Nigeria's forest reserves protect critical ecosystems across diverse climatic zones. Here are five notable reserves safeguarding the nation's natural heritage:
Established in 1911, this 1,192-hectare reserve harbors endangered species including chimpanzees and the white-throated guenon, alongside diverse flora.
Dating to 1912, Osse's 1,720 hectares shelter rare and endemic species. Its trails attract birdwatchers and nature enthusiasts.
Founded in 1916, this 3,010-hectare tropical forest boasts exceptional biodiversity. Note: Mount Cameroon (4,070 m), mentioned in some sources, actually lies across the border in Cameroon—Oban Hills' highest peaks are lower but equally ecologically vital.
Nigeria's largest national park (6,402 km², established 1991) protects mountain gorillas, Nigerian dwarf crocodiles, and vast savanna-woodland mosaics.
Spanning 4,000 km² of rainforest (est. 1991), this park shelters drill monkeys, forest elephants, and countless endemic species—part of a proposed transboundary protected area with Cameroon.
These reserves face pressures from logging, agriculture, and poaching, but remain essential for Nigeria's ecological resilience and global biodiversity commitments.
