Site description The Angren plateau is situated at the head of the Akhangaran river in the Western Tien Shan. It connects Kuramin ridge with Chatkal ridge. There is an extremely difficult to access canyon with well developed tugay forests on the plateau. The proposed IBA includes the head of Ikkisu river which flows across the Angren plateau.

Key Biodiversity A unique mix of mountain and plain species live on the alpine Angren plateau. Passersines form the majority of this community: Eremophila alpestris, Calandrella acutirostris, Oenanthe isabellina, Monticola saхatilis, Phoenicurus ochruros, Prunella fulvescens, Prunella himalayana, Prunella collaris, Phylloscopus griseolus, Leucosticte nemoricola, Petronia petronia, Montifringilla nivalis, Bucanetes githagineus and Corvus corax tibetanus are all numerous. Raptors are numerous among the non-passerine species: Falco cherrug, Falco pelegrinoides, Falco subbuteo, Buteo rufinus, Aquila chrysaetos, Aegypius monachus, Gyps fulvus, Gyps himalayensis and Gypaetus barbatus. These species breed on the cliffs and canyons that surround the plateau. During summer immature and non-breeding birds of these species are also present. The disappearing mountain subspecies of Bubo bubo breeds on the cliffs of the plateau. The area is very important for bird migration during early autumn. Heavy passage was observed at a height of 3,000 metres (observation O.V. Mitropolskiy)involving Aquila clanga, Falco naumanni, Circus macrourus, Pernis рtilorhyncus and Calandrella cinerea. In winter Tetraogallus himalayensis is observed routinely in rocky habitats.

Non-bird biodiversity: One of the largest colonies of Marmota menzbieri (endemic to the Western Tien Shan) inhabits the Angren plateau but currently its size in depleted. The rodent fauna is unique with Spermophilus pygmaeus, Microtus kirgisorum, Microtus juldaschi, Alticola argentatus and Cricetulus migratorius. Ursus arctos isabellinus occurs in very low numbers. Vormela peregusna, Cuon alpinus and Capra sibirica are also present. There are also numerous endemic species of flora and invertebrates.

IBA Monitoring

2006 very high not assessed negligible
Good - based on reliable and complete / representative data

Agriculture and aquaculture livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming happening now whole area/population (>90%) moderate to rapid deterioration very high
Biological resource use hunting & collecting terrestrial animals - unintentional effects (species is not the target) happening now majority/most of area/population (50-90%) slow but significant deterioration high
Energy production and mining mining and quarrying past (and unlikely to return) and no longer limiting some of area/population (10-49%) moderate to rapid deterioration low

Little/none of site covered (<10%)  No management plan exists but the management planning process has begun  Unknown  negligible

Protection status The Angren plateau is not a protected area but the Akhangaran canyon is part of a game-reserve where licensed hunting of mountain goats and wild boars is permitted.
