River Gambia National Park, National park on the Baboon Islands in Central River Division, The Gambia

River Gambia National Park lies on the left bank of the Gambia River in Niamina East district, Central River Division, and includes the 585 ha Baboon Islands archipelago: one large island and four small ones. The flat islands carry riparian forest, a form of tropical rainforest. The park is not open to the public, and the islands may not be entered.

The protected area was established in 1978 to safeguard the river and its islands from overuse. A year later, a program began to bring back chimpanzees that had disappeared from the region roughly a century before.

The park's name comes from the Gambia River, which forms its northern boundary; the Baboon Islands are named after the Guinea baboons that share the reserve with the chimpanzees. Stella Marsden, daughter of Abuko Nature Reserve founder Eddie Brewer, has directed the Chimpanzee Rehabilitation Project since 1979 and was appointed OBE for it.

The park is not open to the public, and landing on the Baboon Islands is forbidden because chimpanzees can be aggressive to humans; exceptions need government approval. Even boat trips around the islands were sharply restricted in 1998. The park lies on the left bank of the Gambia River in Niamina East district, next to Nyassang Forest Park.

Chimpanzees had become extinct in the Gambia in the wild by the early 20th century. Since 1979 the Chimpanzee Rehabilitation Project, led by Stella Marsden, has released confiscated animals onto the three largest islands, where by July 2006 there were 77 individuals in the third generation. Marsden was appointed OBE for this work.
