The karstic relief of the Mostalla, Segària and Migdia sierras feed these broad marshlands which were once separated from the sea by a strip of sand dunes. Today there are still pools of clean water, which are practically always flooded, and an extensive area of canes providing nesting sites for a variety of birds, including the marsh harrier and the ferruginous duck. A number of man-made canals criss-cross the area, and in these waterways live the regional samaruc (Valencia hispanica) and the loach. The Pego-Oliva Marshlands Nature Park Information Centre is located in the town of Pego (tel. 96 640 0251).
