Abstract
This study contributes to the knowledge of the diversity of flora and the updating of plant data from thermal water sites in eight sites (Burhinzi, Luhwindja, Kankulé, Kakonde, Cimenki, Cizirhi, Buhandahanda, Nyangezi) located in the vicinity of Bukavu city. The phytosociological method was used in a 10 m sampling area on either side of the site, in which two 4 m2 surveys were conducted. The sampling method consisted of a quantitative inventory to identify the various specific abundances. The results show an inventory of the plant species present in the thermal sites grouped into 33 families of 83 genres and 101 species of which the families of Asteraceae, Poaceaeand Fabaceae are the most abundant. Herbs dominate trees and most of the flora studied is found in therophytes. Comparison of the specific richness between the different sites based on the ANOVA test shows that there is no significant difference between the sites (P > 0, 001; F=1,881).
Keywords: Thermal waters, quantitative inventory, floral diversity, specific abundance, Bukavu, South Kivu
