In order to have the Kahuzi-Biega National Park considered a World Heritage Site, it is essential to have the indigenous population (the pygmies) to be evicted. They were not happy with the way they were kept out of their natural environment, because they live from hunting and gathering that can only be done in the forest, unfortunately for them being a reserve.
Indeed, the pygmies found themselves outside the park but they still have the courage to allow the Congolese Institute of Nature Conservation (ICCN) to protect the ecosystem in Kahuzi-Biega Park. They are also major guides and collaborators for scientific research. They contribute very significantly to the work by providing accurate information on the species of the park: identification, distribution, eco-ethology, use of the environment, traditional use of species by pygmy communities. It is often that they deserve to be co-authors of the scientific work on the Kahuzi Biega National Park (PNKB).
In the fight against poaching, pygmies are essential by the watching they provide and the information they provide about the movements of poachers.
