Cross-Niger transition forests : ウィキペディア英語版 | Cross-Niger transition forests The Cross-Niger transition forests are a tropical moist broadleaf forest ecoregion of southeastern Nigeria, located between the Niger River on the west and the Cross River on the east. Once a rich mixture of tropical forest and savanna woodland covered these low, rolling hills but today this is one of the most densely populated areas of Africa and today most of the forest has been removed and the area is now grassland. ==Location and description== The ecoregion extends across the Nigerian states of Abia, Akwa Ibom, Anambra, Ebonyi, and Imo, covering an area of . The Niger River separates the Cross-Niger transition forests from the Nigerian lowland forests to the west, which probably resembles most closely the original environment of the Cross-Niger ecoregion. To the south and south-west lies the Niger Delta swamp forests. To the north, the Cross-Niger transition forests yield to the Guinean forest-savanna mosaic of the drier interior. The climate is wet, becoming drier further inland, with a dry season from December to February.
