The ornithological diversity of fields around the pool is home to over 280 species of birds, mostly migratory birds that fly over this part of the Adriatic Sea on its long overflights to wintering grounds, particularly in Africa or in the Mediterranean, and there is a smaller number of two rare and endangered species which nest in the salt pans.
From waterfowl most popular are: stilt, little egret, kentish plover and kingfisher. Stilt (Himantopus himantopus) is a bird that usually lays four eggs characterized by black dots. The reason for the choice of habitat for these birds crab slaništar that food. Stilt captivates with its appearance black-colored back and wings and white belly and neck, long, thin, red legs. Stilt are very sociable. Outside the nesting season are retained in small flocks, usually 5-10 birds together, and often engage in mixed flocks.
Kentish plover (Charadrius alexandrinus) is smaller bird species, relative of stilt which is today unfortunately becoming scarcer and, according to the Red Book of endangered birds of Croatia, it belongs to endangered species.
Of the many species of birds on the salt fields of Nin we can observe: oystercatcher (Haematopus ostralegus), stone curlew (Burhinus oedicnemus), jewelers plovers (Pluvialis squatarola), common redshank (Tringa totanus), curlew sandpiper (Tringa nebularia), curlew (Numenius arquata ), black-tailed godwit (Limosa limosa), curlew sandpiper (Calidris ferruginea), little stint (C. minutes), dunlin (C. alpina). Occasionally, a smaller number of flies observed even eclipse spotted redshank (Tringa erythropus), plover (Charadrius dubius), common ringed plover (Charadrius hiaticula), golden plover (Pluvialis apricaria), pied avocet (Recurvirostra avosetta), tailed godwit (Limosa lapponica).
Among the other species of birds on the salt pans in water pool can see little egret (Egretta garzetta), gray heron (Ardea cinerea), various species of ducks such as mallards (Anas platyrhynchos), wigeon (A. penelope), pintail (A . acuta), ducks teal (A. crecca), gadwall (A. querquedula) and others. The ducks can be seen little Grebe (Tachybaptus ruficollis), great crested grebe (Podiceps cristatus), red necked grebe (P. grisegena) and black-necked weaver (P. nigricollis). Particularly remarkable du to its colors is the kingfisher (Alcedo atthis) and european bee-eater (Merops apiaster).
Mediterranean killifish, only 3 cm long, lives in the first two phases of the evaporating pans and is considered an endangered species because of the disappearance of suitable habitats. What is also interesting unique tiny brine shrimp which is remarkably well adjusted to life in extremely salty water, but also the survival of drought. His eggs are in the mud and can survive without moisture for even 10 years. They can only be visibl under the microscope.
At the park of the Nin Saltworks you can see interesting plant species that have adapted to the specific conditions of this wetland area.
Halophyte plant covers our evaporation ponds, and is known as the herb of which flamingos get a pink color. It can only be found in the sea with black peloids from which it directly absorbs minerals and is very healthy and tasty; it can be used as a salad dressing.
The Adriatic sea
The Adriatic Sea along the Croatian coast stands out with the distinct transparency and intense color, which along with the picturesque coastline contributes to the unique landscape. Thanks to the high quality and the absence of industrial environmental impacts, the Adriatic sea is one of the cleanest seas in the world. Thanks to that, it is possible to get the highest quality sea salt from it. Adriatic Sea, with its remarkable diversity of indigenous plant and animal species represents a harmonious ecosystem and pristine natural treasure of Croatia.
It abounds with mineral salts, plankton and algae in which water changes for 5-10 years, while in the Mediterranean Sea takes 70-100 years for water changes.
Scientific studies have shown that the Adriatic Sea contains over 80 essential minerals and trace elements essential for human health. The UN has declared the Adriatic sea an ecosystem of special attention. An important property of seawater is saltiness, or salinity, which expresses the total quantity of dissolved salts in 1000g of seawater. The salinity of Adriatic sea is high – an average of 38.30 parts per thousand, ie. one kilogram of water dissolved 38.30 g of salt.
It is very important natural phenomenon because it significantly affects the lives of people, organisms and vegetation. Bora is created when the cool air from the hinterland of Lika crashes down the steep slopes of Velebit mountain range and the narrow coastal bay towards sea. Bora is a frequent visitor of the Nin Saltworks.
Bora is a strong cold wind which is blowing from the area in which there is no industry. Therefore, it is extremely clean and healthy. Along with the sun, it helps the speed and naturalness of with which salt is produced.
Confirmation of purity and unaffectedness of the climate comes from the fact that the Nin Saltworks is located in the heart of five Croatian national parks (Plitvice, Paklenica, Kornati, North Velebit and Krka.)
On the territory of Nin there is a site healing mud (peloid), type liman. The Nin peloid has been used for medical purposes since the Roman period, possibly even earlier, to this day. It is proved by the installation of fragments typical for Roman spa. In 1954 a mechanical composition analysis of the peloids in Nin has been performed. Thanks to this analysis, it became evident that it is the Croatian site of highest quality.
Such mud is formed in calm, shallow sea lagoons in which a river or a stream flows. In the making of the pond, substances brought by the terrestrial freshwater and sea. In developing the liman there are three phases. During the first phase, rainwater washes away the substance off the coast. These are mainly minerals and smaller organic substances caused by the disintegration of land flora and fauna. In the second sea phase, the sea floods the river estuary and the organic remains, along with some mineral substances sink to the bottom. Nin Saltworks was made at that stage of development of the liman. The muddy areas of the liman are used for the treatment and are considered healthy mud because they are filled with a variety of minerals. During the production of salt, these minerals enter the salt, giving it special flavor and properties. The quality of the sea and the geological substrate on which the salt pan is built give the salt special chemical composition, while the sea and the wind are making the process of production unique.
The Nin Saltworks is built in the area of healing mud, rich with minerals which contributes to the high quality of the Nin salt.
