Wind-blown    of  sand  from  dunes  may  carry  far  inland,  covering  fields  and  diverting  streams.  More  seriously,  drifting  sands  can  bury  whole  buildings  and  transform    land  into  desert.  However,  dunes  can  be  made  more  stable  by  the  artificial    of  marram  grass,  a  plant  so  robust  that  it  can  find    even  in  sand.  The  grass  spreads  over  the    of  the  dune,  protecting  it  against  wind,  while  its  roots  bind  the  sand  together.
