Which type of grass is extensively used in the binding together of sand dunes?
Sand dune ecology disturbed habitats. In the UK these may include restharrow "Ononis repens", sand spurge "Euphorbia arenaria" and ragwort "Senecio vulgaris" - such plants are termed ruderals. Other very specialised plants are adapted to the accretion of sand, surviving the continual burial of their shoots by sending up very rapid vertical growth. Marram grass, "Ammophila arenaria" specialises in this, and is largely responsible for the formation and stabilisation of many dunes by binding sand grains together. The sand couch-grass "Elytrigia juncea" also performs this function on the seaward edge of the dunes, and is responsible, with some other pioneers like the sea
Cronulla sand dunes into 60 smaller paddocks using Brushwood fencing. The fence posts used to divide these lots can still be found in Towra Point, which is also part of the Kurnell Peninsula. Holt attempted grazing, first with sheep which had to be destroyed when they became infected with footrot, and then with cattle. The land on his estate was not suited for intensive grazing, so after most of the trees were felled, herds of cattle then removed the stabilizing grass cover and exposed the sand dunes underneath. Large expanses of sand had been exposed along the coastline. The dune system that covers
