The 12 hectares of the area consist of four former fish ponds in the Molenbeek valley. The ponds have been managed in a nature-friendly way for ten years. They are a good place to make the first spring observations of Reed Warbler, Marsh Warbler, Blackcap and Garden Warbler. During the winter half-year, in addition to modest numbers of Tufted Duck, Common Pochard, Common Teal are present. Other duck species are seen to a lesser extent Gadwall, Northern Shoveler.
In recent years many rareties were seen during migration, like Black-necked Grebe, Red-necked Grebe, Purple Heron, Great Bittern, Long-tailed Duck, Penduline Tit, Common Scoter and Squacco Heron.
