As well as being a recognised feature of the sand dunes, marram grass plays a vital role in dune habitats as it helps to reinforce the structural integrity of the dune. The fibrous roots of marram grass bind sand together allowing for more sand to build up and create the dune systems we see at beaches. The binding of the sand ultimately increases the biodiversity of the habitat as it encourages the establishment of other plants in the dune habitat which attracts various insects and animals.
