 This natural habitat is a reminiscence of the old swamps that covered these lands until the 8th century.The lush vegetation represents a very good camouflage during the nesting season, and the reservation is home to large numbers of protected birds including the pied avocet ("Recurvirostra avosetta"), the little egret ("Egretta garzetta"), the great egret ("Egretta alba"), the black-winged stilt ("Himantopus himantopus"), the grey heron ("Ardea cinerea"), the squacco heron ("Ardeola ralloides"), the little bittern ("Ixobrychus minutus"), the purple heron ("Ardea purpurea") and the black-crowned night heron ("Nycticorax nycticorax").Foxes, rabbits, deers and wild boars can also be seen.
