Аннотация:Collection of samples was carried near river Kuzha in nature reserve Shulgan-Tash by Laboratory of animal ecology and biomonitoring EFA in year 2017. In course of research, 20 taxons of macroinvertebrates of river Kuzha were determined: Ephemeroptera (dayfly), Plecoptera (stonefly) both in larval stage, which are the significant indicators of eutrophication level. Preliminary conclusion was made: life-sustaining activity of European beaver is making noticeable difference in life-sustaining activity of zoobenthos, even though beavers habitat development is low in this area, thus increasing percent of nonrheophilic species.
