Impacts of the anthropic activities of the decade of politic and army crisis on the diversity of the woody forest plants in the south of the Sangbé Mount national park, Côte d'Ivoire

This study relates to the impact of the anthropic activities of the decade of Politic and army crisis of Côte d'Ivoire, on the dynamics of the woody plants family of the Southern part of the National park of the Sangbé Mount. The main aim was to characterize the impact of these activities on the dynamics of the arborescent ligneous family of the Park. In a specific way, it was: (1) to identify the sources activities of impact; (2) to analyze and evaluate the impacts of these activities on the dynamics of the ligneous family and (3) to put forward measures of attenuation or corrective to compensate for the losses in biodiversity. With this intention, floristic inventories were carried out according to the method of the of surface in a device made up of 20 small squares of 2000 m ² (50mx 40m) each one gathered in five blocks directed according to the cardinal points. Got results shows that the anthropic activities caused a strong reduction of the density, diameter, size and a reduction of the diversity of the woody plants family particularly that of the woody species with particular status. The compensation of these losses can result from the fight against the aggressions of the park by the sensitizing of the bordering populations and the biological control of Chromolaena odorata.
