Kahuzi-Biega National Park is divided into two zones connected by a narrow corridor: rain forest mountain (or Afro-montane forest) on one hand, and the lowland rainforest (Guinea-Congo, relatively wet) on the other hand. It is a rare African regions where the transition between these two types of rain forests remained largely intact.
So far, over 1178 plant species have been recorded at high altitude, making it the third Albertine Rift website in terms of species richness after the Virunga National Park in DRC and the Bwindi Impenetrable Forest in Uganda . For cons, the lowland flora is still little known.
The inventory of species endemic to the Kahuzi-Biega National Park is far from complete, and we even discovered many new species belonging mainly to the families of Balsam Orchidaceae & Violet, Spurge, Araliaceae, Anacardiaceae, and many others families with one particular species (Fischer, 1995).
The mountainous part of the park is covered with mostly forest vegetation, in which there are other training related to specific soil conditions: waterlogged soils, wetlands, flooded, or breastplates laterite.
According to their appearance and their flora composition, depending on the altitude, forests KBNP differentiate into floors lowland (678- 1250 m), sub-mountaineers (1250-1700 m), mountaineers (1700-2600 m) and Afro -subalpins (2600-3308 m) (Mangambu and al.2013).
The protected canopy Park has a regulatory effect on the hydrology of the region. Is notably watershed protection. Furthermore, the exceptional forest cover KBNP an important carbon sink contributing to the fight against climate change globally
