Site description The IBA is situated in the southwestern part of the Kyzylkum Desert and includes Lake Tudakul, a small swamp and Kuyu-Mazar Reservoir. Lake Tudakul is situated 23 km NE of the town of Bukhara and Kuyu-Mazar Reservoir 1 km NW of Tudakul. The water in Tudakul is saline. Kuyu-Mazar Reservoir was created to provide the areas situated in the arid zone with drinking water. the western and northern parts of Lake Tudakul are free of any shoreline vegetation; the south and eastern parts are overgrown with reeds and tamarisk, from 10-15 to 150-200 m in width. The lake is more or less spherical, its average width is 30 km, average depth reaches 5-8 m. The western part of the lake has a high and precipitous coast. Beyond it is a marshland with isolated waterbodies surrounded with reed. Several open islets rise in the central and northern parts of the marshland. The water is the reservoir is fresh. High islets and promontories occur in the central and northern parts, which shelter cormorants, gulls and birds of prey. The shores are mainly stony and precipitous; they are practically free of vegetation. Flat coasts are overgrown with halophytes and saltwort. 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.

Other biodiversity The following mammals have been recorded: Vulpes vulpes, Vulpes corsac, Felis lybica, Mustela eversmanni, Vormela peregusna, Meles meles; of rodents, Rhombomys opimus, Meriones tamariscinus, Ellobius tancrei, Nesokia indica, Allactaga elater, A. severtzovi and Spermophilus fulvus are resident; Lepus tolai and Hemiechinus auritus are common. In recent years, the introduced Ondatra zibetica and Myocastor coypus have been noted. Amphibians are represented by Rana ridibundus and Bufo viridis. Reptiles are represented by Agrionemys horsfieldi, Natrix tesselata, Coluber karelini, C. ravergieri, Erix miliaris, Psammophis lineolatum, Phrynocephalus helioscopus, Phrynocephalus interscapularis, Eremias lineolata, Eremias scripta, Trapelus sanguinolentus, Cyrtopodion caspius and Teratoscincus scincus. The fish fauna is comprised of 10 species. The flora has not been studied in detail, but it includes species typical of wet parts of the desert areas of Bukhara.

Protection status Currently, only one water protection zone of the Kuyu-Mazar Reservoir is protected. It is of importance as a source of fresh drinking water and roosting area of migratory and wintering birds. It is necessary to create an ornithological reserve on the Kuyu-Mazar Reservoir and beyond the dam of Lake Tudakul, on the marshy area which is the breeding ground of Marmaronetta angustirostris, Aythya nyroca and Oxyura leucocephala. For Lake Tudakul, it is necessary to develop a management plan for coordinated use of the area. The majority of the wintering and migrating birds is concentrated in the territory of the hunting farms.
