Figure 37-2 illustrates material transport along the west coast of Jutland. In the geopark area the entire coast is subjected to erosion and it is evident that enormous amounts of sediments are transported by waves and currents. Between Ferring and Thyborøn material transport is dominantly to the north and the eroded material is transported through the canal at Thyborøn and into Nissum Bredning where it is deposited as sand banks. These form a huge delta-like structure. South of Ferring transport is towards the south and a large proportion of the material is deposited at Blåvands Huk and on Horns Rev. It is noteworthy that this pattern of material transport is partly controlled by mankind, since the role of Nissum Bredning as an area for sediment deposition depends on the canal at Thyborøn being kept open artificially.
Since the coast is subject to major erosion, the Danish Coastal Authority uses considerable resources for coastal protection initiatives. This used to be in the form of structures like groynes, barriers and revetments, but today the strategy is mainly to replace the eroded sand with new supplies. Sand is either pumped onto the beach or deposited in shallow water. This initiative has reduced coastal erosion to a minimum at the present time.
Overall this locality is a splendid example of a simplification coastline in a glacial landscape. Between the highland areas formed by the glacial deposits at Husby, Bovbjerg and Thy, material transport along the coast has resulted in the construction of impressive natural barriers (Nissum Bredning, lake Ferring Sø, Nissum Fjord). This type of coastline is very different from the North Sea coast further north and south. The stretch of coast in GPWJ has been considerably modified by mankind, but this only serves to emphasize the power of nature in the area.
Parts of the coast have been nominated as a Natura 2000 bird protection and habitat site, and there are also Ramsar areas and nature reserves. Dune heathland (site 33 Husby Klitplantage) is a particularly characteristic type of landscape. The area is part of NGI 76 and NK 80. Several stretches along the coast are protected conservation areas.
