The Kattasay and Daganasay Reservoirs Important Bird Area ( Russian: Водохранилища Каттасай и Даганасай, Chinese: 卡塔赛和达嘎纳赛水库重点鸟区) comprises two irrigation reservoirs and their surrounds in central Sughd Province in northwestern Tajikistan. Together, they have been identified as a 98 square kilometres (38 sq mi) Important Bird Area (IBA) by BirdLife International. [1]
Description
The IBA is situated on the northern slopes of the Turkestan Range. Daganasay lies some 16 km north-east of Kattasay at a similar altitude of about 1,200 metres (3,900 ft) above sea level. Both reservoirs are oligotrophic. The area has a semi-arid climate with warm summers and mild winters. Annual rainfall is about 400 millimetres (16 in), mainly in spring. [1]
The IBA lies on the Central Asian Flyway and its characteristics of low disturbance, plenty of food and a mild climate attract birds. It is used by migrating waterfowl in autumn and spring, while various species of waterbirds, waders and birds of prey also overwinter there. [1]
Daganasay Reservoir
Daganasay ( 39°54′10″N 69°08′45″E / 39.90278°N 69.14583°E) lies 9 kilometres (5.6 mi) to the south of the town of Ghonchi. It has a surface area of 280 hectares (690 acres) when full, a volume of 42 GL and a maximum depth of 18 metres (59 ft). Towards the end of the irrigation season its area is reduced to 35–40 hectares (86–99 acres) and the depth to 3 metres (9.8 ft). Some 132 species of algae have been recorded. [1]
Kattasay Reservoir
Kattasay ( 39°50′30″N 68°59′35″E / 39.84167°N 68.99306°E) lies in the Istravshanskaya depression. When full it has an area of 290 hectares (720 acres), a volume of 55 GL and a depth near the dam of 45–48 metres (148–157 ft), falling to a minimum of 18 metres (59 ft). The main source of its water is the small Kattasay River. [1]
Birds
Birds for which the site is important include saker falcons, solitary snipe, European rollers, Hume's larks, sulphur-bellied warblers, wallcreepers, brown accentors, water pipits, fire-fronted serins, crimson-winged finches, red-mantled rosefinches and white-winged grosbeaks. [1]
