North Frisian Islands The North Frisian Islands (, ; ''Öömrang'' and ''Fering'' ; ''Söl'ring'' ; ) are the Frisian Islands off the coast of North Frisia. The term covers both the North Frisian Islands in the narrow sense (in Schleswig-Holstein, Germany) and the Dan ...

peninsula. During the Middle Ages, Frisian settlers arrived at Amrum and engaged in salt making and seafaring. A part of the modern population still speaks Öömrang, a dialect of the North Frisian language, and Frisian traditions are kept alive. With the island hosting many endangered species of plants and animals, its soil being largely unproductive for agriculture and as a popular seaside resort in general, Amrum's population today almost exclusively lives from the tourism industry.


Geography

Amrum's area measures 20.4 km2, making it the tenth-largest island of Germany (excluding Usedom which is partly Polish territory). Including the large Kniepsand beach on the western shore to the surface area results in a total area of c. 30 km2. Amrum's surface area has however been subject to constant change due to land loss and gain caused by the sea. During the 19th century, a 20th part of the area recorded in the beginning of the century had been lost, but in 1913, a net gain was again recorded at the Kniepsand. Amrum is one of three isles with a geestland core in Nordfriesland. This sandy core is made up of glacial deposits from the Saalian

. To the east, it borders to the Wadden Sea mudflats of the North Sea. The east side is also where the island's historic hamlets are situated: Norddorf, Nebel, Süddorf and Steenodde. On the geestland core, one can find extended areas of heath and woodland which form a strip that runs along a north-south line on the axis. West of this woodland strip, a region of is covered with

s that run all along the island for about 12 km. The maximal width of this area amounts to more than a kilometre. Amrum's tallest dune near Norddorf is called ''a Siatler'' (the settling dune); it reaches 32 m in height. Northward, the dune area extends into a small peninsula called ''Odde''. In the south of Amrum, the newest settlement, Wittdün, is located. West of the dunes, the entire shore of Amrum is made up of the ''Kniepsand'' beach; it counts among northern

Notable sights there include the church of St. Clement with its "talking gravestones", the ''Öömrang Hüs'' - a museum of local history, a wind mill and the Cemetery of the Homeless. Süddorf, today a district of Nebel, is the island's oldest hamlet. The Amrum Lighthouse is located there. Steenodde, also a neighbourhood of Nebel, had long been Amrum's only port until Wittdün, founded 1890, had taken over as the island's major ferry terminal. Of the three municipalities, Wittdün is most clearly influenced by tourism.

until he was allowed to return to his native island in 1736. During the late 19th century, tourism became a rapidly emerging business on Amrum and effectively changed the island's economy. During the Middle Ages, Amrum, as well as all of North Frisia proper, belonged to the so-called '' Uthlande'', the Outer Lands, which only successively became parts of the Danish realm or the Duchy of Schleswig. After the conflicts between the Danish kings and the counts of Schauenburg about the rule over Schleswig, Amrum and western Föhr became an

. For a brief period after that war, Amrum was ruled together by Prussia and Austria, yet in 1867 the island came under Prussian rule and was made a part of the province of Schleswig-Holstein. At first, Amrum formed a municipality within the district of Tondern. In 1920, the Schleswig Plebiscites resulted in a clear majority vote for Amrum staying with Germany, while Tondern fell back to Denmark. Until 1972, Amrum belonged to the ''Südtondern'' district which then merged into the newly created district of Nordfriesland. During the 19th century, Amrum still had a considerably lower population than today. Church records from 1821 to 1833 show an average population of 587, a census in 1860 noted 642 inhabitants, and in 1871, the population had dropped to 571. Among other factors, the decrease owed to the fact that large parts of Amrum's population had emigrated — mainly to the United States. Today, more people with ancestors from Amrum live in the United States than there are on Amrum proper, and the connections between Amrum and the U.S. are still being cultivated. Eventually, tourism began only to flourish on the island when a seaside resort was established in Wittdün in 1890, which also led to a rapid increase in population. On 29 October 1998, the cargo ship ''Pallas'' ran aground off Amrum, causing a severe

Language and culture

The main language on Amrum is German. The North Frisian language in the Öömrang dialect is spoken by roughly a third of the population. Those 800 Amrumers are all multilingual. Due to the isolated location of the islands, the North Frisian dialects developed so differently, that ''Öömrang'' can be understood by people from Föhr, yet is hardly recognisable for those from Sylt or mainland Nordfriesland.

