Internal tidal polders and backward relocation of dykes
Along with the tidal polders in Coldemüntje and near Stapelmoor, the Master Plan Ems 2050 also foresees about 450 to 500 hectares of land for additional polders, which shall be installed behind the main dyke or formed through backward relocation of dykes. Their location depends on the availability of land and the results of the feasibility study on the tidal reservoirs, as well as their effectiveness with regard to improving water quality. A tidal polder on the Leda is also included in the measures. No land has yet been acquired for the establishment of such typical estuary habitats, as these measures largely depend on the results of further planning and feasibility studies. Furthermore, Article 13 (2) of the Master Plan Ems 2050 states that the development of tidal riparian forest, reeds, and marshland is the priority, followed by the formation of estuary habitats after considerable reduction of silt in the Ems.
