encompassing the following
In the 1970s and mainly 1980s, the large scale regulation of water regime in the landscape was carried out over the whole country (at that time it was Czechoslovakia). The purpose was to increase self-sufficiency in agricultural production, which was desired by the communistic government. As a part of this effort (in many cases not cost beneficial), the water regime of Borova brook and its catchment area were also regulated.
In a large-scale drainage project (done in 1982-1984), the orginal meandering stream of the Borova brook was straightened and reduced. The stream bed was over deepened to a depth of 1.2-1.8m and stregthened by concrete blocks. At the same time, argricultural land in the catchment area (17.8 km2)of the brook was drained. The result of the intervention was a serious disturbance of the water regime in the whole catchment area and led to the degradation and decline of natural and semi-natural communities
The restration was undertaken in two phases. During the restoratio the length of the stream increased by 6.3 km. A shallow meandering streambed, where sections of speedily running water alternated with sections of a slow stream were created. The project was fully funded from the program for revitalization of river systems by the minitry of Environment.
Monitoring surveys and results
Invertebrate within the wet habitats of the brook valley responded positively to the restoration. There was an increase in diversity following the works.
The stream provided flood storage during the 2001 flooding.
