Uninhabited, they remain one of the few areas in the Wadden Sea that are unaffected by direct human activity.

Numerical simulations by the University of Kiel have shown the likelihood of a merger between Japsand and Norderoogsand by 2050.

The plant carpet helps to accumulate ever more sand, and so the peak dune of Norderoogsand was recorded with 3.50 metres in 2013.

[2] Together with the Hooger Loch and Rummelloch-West gats, as well the Halligen of Norderoog and Süderoog, the shoals are a popular resort for seals and form one of the main moulting areas of the common eider.

[1] The shoals are part of the core zone of the Schleswig-Holstein Wadden Sea National Park and must not be entered except for the northern areas of Japsand.
