  2. THE BOTHNIAN BAY – LOCATION The Bothnian Bay The Baltic Sea

  3. THE BOTHNIAN BAY - PROBLEMS • Environmental problems • signs of eutrophication • metals in sediment • high dioxin levels in fish • reproduction problems Sensitive sea area • low water temperature • brackish water • low number of species • simple food webs Environmental management and monitoring shared by two countries Environmental data and information scattered and poorly accessible

  4. A NEED FOR … • Overview on the state of the Bothnian Bay and factors affecting it • Identification of main environmental problems (international / national / regional / local) and lack of knowledge • Toolsand guidelines • for harmonized management and monitoring • aiding also in the implementation of WFD

  5. Bothnian Bay Life 2001-2005 Environmental Information Database BAT Information Exchange System Water Quality and Ecosystem Model Bothnian Bay Action Plan INTEGRATED MANAGEMENT SYSTEM FOR THE BOTHNIAN BAY http://www.ymparisto.fi/perameri

  6. ENVIRONMENTAL INFORMATION DATABASE Processed data on • water quality • point loading • material transport Parametres describing • eutrophication • metal loading

  7. WATER QUALITY AND ECOSYSTEM MODEL Free of charge tool for expert use in management purposes in the area Three ”hot spot” modelling areas along the coast Piteå: leakage of sewage – concentration fields in June and September

  8. THE BOTHNIAN BAY ACTION PLAN Analysis of main environmental problems and lack of knowledge Guidelines for integrated status assessment and monitoring Targets and priorities towards sustainable development

  9. THE BOTHNIAN BAY - RBDs • Coastal areas - • 5 RBDs • Finnish side: 3+1 -Swedish side: 1 • Four authorities in charge of WFD implementation & reporting • Cooperation between the authorities

  10. Bothnian Bay is a sensitive, lakelike system with restricted water exchange with southern basins of the Baltic Sea Open sea is not included in WFD / coastal areas shared between five RBD’s • Also overview on the • state of the sea important • in the future: • Harmonizing ! • Cooperation !

  11. It has been calculated that in 2500 years the Bothnian Bay will be a large lake due to land uplift that started after the ice age

  12. Thank you!
