The NDP must indicate where in or along the Scheldt estuary measures must be taken on the medium long term (i.e. up till 2010), so that the objective of 2030, as set in the long term vision of the Scheldt estuary, can be reached. The NDP must indicate what is important for the natural functioning of the estuary, which improvements can be made, where measures can be complementary in the field, and which criteria are to be used as a reference. Also the Habitat Directive and the Bird Directive should be incorporated in the NDP.
