Located along the Niger River, this park touches the prefectures of Faranah, Dabola, Kouroussa, Kankan and Kissidougou. It contains many animal and plant species, according to Captain Abdoulaye Kouyaté, Chief Conservator. On the Faranah side, the park is about 70 km north-east of the capital and is linked by a rural track to Sidakoro, in the rural commune of Bendou.

It covers an area of one million 200 000 hectares and contains two nuclei: Mafou with 55 000 hectares and Kouya with 65 000 hectares. All the animal species of the savannah live in these two cores. Surveys in the park conducted during 1996–97 revealed a diverse mammalian fauna of 94 species including:
  • 24 rodents,
  • 18 bats which of the Franquet's epauletted fruit bat and the horseshoe bat,
  • 17 carnivores which of the Caracal, the Egyptian and Gambian mongooses and the spot-necked otter,
  • 14 ungulates which of the giant forest hog, the kob and the waterbuck,
  • 9 insectivores which of the four-toed hedgehog and the climbing shrew,
  • seven primates which of the chimpanzee and the Senegal galago,
  • giant and tree pangolins and the African savanna hare.
  • The African elephant) once occurred in the park but is now extinct.

However, according to the conservators who watch over this unknown treasure, several species are in danger of extinction. These include panthers, chimpanzees (currently protected by a French NGO on the site), pangolins, hippos, buffaloes, aardvarks... In 1997, lion returned to the protected area, probably migrating from the Tinkisso River region.

At the entrance to the park, a beautiful city of nature conservationists has been built. Half a dozen agents, led by Captain Abdoulaye Kouyaté, surround the entrances, preventing poachers and nature abusers from infiltrating the park.

Situated in the Niger basin, UNESCO reminds it is part of the sudano-guanese vegetation zone. The biosphere reserve plays an important role in protecting the primary open dryforests which are believed to represent the last relicts in Guinea and probably in all western Africa.
Fig. 7 - S2 (09.03.2022) - Burnt areas and fire fronts are visible in March.
It covers open dry forests, gallery forests along the Niger River and its tributaries, woodland and herbaceous savanna, ponds as well as agroforestry ecosystems. Among scientific projects undertaken in the biosphere reserve are species inventories, a rehabilitation project for chimpanzees and the monitoring of the West African Manatee and the endangered endemic catfish Arius gigas.

More than 4000 people live in the biosphere reserve who mostly depend on agriculture, stock raising, hunting, gathering and fishing.

The area has a high potential for eco-tourism development. A development plan (1999-2003) has been established in order to improve the community participation in the management of the biosphere reserve.

Social, tourist and forestry development projects will be carried out in close cooperation with the local communities.
