fauna of the lagoon area of the Azagny National Park (PNA). This national park has been dealing with the harmful effects of human activities for years. Thus, from March 2019 to February 2020, sampling campaigns were carried out to characterize this space, for better conservation. The results obtained are based on the analysis of abiotic and biotic (fish) data collected at 6 stations. The physicochemical parameters were measured using a multiparameter and the fish population collected using 10 gillnet batteries of 10, 25, 30, 35, 40 and 50 mm mesh void. The analysis of the ichthyological population of the lagoon area reveals a diversity of 53 species belonging to 30 families and 12 orders. 11 species were newly collected while 31 species previously recorded in these hydrosystems were not captured in the present study. The Shannon (H’> 2) and Equitability (E> 0.5) indices calculated reflect a good organization and stability of the ichthyological population of the hydrosystems of the PNA lagoon zone. The Monte-Carlo test indicates that the variables rate of nitrate, width, rate of dissolved oxygen, water temperature, alkalinity, salinity, rate of dissolved solid and phosphorus are those which discriminate specific richness, abundance and the distribution of the stand.

The Impact

The present study concerns the diversity of the woody tree flora of Mont Sangbé National Park (West of Côte d'Ivoire). The main objective was to analyze the diversity of the woody tree flora of this park impacted by human activities. Specifically, it involved (1) identifying the anthropogenic factors of the PNMS, sources of impact (2) assessing the impact of these activities on the diversity of the woody tree flora of the PNMS and (3) propose measures to mitigate biodiversity losses. To carry out the study, a device of 14 square blocks of 1 ha each was used on the impacted sites and the control sites in the different biotopes of the park. Each block was subdivided into 100 square plots of 100m² each. The results show that anthropogenic activities have reduced the flora richness of the park, modified its floristic composition and caused the disappearance of some status species. It was proposed as a measure to step up surveillance of the park.

Material Evidence

Cultural resources are commonly defined as resources that provide material evidence of past human activities. These resources are unique, as they are both finite and non-renewable. This provides a challenge for traditional visitor use management since these resources have no limits of acceptable change. However, with nearly every national park in the US containing cultural resources, coupled with ever-growing visitation, it is essential that managers of parks and protected areas have the ability to make science-informed decisions about cultural resources in the context of visitor use management. We propose a framework that can help provide context and exploration for these challenges. Drawing on previous literature, this framework includes risk-based approaches to decision making about visitor use; visitor cognitions related to cultural resources; emotions, mood, and affect related to cultural resource experiences; creating and evaluating interpretive programs; deviant visitor behaviors related to cultural resources; and co-management.
