<!-- 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.

Officially known as the Ejagham Council Forest Reserve, the site is contiguous with the northern boundary of [[Korup National Park]] and also shares a border with the Oban division of the [[Cross River National Park]] in Nigeria. The reserve is part of the proposed CRIKOT World Heritage Site, which encompasses protected areas in Nigeria and Cameroon, including Korup National Park, Cross River National Park, [[Takamanda National Park]], [[Mbe Mountains]] and [[Mone River Forest Reserve]]. The region holds the richest butterfly diversity in Africa with over 1,000 lowland forest species. The area is also a stronghold for regionally endemic primates and contains an extremely high diversity of plants, reptiles, and amphibians ([https://whc.unesco.org/en/tentativelists/6204/ UNESCO]).

Site characteristics

Officially known as the Ejagham Council Forest Reserve, the site is contiguous with the northern boundary of Korup National Park and also shares a border with the Oban division of the Cross River National Park in Nigeria. The reserve is part of the proposed CRIKOT World Heritage Site, which encompasses protected areas in Nigeria and Cameroon, including Korup National Park, Cross River National Park, Takamanda National Park, Mbe Mountains and Mone River Forest Reserve. The region holds the richest butterfly diversity in Africa with over 1,000 lowland forest species. The area is also a stronghold for regionally endemic primates and contains an extremely high diversity of plants, reptiles, and amphibians (UNESCO).
