The British Trust for Ornithology have also been monitoring wader birds using the Bay and adjacent foreshore since 1989. They have produced a report for each winter period since commencement. The monitoring is due to be completed during the winter period of 2002/03. An interpretive report on the impact of the impoundment upon wader birds that formerly used the bay will be prepared.

The area covered by this list consists of the entire area enclosed within the barrage wall, and a small distance up both of the contributing rivers, the Ely, and the Taff. This  list is an attempt to outline many of the major species of bird identified in the area since barrage closure.

In compensation for the loss of the Cardiff Bay habitat, a 1000 acre wetland reserve was constructed on the Gwent Levels.  The idea of the scheme , which was completed in 1999, is to provide habitats for nationally rare species of birds.  Further information can be obtained from the Countryside Council for Wales who now operate and manage the reserve.
