Özet:

This study was carried out in July 2016 in Camili (Macahel) which is Turkey's first and only biosphere reserve area. The aims of this study were to investigate the Simuliidae species of some streams in Camili Valley, to identify the “reference site” which are important for Water Framework Directive (WFD), to determine ecological characteristics of the studied sites according to System A and System B Classification of Water Framework Directive (WFD), to explore the relationship between the recorded species and some environmental variables of streams by using CCA technique. For this purpose, 257 individuals of Simuliidae were sampled from nine studied sites. Physicochemical variables (dissolved oxygen, pH, water temperature, electrical conductivity, velocity) were measured at each studied site. In Camili Valley the following species were collected: Simulium (Nevermannia) angustitarse, Simulium (Nevermannia) cryophilum, Simulium (Nevermannia) vernum, Simulium (Simulium) bezzii, Simulium (Simulium) tuberosum, Simulium (Simulium) variegatum. Because anthropogenic stresses were insignificant in the research area, studied sites and Simuliidae fauna of the area were not affected negatively. Also, six of studied sites have reference habitat conditions.
