Abstract: | A man-made coastal area (8 km long, 300 m wide), constructed from seed-free, marine sand was investigated from 1978 to 1983 as regards relief, soil properties, and establishment of vegetation. The following developments were apparent: - 1.
The outer shore zone changed from a Cakile -dominated vegetation to a sparse and less diverse vegetation. - 2.
The inner shore zone maintained spontaneous Ammophila as dominant and developed into a mobile dune with changing species. - 3.
The outer dune slope with planted Ammophila developed into a mobile dune dominated by vigorous Ammophila. - 4.
The dune zone with planted Ammophila: The outer part developed towards a somewhat fixed dune with increasing diversity. The inner part developed into a diverse and more fixed dune community with mainly Festuca rubra. - 5.
The inner dune slope developed into a vegetation comprising few species. - 1.
The grassland zone, initially sown with Festuca rubra and Lolium perenne , changed into a grass-herb-vegetation dominated by Festuca rubra , with a slowly increasing number of immigrating species, changing from annuals to perennials, in particular species of Fabaceae and Hippophaë.
