The area of the Zolbin wetland is about 10 hectares, which in a relatively small amount of years decreases in size and is often converted into landfill. The height of this ocean lagoon is about 1,650 meters long, which is not much depth at the eastern side.
Among the most important birds in Zolbin Wetland, we can mention dwarf crests, duck duck, oak duck, lush duck, black crested neck, small crayfish, bootyram and wet cesium. In addition to the Zadavar species, a number of migratory passers-by-boaters will also enjoy nutrition and rest on their thousands of kilometers from the north to the south of the wetland. Due to the existence of wheat and meadow fields around Zolbin wetland, the gray goose is a migratory wetland as a migratory and passive bird longer than other species.
A little depth of the Zolbin wetland in its eastern part provided the opportunity for the growth of roots in the waters such as Nay and Levy, and there were massive havens in the eastern and southern parts of the wetland, which are a safe haven for birds and their laying. The depth of the lagoon water in the vegetation zones is on average 1.5 to 2 meters, and in the northwest of the deep area there are drainage of groundwater from this part of the wetland as a spring. The catchment area of the Zolbin wetland is about 500 hectares, with no significant surface water flooding.
The main sources of water supply in Zolbin wetland are underground caverns and crustal streams due to atmospheric precipitation in different seasons of the year. In years of water deficit or drought, the water level of the wetland has fallen sharply and with the coastline retreat, The Nizarahs of the eastern part of the water come out of the water. In such a case, aquatic birds have left the habitat of the wetland due to the vulnerability of the lagoon, and a few are found in the middle part of the lagoon, which is more in depth than its other parts. The beauty of the wetland is not limited to beautiful birds, but the western area covered with grass, which extends from the beach to the coastline, creates a pleasant atmosphere for wildlife.
In the combination of vegetation on the coasts of the Zolbin Wetland, a tree or shrub whether wild or planted by the people of the area can be observed, and in addition, rooted plants in the water make up the vegetation within it. Nay, Levy, Pelignum Amphibioum, Husab and Isma Gramineum are major vegetation in the wetland wetlands, which often have roots in the water or are immersed in its glacial water. The vast majority of the coastline of the lagoon is a massive lagoon, which plays a vital role in the nesting and securing of aquatic and parasite birds. In spite of the dreams of the Zolbin wetland in the high season of the year, such as the spring of human use, it has harmful effects and in some cases it is irreversible.
Zolbin wetland is rich in food, and its water color changes in the warm seasons due to the flooding of plankton and algae. This wetland is known as one of the three wetlands of the ducks' redevelopment site as an endangered species in the country along with the glacial lagoon and Yaniq wetlands. Also, the survival and rejuvenation of the duck and dwarf oak as essential animal species in Zolbin wetland make it necessary to protect it. In spite of its strategic importance in preservation of endangered species, this wetland has no status and is considered as free zone in terms of the legal status of the areas under management of environmental protection of the East Azarbaijan.
The lack of a legal definition for protecting this unique wetland has led to the use of animal species in permitted seasons by hunters. Zolbin wetland also faces destructive factors that direct water pumping for irrigation of nearby farms, penetration of livestock and cutting of nizzas as habitats and breeding grounds of birds, introduction of sediments due to plowing landslides adjacent to the lagoon and entering sewage and Chemical wastes are among them. It is hoped that in the light of the interaction of the people of the region and the principled and scientific management of the Hashrtrood Environmental Protection Agency, the extent of the Zolbin wetland as one of the natural resources of the region will be prevented.
