The major part of this nature reserve, measuring 44 hectares, is situated on the old ramparts of Damme. The canals of this system for the town's defence have developed into reedland, boggy wood and meadow land. Their botanical value is unique with species such as the buckler fern and the gray-crested shield fern. In the pond behind the Schellemolen little grebes and coots brood. The adjacent vast pastures are an important stop for the migrant geese during the winter half-year. In spring the black-tailed godwit and the lapwing search for a brooding place.
