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.
Today this project is still relevant and effective, although it would need reconstruction in places.

Project's objectives
the complex revitalization of Borová Stream basin including:
- renewal of the natural character of the stream as well as renewal of its original function
- increasing the accumulative possibilities of the land and retarding the surface water, flood protection
run-off
- increasing the variety of species
- dividing the area into smaller sections by planting alleys and groups of greenery

cancellation of the old regulated stream bed and creation of a natural meandering stream
Design capacity description
Increased the total length of the stream 6.3 km
The project benefited as much as possible from the specificities of the basin.
The drainage tubing at the surrounding pastures had to remain undisturbed except for the spring area where a small wetland was established.
It was a former meanders channel which was straightened in the 70s

Comparison of composition of macro-invertebrate samples focusing on species richness, species composition, and representation of rare Ephemeroptera and Plecoptera species
In 2008, an exhaustive study of the geological, hydrogeological, hydrobiological, entomological, zoological, botanical and landscaping aspects of the revitalized Borová stream was conducted and a comparison was made with the state in 1995 (before the revitalization)

Maintenance
Management and maintenance are carried out by the stream administrator - the state organization Forests of the Czech Republic.
Catchment outlet
Benthic macroinvertebrates were sampled using the semiquantitative kick and sweep technique and by hand-picking of specimens from stones and macrophytes.
Stream increased by 6.3 km alternated with sections of slow stream
Information on retained water
The stream provide enogh flood storage during the flooding time
Information on increased water storage

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.

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.
