Most motor vehicles are prohibited on the island, with only the fire department, the German Red Cross and doctors allowed to use them.

It was reported by the Reuters news agency, on 24 September 2014, that an unmanned "parcelcopter" will commence delivery of urgent drugs and supplies to the island by DHL.

Around the year 1770 people started to close the 2 km wide burst at the southern side by a dune dike.
