Abstract

Phytogeographic theories complement classic biodiversity data with spatial information and constitute a potential tool for conservation biology. The studies presented in this paper analyse diversity patterns of Lycophytes and Ferns in the mountains of Kahuzi-Biega National Park (KBNP) which is located in other regional endemic centers of the DRC according to White (as stated in his book the vegetation of Africa). We conducted a phytogeographical analysis of this massif from the mountain areas of Kahuzi-Biega and evaluated its floristic, the Lycophytes and Ferns affinities with other regional endemic centers of DRC. The analysis is based the specimens and a detailed consultation of the bibliography on Phytogeographical of Lycophytes and Ferns in the DRC.  The Data projection in different regional centers of endemism along the lines of White shows that the majority of species are liaison species between regional centers and endemism areas of the DRC. The sub-montana zone of the KBPN is considered to be a transitional area between the Kahuzi mountain range and other regional centers of endemism. In its part of conservation, I show how these species are threatened by human activities exercised in this Park. These characteristic species of mountains should be retained in order to better use as indicator species of mountains forest degradation.  Hence, some strategies of conservation are proposed.
