Measures and Methods

• 30 Integrated Buffer Zones (IBZ)
• 2 Level Wetlands (LW)
• 6 Optimized Constructed Wetlands (OCW)
• 60 Creotopes (created biotopes) incl. 30 amphibian ponds
• 500 nest boxes (birds, bats and insects)
• 1 Bio-passage in the stream (removal of migration barrier)
• 1 Urban Storm Water Pond (USP) + modification of pipes
• 1 Field Information Center + demonstration sites

Our methods

• Close co-operation with landowners
• Voluntary participation
• Focus on landowner families
• All facilities are 100 % financed by the project
• Contracting with experienced construction companies
• Surveys and investigations before and after the project (nutrients, floods, biodiversity)
• Results presented on website, mail-lists, national meetings, international conferences

Expected results

• Good Ecological Status in river Trönningeån
• P-concentrations in the stream reduced to < 50 µg/l
• Migration possible in the whole stream
• 10 % increase in Salmonid density
• Reduced flood risk in the village of Trönninge by 20 %
• Increased biodiversity in the catchment
• Calculations showing economic cost-effectiveness
• Quantified carbon sequestration in IBZs and LWs
• Improved conditions also in the Natura 2000-river Fylleån
• The concept have been presented at 4 international conferences in the EU and in 1 scientific paper.
• Long-term goal: the concept is implemented throughout EU
