Characteristics of the woody stands of the route of the great green wall of the provinces of Wadi-Fira East and Ennedi East of Tchad

Abstract

To make proposals for sustainable management strategies for the Great Green Wall, knowledge of the characteristics of the woody population along the Chad route is essential. The purpose of the study is to characterize the flora and woody vegetation along the route of the GGW of Chad, specifically in Wadi Fira East and Ennedi East. The methodology used consisted in determining the floristic composition and the structure of the woody stand in the two sites. Floristic inventories made it possible to identify 8 species divided into 7 genera and 4 families in the Wadi Fira East site while in the Ennedi East site we have identified 7 species divided into 6 genera and 4 families. The woody flora is dominated by Mimosaceae. The density of woody plants (39.43 ind.ha-1) is higher in Ennedi East than in Wadi Fira East (36.62 ind.ha-1); However, the overlap at Wafi Fira East (559.428 m².ha-1) is greater than that at Ennedi East (499.844 m².ha-1). The results obtained show that the species most suited to ecological conditions for the success of GMV are Acacia raddiana and Balanites aegyptiaca which are suitable for the restoration of these ecosystems.
