<!-- INSTRUCTIONS FOR UPLOADING SITE INFORMATION
 +
- Wiki pages contain information in paragraphs, tables, lists, and images.
 +
- Text and images are not restricted, and their formats can be chosen as desired.
 +
- Tables and lists are extracted as data, so the following restrictions apply to them:
 +
  1) Table structure cannot be changed.
 +
  2) List format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
 +
  3) To make information comparable across wiki pages, keywords must be taken from the list of permitted words, or added to the list of permitted keywords. This is why we use official lists, e.g., IUCN classification lists, in our tables.

* Nigeria-Cameroon chimpanzees (''Pan troglodytes ellioti'') are absent in Ogbesse Forest Reserve.
 +
* Chimpanzees have not been seen in the reserve since 1996.
 +
* The site has a total size of 73 km².
 +
* Key threats to chimpanzees are logging, hunting, and clearing forest for agriculture and hardwood plantations.
 +
* Conservation activities are not documented.

 +
 +
The Ogbesse Forest Reserve is located close to the Ekiti state capital of Ado-Ekiti, Nigeria. The reserve has been completely logged and cleared for farms and teak and gmelina plantations (Greengrass 2006).

Chimpanzees have not been sighted in the reserve since 1996; it is certain from the unsuitable  habitat that they are extinct now. The reserve is small in size, its location close to the state capital and a road runs through it to Ise Town; these are probably all factors that have contributed to the quick over-exploitation of its natural resources (Greengrass 2006).
