The Neuendorfer Wiek and Beuchel Island Nature Reserve (German: Naturschutzgebiet Neuendorfer Wiek mit Insel Beuchel) is a nature reserve on the German Baltic Sea island of Rügen in the state of Mecklenburg-Vorpommern.
Its conservation aim is the preservation of a characteristic and representative section of the North Rügen Bodden Chain, which contains rare and threatened biotope types as well as habitats for a rich variety of fish and diverse breeding and roosting birds.
The southern part of the Neuendorfer Wiek was dyked in the late 19th century and drained by two wind pumps (Schöpfwerke).
Wash margins, brackish water reed beds, salt marshes[4] and steep coasts[5] are typical of the nature reserve.
The island of Beuchel is an important breeding ground for many bird species, such as ducks, geese, swans, mergansers, waders, gulls and common and Sandwich terns.
