The lands forming the Nature Reserve are mainly cultivated with corn, rice, and poplars. In the heart of the Nature Reserve there is a monospecific forest now made up of a locust tree coppice woodland, while until 1976 it consisted of large oaks housing about 1,500 couples of herons. Since the establishment of the Nature Reserve, the number of couples nesting in the area has been increasing: among them, night herons, the little egrets, and gray herons. (No admittance in the area, except for research reasons).