Economy

Amrum's main branch of economy is tourism. In 2007 the island could provide 12,000 beds. In 2008 approximately 135,000 tourists and 1.3 million lodgings were registered. Agriculture is also being practised on Amrum and the port hosts a single fisherman.

Transport

The island is connected by ferry services to neighbouring Föhr and to the mainland at the harbour of Dagebüll. During the summer season, a fast passenger boat offers services between the ports of Hörnum on Sylt, the Hallig Hooge and the harbour of Strucklahnungshörn on Nordstrand. Amrum's terminal is located at Wittdün, the ferries are operated by ''Wyker Dampfschiffs-Reederei GmbH (W.D.R.)''. Most tourists will reach Amrum via Dagebüll. From there, the ferry journey takes 90 minutes on a straight route, but the more usual route via a stop at Wyk auf Föhr takes 120 minutes. The ferry service to the

and the mainland terminal of Schlüttsiel was terminated in 2019 because the port of Schlüttsiel has become too silted up for extended traffic. On the island, the bicycle is the main means of transport next to cars; compared to other areas of Germany, Amrum provides an excellent network of bicycle routes. Numerous bicycle rental services exist for tourists. A bus service connects Norddorf, Nebel and Wittdün on an hourly schedule (every 30 minutes during the summer season). Like the ferries, the bus service is operated by W.D.R.. A less common form of transport is mudflat hiking between Amrum and Föhr. From 1893 to 1939, a railway service was operated on Amrum.

Flora

Amrum's vegetation is determined by the sea and by the different types of landscapes on the island, most of which are low in

Also some stunted pines, bent by the sea wind, and '' Salix repens'', the creeping willow can be found there. Until the 1970s, the rare sea holly could still be seen in the dunes. East of there are heaths and conifer or mixed forests. In some dune slacks, peat bogs can be found which occasionally host the carnivorous plant common sundew. The once abundant marsh gentian vanished during the 1990s. The Amrum forest was mainly planted in 1948 on an area of heath. Until then only a few forested regions could be found around the decoy ponds. With 180

Its grassland grows plants such as Harebell ('' Campanula rotundifolia''), Sea Thrift ('' Armeria maritima'') and Carthusian Pink ('' Dianthus carthusianorum'') and several species of hawkweed. In the small marshlands, some sedges and the ragged robin may be seen. Here is the most nutritious soil on Amrum. Even the soil of Amrum's gardens is so low in nutrients that only a few sorts of plants, e.g.

A few years ago a pregnant vixen was set free on Amrum. She and her offspring caused severe damage to the island's fauna, but since then they have been hunted down.

s have their habitats. Occasionally in December and January, young grey seals are washed ashore on Amrum's beaches due to storm surges and are thereafter nursed by the adults. In January 2010 the seal shelter station at Friedrichskoog announced that more and more female grey seals were "moving away from less favourable birth sites near Amrum and Sylt to Heligoland." Birdlife is particularly plentiful. Amrum counts among the most important hatching areas for

Since the dunes of Amrum are a protected nature reserve, they are the only dunes along the west coast of Schleswig-Holstein where seagulls and ducks breed. In other dune areas of the North Sea coast these birds are usually scared off by tourists. Additionally vast flocks of migratory birds will rest on Amrum during the season, e.g. red knot, brent goose or sanderling, all of whom are able to find sufficient food along the coasts of Amrum.
