The foreshore and dune system
The Mordialloc foreshore is characterised by a range of landforms, varying from the historically significant Beaumaris cliffs and sea ledges with views across the bay to the wide, sandy, safe beach at Mordialloc. These features add variety to the coastline and are attractive to visitors.
While much of the original vegetation has been cleared from the foreshore this environment group has strongly supported the revegetation work being carried out by the local council. Significant indigenous vegetation can be observed while on the foreshore walk included.
Coastal sand dunes are formed when sand deposited on the shore dries out and is blown to the back of the beach. Dune grasses help to hold the sand in position especially during severe storm surges. and so helps to prevent erosion of the foreshore.
The present day coastal dune system was formed during the last 6000 years. Between Mordialloc and Frankston a coastal barrier was formed behind which lay the fresh water Carrum Carrum Swamp.
In 1866, when Rawlinson first surveyed this area, water from these swamps ran either north into Mordialloc Creek or south into Kananook Creek.
