The nature park is divided into 3 zones:
Theareaof the ponds. (The largest areas made of reeds, bulrushes and wetlands).
The zone of dunes. (The zone consists of lagoons and brackish marshes and dunes).
The area of the island “Caramany”. (The island is located in the center of Fluvià, this island is preferred by many birds as a nesting site).
Most of the flora of this park is located in the zone of the half-flooded or are completely flooded wetlands so-called.
There are plants typical of this area such as the Salicornas (Athrocnemum), the beach grass (Ammophila arenaria), which you will find on the dunes next to the beach and the yellow lily (Iris pseudacorus).
At last we must not forget the numerous fauna that has setteld in the nature park. Such as the otter (Lutra lutra) and the stork (Ciconia ciconia). Furthermore, there are types that have been successfully introduced some years ago, such as the fish Espinoso (Gasterosters aculeatus) and the fish Afanio (Aphanius iberus). These two fish are very characteristic of these waters and the area.
