The IBA includes a large shallow bay with a natural shoreline, including mudbanks, reedbeds and marshy areas. It also covers part of the river Rhine between Lake Constance and Untersee. The Swiss part of a transboundary IBA together with the German IBA «Untersee of Lake Constance» (site DE231). The site holds 20’000 or more waterbirds in winter, on a regular basis. Waterbird numbers are given for the whole bay of Ermatingen including both the Swiss and German IBAs. One of the main threats is disturbance from recreational activities, particularly boating and walking. Hunting is allowed in some places.
