Site characteristics

Located in southwestern Nigeria, the site was upgraded from wildlife sanctuary to national park in 1999 (Nwankwo & Halilu 2020).

Threats

Large-scale illegal logging (which has been going on since the 1950s) and the expansion of large rubber and oil-palm plantations nearby are the biggest threats to the park. About 50,000 people in 45 villages live in and around the park, and the population is increasing. Many are recent immigrants attracted by possibilities of employment in the timber and plantation industries, or by farming and hunting opportunities (BirdLife International 2020).
