Project summary

Edit project overview to modify the project summary.

The aim of the project was to connecting agricultural polder Fortuna (2,115 ha) to the Danube regime. Restoration of hydrological regime and hydrological functions means for this area, restoring and establishing the following functions: - habitat for plants and animals typical alluvial areas; - habitat and breeding area for fish and aquatic birds; - reservoir for biodiversity and providing genetic resources; - biocoridor and genetic exchange; - organic production; - biogeochemical circuit elements; - retention of sediments and pollutions; - Black Sea biofilter
