About Embryonic shifting sand dunes Danube Delta
Embryonic shifting sand dunes appear as an effect of the winds and of the powerful storms which occur in the coastal area. These dunes become a steady habitat after the evaporation of the water which covers the sandbanks.
Each year, they change their shape and position, depending on the winds or storms which take action in the dunes area. Their specific vegetation transforms, in time, the embryonic shifting sand dunes into fixed dunes.
The embryonic shifting sand dunes provide the perfect habitat for endangered species, such as the Sea Holly or the Petunia littoralis (sand petunia).
