Site description Karakyr lake system is situated in the SW Kyzylkum desert 30 km to the N of Gazly town and 120 km to the NW of Bukhara town. Nearby there are some large hills with the same name. Karakyr was created in the 1970s and consists of two large wastewater lakes and a large area of floodplain located along the collector channel supplying the lakes. The lakes have open water areas surrounded by reed. Seepage and flooding of the sandy desert surrounding the lakes and floods is resulting in the growth of grassy vegetation and the sands are becoming fixed. The water supply of lakes is excess water from the Northern collector. The main period of inflows is in March-April. Karakyr lakes system consists of three separate lakes: Big Karakyr, Small Karakyr and Aquarium. The general area (with a buffer zone) is about 50,000 ha. The maximal depth is 4.0-5.0 m (10-15 % of all area), the average depth is 2.3-3.0 m (65-75 %). In summer due to the high rate of evaporation and a reduction of water inflows most of the reservoir (40-50 %) dries up and there is eutrophication. The bottom of the lake is basically firm but there are oozy sediments in some areas. The general mineralization is rather high: from 5,360 mg/l in winter-spring up to 12,842 mg/l in summer-autumn. Although only a few sites have been formally proposed under the A3 biome-restricted criteria (for biome CA04b Eurasian Desert and Semi-desert), many of the IBAs in the Kyzylkum Desert region support populations of biome-restricted species and, effectively, form a network of sites throughout the area.

Key Biodiversity The avifauna of Karakyr is typical of similar ecosystems of the region. According to literature data and our own observations about 200 species of birds have been recorded at the site. Of these 122 species are waterfowl and waterbirds. Typical and numerous species are Podiceps nigricolis, Podiceps cristatus, Anser anser, Netta rufina and Circus aeruginosus. Porzana parva, Gallinula chloropus and Fulica atra nest throughout. On the shore Vanechettusia leucura, Himantopus himantopus and Glareola pratincola breed. In the reeds Acrocephalus stentoreus, A.agricola, Locustella luscinoides, Panurus biarmicus etc occur (Sagitov, Pukinskiy, Pukinskaya, 1989). According to the same authors, nesting of Glareola nordmani has been suspected but we have not found this species during repeated visits to the wetland at the end of the 1990s. In 1987 (on April 19) just in the area of the Aquarium a colony consisting of approximately 1,000 nests of Phalacrocorax carbo, 41 nests of P.pygmeus, 400 pairs of Nycticorax nycticorax, 15 pairs of Ardea cinerea, 3 pairs of A.purpurea was found. 8-10 individual Pelecanus crispus and P.onocrotalus have also been noted but nests have not been found plus Egretta alba, E.garzetta, Plegadis falcinelus and Platalea leucorodia. In an area of 8 ha 4 male Botaurus stellaris were displaying. Typical species of the islands and shore of the reservoir and nearby saline soils are: Charadrius dubius, Charadrius alexandrinus, Vanellochettusia leucura, Himantopus himantopus, Recurvirostra avosetta and other waders, also Glareola pratincola, Sterna hirundo, Sterna albifrons and Larus cachinnans. On wet sites near to the lakes and overgrown with tamarix, reed and other vegetation, breeding birds include: Panurus biarmicus, Hippolais rama, Acrocephalus stentoreus, Acrосephalus agriсola, Emberiza schoeniclus and Corvus corone. The following species are most typical of the desert around the lake: Burhinus oedicnemus, Podoces panderi, Pterocles orientalis, Caprimulgus aegyptius, Galerida cristata, Merops superciliosus, wheatears, Sylvia nana, Hippolais rama and Rhodospiza obsoleta. Chlamуdotis undulata also nests here. In June 1998 and 2000 in the depressions among the hilly areas we regularly observed broods of this species. Winter counts of the lakes have recorded 43 species of bird. The data of these counts are given below. List of wintering birds: 1. Tachybaptus ruficollis 2. Podiceps cristatus 3.

Non-bird biodiversity: Various mammals occur in the adjacent desert including Gazella subgutturosa (included in the Uzbekistan Red Data Book). Huntable species include Lepus tolai and Sus scrofa. Vulpes corsac, Felis chaus and Felis libyca also occur. Rodents are represented by gerbils and jerboas. Introduced species include Ondatra zibethicus and Myocastor сoypus. Of reptiles Varanus griseus and Teratoscincus scincus are included in the Uzbekistan Red Data Book. There are also various lizards, agamas and Trapelus sanguinolentus. In the lakes Barbus capito conocephalus, Cyprinus carpio, Silurus glanis, Stizostedion lucioperca and other fish can be found. Rana ridibunda and Bufo viridis are numerous. Zooplankton in the lakes includes 15 species. In shallow water areas reed is common. There are Potamogeton sp., on the shore thickets of tamarix. In the sandy desert characteristic vegetative associations consist of bushes of saxaul and sandy acacia.
