In order to avoid the risk of pollution and damage to this exceptional, highly dynamic tidal
ecosystem of world importance, mariners should exercise extreme care when navigating in the
area bounded by a line connecting the following geographical positions which is designated as a
Particularly Sensitive Sea Area and in the adjacent area:
The PSSA Wadden Sea is bordered:
Seawards: by an offshore line defined by a set of geographical co-ordinates (see co-ordinates
listed under c.),
Landwards: by the main dikes, or where the main dikes are absent, by the spring-high-tidewater
line, and in the rivers, by the brackish-water limit.
The inhabited islands are excluded from the PSSA. These islands are in:
Denmark: Rømø, Mandø, Fanø
Germany:
Schleswig-Holstein : Pellworm, Nordstrandischmoor, Hooge, Gröde, Langeneß-Oland,
Föhr, Amrum, Sylt, Norderoog, Habel, Süderoog
