The island was first recorded in 1597 as '' Norder Ough '' . In 1630 there was a permanent estate on Noorderoog that was inhabited by a beach warden . This dwelling was destroyed in the Burchardi flood of 1634 . Later , another family settled there but their house was washed away in the February flood of 1825 . From then , Norderoog remained uninhabited . It is the only hallig that does not have a terp for dwelling . Since 1909 , the island is owned by '' Verein Jordsand '' , an association that promotes the creation of bird refuges along the German North Sea coast
