<!-- INSTRUCTIONS FOR UPLOADING SITE INFORMATION
- Wiki pages contain information in paragraphs, tables, lists, and images.
- Please consider whether any information you would like to add is sensitive and could be misused to harm apes. Please do not add such information. If unsure, you can contact the Wiki manager (contact details on start page) for clarification.
- 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.
- Text paragraphs and images are not restricted, so text format and images can be chosen as desired.
2) List format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
- Tables and keyword lists are extracted as data, and so have the following restrictions:
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.
1) Table structure cannot be changed
2) Keyword format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
3) Keywords must be taken from the list of permitted words, or added to the list of permitted keywords. A link to the keyword list page is found adjacent

Situated in southeast Nigeria, Cross River National Park (CRNP) was established in 1991 and is divided into two sections: the smaller Okwangwo Division (1,000 sq. km), and the larger Oban Division(3,000 sq. km). The sections are separated by about 50 km of disturbed forest (BirdLife International 2020). Over 350 species have been observed in the park, which is one of the most ornithologically diverse sites in Nigeria and is designated as an Important Bird Area (BirdLife International 2020). The Okwanwgo section is adjacent to Takamanda National Park in Cameroon; together they represent the most important area for the critically endangered Cross River Gorilla ([https://nigeria.wcs.org/wild-places/cross-river-np-okwangwo.aspx WCS]). Oban is contiguous with Korup National Park in Cameroon, and it is an important watershed, draining into the Cross river in the northern part, and Calabar, Kwa, and Korup rivers in the south (BirdLife International 2020). A total of 1,303 flowering plants, 141 lichens, and 56 moss species have so far been documented in Oban, making it remarkably rich in floral diversity. Both sections of CRNP are home to several mammal species, including forest elephants (''Loxodonta africana cyclotis''), Preuss's red colobus (''Procolobus preussi''), mandrills (''Mandrillus leucophaeus''), leopards (''Panthera pardus''), and Sclater's guenon (''Cercopithecus sclateri''), a Nigerian endemic (BirdLife International 2020). The contiguous Oban-Korup forest is famous for its rich butterfly diversity ([https://nigeria.wcs.org/wild-places/cross-river-np-oban.aspx WCS]).

Illegal logging is the most important threat to the park and has worsened since the withdrawal of funding by the European Union. CRNP is important for the protection of the catchment of the Cross river. As the human population grows, the demand for farmland is leading to encroachment in areas of the park previously considered inaccessible. Traditional exploitation of natural resources such as hunting, fishing and shifting cultivation, adversely impact the park (BirdLife International 2020).
