All partners agreed to continue the project Conclusions After a slow start a successful trans-national collaboration was established General strategy: Harmonize the project goal (common report, common maps) But no harmonization on how to achieve it Discussion, negotiation for boundary water bodies Some of the results (methods) are used within the Odra and Wistula catchment All partners agreed to continue the project
