WIWO-reports published

Since 1991 several ornithological surveys and studies have been carried out in the Waza-Logone gloodplain. A total of 346 bird species has been recorded since 1991. The most numerous waterbird species are White Pelican, Squacco Heron, Little Egret, Cattle Egret, Glossy Ibis, White-faced Whistling Duck, Collared Pratincole, Ruff and Black-tailed Godwit. For the resident species Black-crowned Crane the Logone gloodplain is one of the last strongholds. For Collared Pratincole the area is one of the major wintering areas in Africa. Sedge Warbler and Reed Warbler are vvery abundant as well as Barn Swallow.

Annual counts of wintering waterbirds in the Lake Chad Basin Area in Cameroon (The Logone river and its floodplain) started in 1993 ans showed the importance of the Logone floodplain for wintering waterbird species.

The February 2000 census presented in this report counted nearly 230,000 waterbirds and waders in the floodplains on both sided of the Logone river in Cameroon and chad. Waterbird numbers in the Lake Chad Basin Area have been increasing since 1995, indicating that the floodplain restoration of the Waza-Logone Project has a positive effect on waterbird habitat quatlity.
