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.

Design capacity description
Increased the total length of the stream 6.3 km
Constraints
The drainage tubing at the surrounding pastures had to remain undisturbed except for the spring area where a small wetland was established.
Favourable preconditions
It was a former meanders channel which was straightened in the 70s

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.

Information on Ecosystem improved biodiversity
Results show that the macroinvertebrate assemblage of the restored section of a small stream contained higher species richness in comparison to channelized conditions that preceded the restoration, especially prominent shortly after the restoration intervention. However, the restoration did not increase abundances of rare Ephemeroptera and Plecoptera species.
