Diversité botanique dans le sud du parc national de Taï, Côte d’Ivoirean

Abstract

Botanical diversity of the South of Taï National Park, Côte d’Ivoire

The Tai National Park (TNP) is one of the last vestiges of ≪ primary ≫ forest remained in West Africa. The northern part is almost well known but the southern one is not. To mitigate this lack, we conducted a study in the South of the TNP. To achieve the inventory, two methods were used: “walk set up” and the “plot set up”. Nine hundred height plants species were recorded. They belonged to 550 genera and 116 families. The richest families were Rubiaceae, Euphorbiaceae and Caesalpiniaceae. Among all the species, 175 were endemic of West African forests, 11 endemic to Ivorian forests and 61 “sassandrian”. The study showed that for tree species with dbh ≥10 cm

Hymenostegia afzelii, Strombosia pustulata,  Diospyros sanza-minika, Funtumia africana, Calpocalyx brevibracteatus and representatives of Caesalpiniaceae, Euphorbiaceae and Ebenaceae families were the richest and had the highest values of IVI and FIV. Endemic, “sassandrian”, rare and threatened species constitute the major characteristic of the TNP and confirm that it includes in the Guinean Forests of West Africa Hotspot.
