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
