                                     Rabbits may look
                                     cute, but they have
                                       been known to
                                    seriously undermine
                                    the dunes with their
                                      intricate network
                                         of burrows.

                                      Origins
                                      Dunes are created by a process which can be
                                      seen time and time again during a stormy day
                                      on the country’s long, flat beaches. The sand

                                      begins to form. Plants involved in forming
                                      dunes are called pioneer plants. They must be
                                      able to tolerate being buried by the sand and
                                      also be able to grow back through the sand.
                                      Sand couch grass (Elymus farctus) is renowned
                                      for being one such plant. After the initial dune
                                      formation, marram grass often begins to
                                      stabilize the new dune with its enormous
                                      root system. Dunes along the coast of the
                                      Netherlands can become as high as 10 m
                                      (33 ft). The dunes here – new dunes – were
                                      formed after 1200. When the sea breaks
                                      through dunes which have collapsed or have
                                      been cut through, it creates a sea inlet, or
                                      channel, around which an entire vegetation
                                      system develops, attracting all types of birds.
