Eriskircher Ried, Nature reserve next to Lake Constance, Germany.

Eriskircher Ried is a nature reserve along the Lake Constance shore between Friedrichshafen and Langenargen. It comprises meadows, wetlands, and alluvial forests that line the lakeshore.

The Würm glaciation, around 20,000 years ago, saw the Rhine foreland glacier shape the basin that became Lake Constance. Since the last ice age, sediments from the lake and from the Schussen and Rotach rivers have built the subsoil of the Ried, with moraine material exposed in places. The reserve was designated by decree on 8 July 1939 and re-established with an extension on 10 October 1983.

The name Streuwiese comes from the winter-cut hay, which was used as bedding in stables because the lakeside meadows were flooded for weeks each year and could not serve as fodder. Schussen and Rotach once meandered in loops; they were straightened at the start of the 20th century, and the Schussen was cut off from its loops, leaving the Stillwasser and Altwasser behind.

The reserve lies between the mouths of the Rotach and the Schussen, west and south of Eriskirch and east of Friedrichshafen. The lakeshore zone is flooded for weeks almost every year, and the reeds extend up to a kilometre out into the lake; at low water, mudflats appear. Parts of the area are also protected as FFH and bird-sanctuary zones, so visitors should stay on the paths.

Water levels naturally fluctuate throughout the year, forcing plants and animals to adapt to these changes. Regular mowing of the meadows is also crucial for maintaining the diverse plant and animal life in this place.
