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).
