<!-- 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 Oni Forest Reserve
* Chimpanzees have gone extinct at Oni Forest Reserve in the 90s.
* The site has a total size of 56 km².
* Key threats to chimpanzees are habitat destruction due to extensive farming.
* Conservation activities are not documented.
= Site characteristics = <!-- A paragraph summary of physical and geographic aspects of the site, and a table of key information -->
The site is located in the Ekiti state in Nigeria. Chimpanzees have not been observed in the reserve since 1993, and in its current condition it holds little value in terms of its natural biodiversity. Due to extensive farming, the site has in effect become unofficially de-gazetted (Greengrass 2006).

= Threats = <!-- a text overview of threats, followed by a table of key threats -->
The main threats to chimpanzees and wildlife at the reserve include illegal and widespread farming in the 1990s and timber extraction that began in 1987 (Greengrass 2006).

= Challenges = <!-- Overview of challenges in ape conservation -->
Illegal clearing and farming occurred with the assistance of a corrupt police administrator who prevented the forestry department from acting against it. Violent attacks on forestry staff have also occurred on several occasions (Greengrass 2006).
