The file presents ecological status of shallow inlets along the Swedish and Finnish Baltic Sea coast (excluding the Botninan Bay, the Quark and southern Scania County). The ecological status is based on submerged macrophytes and follows guidelines for biological quality elements in the European Union Water Framework Directive. The method was developed by Joakim Hansen (Stockholm University) during the project NANNUT (European Regional Development Fund, Central Baltic Interreg IVa, Archipelago and Islands). Macrophyte surveys were conducted in late July to early September 2001–2010 using the method of Persson & Johansson (2007). The classified inlets have been surveyed with a minimum of three line transects, which were located to represent most of the inlet area. A number of inlets have been surveyed during several years, other inlets just one year. The method for classification of ecological status is described in Hansen (2012), and full data is stored in the database 'GRUNDA' (2011).
