Site description The IBA is located in the north-eastern part of Turkmenistan in the Birata district of the Lebap region. The site includes lakes, a system of water reservoirs (Duyeboyun, Soltansanjar and Koshbulak), part of the Amudarya river (68 km in length), the Duyeboyun reservoir floods and lakes, and adjoining parts of the Pitnyakskaya uplands with patches of sandy and stony-clayey desert and saline depressions. Young tugai forests are present along the Amudarya at Syuduktugay, Saduar and Hanyan and appeared after filling of the Duyeboyun reservoir. Meadows, alluvial soils and saline depressions occur in the Amudarya river valley. The average monthly air temperature in June is +32C, in January -2C. The absolute maximum is +47C and minimum is -31C. Less than 100 mm of precipitation falls per year. Northern and north-eastern winds dominate (Orlovsky, 1984). The reservoirs and floods freeze if winters are unusually cold. There are no settlements in the site, but there are huts for fishmen and shepherds. Biratinsky district is a border zone and the river Amudarya is the border between Turkmenistan and Uzbekistan. As a result part of site is under military control. The proportions of land and water change due to water level fluctuations.

Other biodiversity Two species of Amphibia (Bufo viridis and Rana ridibunda), 17 species of Reptilia, among which Varanus griseus and Phrynocephalus rossikowi are included in the National Red Data book, occur. Mammals total 30 species: Insectivora - 3, Chiroptera – 4, Lagomorpha – 1, Rodentia – 16, Carnivora – 5, Ungulata – 1. Hystrix indica, Allactaga bobrinskii and Jaculus turcmenicus are included in the National Red Data book. Psammophytes and miscellaneous ephemeral herbs are the dominant species of which is Carex physodes is the most widespread. Bushes include Haloxylon, Calligonum, Salsola richteri, and Epherda. In some places there is Artemisia and Salsola. Forest/bush tugai vegetation consists of Populus, Elaeagnus, Tamarix, Halimodendron and Halostachys caspica. On the unflooded or occasionally flooded parts of the tugai thickets of reed, Glycyrrhiza, Calamagrostis, Trachomitum scabrum and Aeluropus grow.
