The monitoring survey of environmental elements, the biological quality of aquatic habitats has initially been assessed as a starting state, then as a period with human impact and finally as a stage of revitalization of the impaired territory. The qualitative and quantitative monitoring thus indicates the developmental process of the aquatic biota in mountain ecosystems. The biosurvey of the changes in aquatic habitats was carried out on amphibians as the model species. These find here attractive habitats and provide satisfactory indications of human impact. The results represent data collected from the regions: Malá Fatra, Velká Fatra, Slovenský Raj, Spišská Magura, Oravská Magura, the western part of Slovenské Rudohorie, a part of the High and of the West Tatras.
