Boulder ramps as a restoration measure: Increasing in the resilience of mountain freshwater ecosystems to environmental changes.

Mountain environments, as biodiversity hotspots, are subject to numerous anthropological pressures. In mountain areas, a common threat to stream biocenoses is the timber industry. Timber industry increases the fine sediment input into the mountain rivers; furthermore, timber transport requires the construction of low-water crossings across streams.

Assessment of the viable effects of structural reconstruction of habitats in a mountain stream: A long-term study.

The Carpathians are biodiversity hotspots in Europe. However, transformations resulting from human activity have affected stream catchments where forest management is carried out. Numerous anti-rubble weirs and other low-head barriers disrupt the continuity of many streams.
