Dollart
The Dollart (German name, ) or Dollard (Dutch name, ) is a bay in the south‑eastern Wadden Sea at the Germany–Netherlands border, west of the Ems estuary. It forms the innermost part of the Ems–Dollart estuarine system and is characterised by extensive intertidal flats, salt marshes and shallow channels. A large proportion of the surface falls dry at low tide, creating internationally important feeding grounds for migratory shorebirds and waterfowl. The remaining unembanked forelands belong to the transnational Wadden Sea World Heritage Site.
