During the decade of political and military crises of the 2000s in Ivory Coast, the classified forest of Haut-Sassandra (CFHS) located in the Central West has undergone many changes in its vegetation cover resulting in a significant change in its floristic composition and structure. The objective of this study is to determine after conflicts, the causative agents of these changes. To achieve this, a systematic sampling of damage types was done within the CFHS following 18 transects of 500 m each one. The agents responsible of these degradations were also identified. A total of 12 types of degradation have been identified of which four are most representative specifically slash and burn of stem base, association of food crops, falling trees and cocoa farms. The classification of geographic locations in decreasing degradation order revealed that the North and the East are the most altered by Human activities. With over 81.96% of presence on transects, cocoa farming is the main activity which causes the degradation of CFHS. With a percentage of 95%, Human is the mainly responsible of degradation observed in the CFHS. The crises arising conflicts have therefore promoted a significant human impact of CFHS. The lack of environmental monitoring during this period is one of the factors behind this strong anthropisation of CFHS.
