In 2006, chimpanzees and signs of chimpanzees (nests and vocalizations) were observed by the Owena river in the core area of the reserve (Greengrass 2006). Similarly, in 2012 the distribution of chimpanzees was confined to the core area of the reserve (segment OA2), encompassing approximately 39.22 km², or 5.78% of the total forest reserve (Ogunjemite & Olaniyi 2012).

West Africa > Nigeria > Oluwa Forest Reserve

Summary[edit]

  • Nigeria-Cameroon chimpanzees (Pan troglodytes ellioti) are present in Oluwa Forest Reserve.
  • The population size is unknown.
  • The chimpanzee population trend is unknown.
  • The site has a total size of 678 km².
  • Key threats to chimpanzees are hunting, logging, and expansion of land for agriculture.
  • The site is part of the Omo-Shasha-Oluwa project, implemented by the Nigerian Conservation Foundation, which aims to connect three forest reserves and manage them as a wildlife sanctuary.

Site characteristics[edit]

Designation Forest Reserve
Habitat types Subtropical/tropical low moist forest, plantations

Ape status[edit]

In 2006, chimpanzees and signs of chimpanzees (nests and vocalizations) were observed by the Owena river in the core area of the reserve (Greengrass 2006). Similarly, in 2012 the distribution of chimpanzees was confined to the core area of the reserve (segment OA2), encompassing approximately 39.22 km², or 5.78% of the total forest reserve (Ogunjemite & Olaniyi 2012).

Together with Omo and Shasha forest reserves, Oluwa is part of the Omo-Shasha-Oluwa project, implemented by the Nigerian Conservation Foundation, which aims to connect the three areas (PNI 2011). Although Omo and Shasha reserves are connected, Oluwa forest is isolated. The plan is to manage the Omo-Shasha-Oluwa areas as a wildlife sanctuary and permit human use where it is compatible with forest conservation. Other conservation activities included in the plan are the re-gazettement of forest reserve areas, community development, environmental education, research, eco-tourism, and long-term financing through REDD carbon credits (PNI 2011). Further information on the advancement of these activities has not been reported.

Research activities[edit]

A new nesting behavior was observed in the Oluwa Forest Reserve chimpanzee population during a survey in 2011-2012 (Ogunjemite & Olaniyi 2012). The majority of nests were built on rock platforms, perhaps due to the absence of tree species that are usually used for nesting (Ogunjemite & Olaniyi 2012).
