Central coordinates 73o 0.59' East  37o 50.07' North
IBA criteria A1, A3, A4i
Area 149,590 ha
Altitude 3,239 - 5,679m
Year of IBA assessment 2006

Site description The IBA is 220 km from Khorog town. The area has a very complicated topography and its mountain belts are defined by altitude. There are mainly gently slopes and vast highland valleys with sparse vegetation. To the north of the water basins there are mountain ranges with large areas of scree. The largest gorges in the north of the IBA are Kichik, Marjanay and Okjilga. Rivers of the same name flow into lake Yashilkul. The central part of the IBA is two freshwater lakes, Yashilkul and Bulunkul, with a surrounding plain which contains marshes, wet meadows, peatbogs and medium-sized pebble and sand plains. The open water area of lake Yashilkul is 3,600 hectares with a maximum depth of 52 m. The area of lake Bulunkul is 3,900 ha with a maximum depth of 6 m. This lake has dense vegetation cover over its surface but Yashilkul, as a result of its significant depth, only has vegetation on part of its surface. The boundary between Pamir and Badakhshan is situated near lake Yashilkul.

Other biodiversity Fish: 6 species recorded - Schizopygopsis stoliczkai, Schizothorax intermedius and Nemachilus stoliczcai are native species. In the 1970-80s young fish and larvae of Salmo ischchan, Carassius auratus and Coregonus peled were introduced to Yashilkul and Bulunkul lakes. Of these only Salmo ischchan became established. Amphibia and reptilia: as a result of the inclement climate of Pamir there is only one species Bufo viridis and reptiles are completely absent. Mammals: Rodents are represented by Marmota caudata, Microtus juldaschi and Alticola argentatus. Leporidae are Lepus tolai and Ochotona roylei [macrotis]. Wide valleys and gentle slopes are habitats of Ovis ammon polii, and rocky slopes of Capra sibirica. Carnivora are Ursus arctos, Uncia uncia, Felis manul, Canis lupus, Vulpes vulpes, Mustela nivalis, Mustela erminea and Lutra lutra. Ovis ammon polii, Ursus arctos, Uncia uncia, Felis manul and Lutra lutra are included in the National Red Data Book. The vegetation of the IBA consists of desert associations. As in Pamir there are 4 main mountain belts. A small nival belt on the southern Alychur Ridge at an altitude of more than 4,800 m above sea level, with very sparse vegetation. Melandrium apetalum, Cerastium cerastoides, Ajania tibetica, Oxitropis immersa, Sibbaldia tetranda and other species are resistant to intensely cold weather. High-alpine and low-alpine belts are situated between 4,200 and 4,800 m above sea level and in most dry habitats the dominant sub-shrub is Ajania tibetica. In the more wet areas typical species are the frost resistant Oxitropis immersa, Oxitropis poncinsii and Smelovskia calycina. In the lower alpine belt desert formations are typical, with dominant species being Krascheninnikovia ceratoides, Artemisia skorniakowii and Ajania tibetica (Stanyukovich, 1949). Almost the same type of vegetation is in the subalpine belt. In the marshes perennial wild gramineous plants grow. Dominant among them are Stipa orientalis, Alopecurus mucronatus, Trisetum spicatum, Poa calliopsis, Poa pamirica, Poa relaxa, Poa tremuloides, Poa litwinowiana, Puccinellia hackeliana, Puccinellia humilis, Puccinellia pamirica and others.
