The Kilum-Ijim Forest is an area of mountain rainforest in Cameroon's North-West Region.
It is the largest area of Afromontane forest left in West Africa.
The area is an important one for biodiversity, including the endemic Bannerman's turaco and banded wattle-eye.
The programme works so well that the boundaries of the forest, as mapped by satellite imagery, are expanding, and the success of the idea has led to another sister project in Cameroon, the Bamenda Highlands Forest Project.
The Kilum-Ijim Forest is an area of massive land which has extreme biodiversity, ranging from tropical rainforest to lake Biomes.
