Mellum formed as an island off the end of the Butjadingen peninsula – which divides the outflows into the Wadden Sea of the Jade and Weser rivers – only at the end of the nineteenth century.[1] It is chiefly composed of dunes and tidal marshes. The influence of sea currents and winds is constantly altering the shape and position of the island, which in 2006 had a total surface area of approximately 750 hectares (1853 acres).

An important breeding and feeding ground for wild birds, Mellum is part of the Lower Saxony Wadden Sea National Park and a nature protection zone.[2] The island's only house is today used during the summer months for wildlife observation and scientific research purposes only.
