The article deals with the naturalization processes occurring in the regulated stream beds. It was found that naturalization processes are influenced mostly by the prevalence of herbaceous and woody vegetation in regulated streams. 34 species of woody vegetation were found in analyzed streams. The most common among found types were sallow (Salix caprea L.) and shrubs (Salix Ciner L.). The overall density of the woody vegetation, growing on the slopes of streams, reaches T = 1.26 ± 0.20 pc./m2. The strong dependence of the woody vegetation habitats density on the distance to the forest (correlation coefficient 0.70 to 0.90) was received. Both woody and grass vegetation seems to have the same impact in reducing the nitrate ion concentration in the water self-purification.

Keywords: regulated streams; naturalization; vegetation; nitrates.
