Site characteristics[edit]

The reserve is located in the state of Ondo, Nigeria.

Area 242 km²
Coordinates 6.96879,5.5626
Designation Forest Reserve
Habitat types Plantations, subtropical/tropical heavily degraded forest

IUCN habitat categories Site designations

Ape status[edit]

The site was superficially surveyed in 2006. Two nests were observed in Owo Forest Reserve in 1997, but it remains unconfirmed whether or not chimpanzees still survive here- a more extensive survey is needed to confirm chimpanzee occurrence (Greengrass 2006).
