General National Id Czech_06 Site name Borova Stream, south-western part of the "Blanskí Les" Protected Landscape area, 5 km north-western from the Chvalšiny village Summary Restoration of the length of the Borova stream, increased by 6.3 km a shallow meandering stream bed, where sections of speedily running water alternated with sections of a slow stream were created, financed by the Ministry of Environment of Czech Republic.

Key lessons Morphologically degraded stream sections are typically characterized by low habitat heterogeneity and consequently lower biodiversity compared to more natural sections. These measures certainly increase morphological heterogeneity and mimic the pre-disturbance state. On the other hand, the intervention included substantial disturbance and the use of heavy technique which have seriously affected the biota.

However, the restoration did not increase abundances of rare Ephemeroptera and Plecoptera species.
