Eight kilometres south of Rovinj on an area of about 20 hectares in the rainy periods and two hectares in periods of drought, near the sea and the bays Cisterna and Gustinja, it is located the only ornithological reserve in Istria, the "Special ornithological reserve Palud - Palù" whose trademark is the Water Rail (Rallus aquaticus).
Palud was a freshwater swamp that the Austro-Hungarian army connected to the sea in 1906 by digging a channel with the hope that the increased salinity of water would stop the development of mosquito larvae and thus prevent malaria. They didn't manage to suppress malaria but as a result of the mixing of fresh and saltwater in the swamp, mullets and eels, fish that prefer brackish water, found their habitat.
