For characterisation of vegetation extensive uptakes and a areawide mapping of vegetation units were carried out. Faunistic studies concentrated mainly on bird fauna. As natural vegetation of the “percolation”-surface flow mires extensive sedge fens of different associations, dominated by Carex otrubae and C. orbicularis were found. Through erosion of the mire surface, a secondary immigration of Phragmites australis occurs. As a result of intensive grazing, a rapid degradation of the natural sedge vegetation and a replacement with Carex divisa-communities takes place. At the same time, plant species of alpine origin invade in the mire vegetation. In contrast to this, terrestrialisation mires are inhabited by communities with sedges, Equisetum ramosissimum, Schoenus nigrigans and Typha. Specific for paludification mires in subarea two is a eutrophic Bidens-Carex community. On peaty soils, a Carex songorica community was observed. Furthermore, the studied mires are naturally wood-free. Most plant communities of the studied mires were not described before and are partially only known from the study area. The plant species composition show most analogies with those from mires in Siberia. The vertebrate fauna of the studied mires is relatively poor in species. Only one reptile, three amphibians, 30 breeding bird species and a few fishes and mammals live in the mires and adjacent wetlands. Much more bird species can be found during migration and as feeding guests (176 bird species in the whole valley). Faunistically important are findings of two globally threatened bird species and six bird species on the Kyrgyzh Red list.}, note = { \url {http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/7374}}, }
