(1) The total number of site polygons is lower than the sum of sites at regional/subregional level, because some sites span across different regions or subregions.
NM = nautical miles
The methodology and the procedure used for selecting the marine Natura 2000 sites from the 2017 tabular and spatial data are those illustrated in the EEA report 'Spatial analysis of marine protected area networks in Europe's seas' (2015).
Natura 2000 sites located outside the 200 NM in the North East Atlantic Ocean are not considered.
The table was produced by European Topic Centre on Inland, Coastal and Marine Waters, ETC/ICM.
