Topic of the practice

The project has brought innovative methods for the area through the development of green infrastructure. Heart of the project was the construction of a dam with a sluice on the Neajlov River, downstream of Comana Lake. Its purpose is to increase and maintain a constant level of water in the floodplain area.

Good Practice Information

The depth in the river area increased by more than 1.50 m, which has extended the water surface to 490 ha and maintain a considerable area of shallow water with depths below 0.50 m. To achieve the results works were conducted for water volume control in the area of biodiversity interest. In the sluice area, downstream of the dam a fish scale has been projected and built in order to avoid
aquatic habitat fragmentation and disruption of the migration route of some species of fish. It also helped to recreate feeding and breeding habitats for fish and birds. For fish populations and their invertebrate prey, the new conditions such as oxygen concentrations, changing water levels and their daily fluctuations have improved the quality of habitats and species richness.

Evidence of success

Project implies the implementation of first monitoring system of environmental parameters and bird species in the region and has diversity of activities as implement of innovative green infrastructure for the area. It is estimated that the habitat for bird species was improved on the surface of minimum 30% of initial surface of Comana wetland and the number of birds increased by at least 5%.
