Vegetation zones in the Lammermoor Native Gardens: section 7
Beach Foredunes
 
This habitat presents plants with a hostile environment lacking virtually every requirement we would expect to be necessary for their establishment and survival; there is no soil only sand which provides no nourishment, negligible water retention and very poor holding for roots, the plants are also exposed to almost constant, often very strong, salt laden wind.
The beach foredune at Lammermoor has three distinct zones: there is the beach itself then a narrow shelf of sand above the high tide line (called a berm) and then the primary dune.
 
   
 
   
The berm, in the foreground in the photo above, is built up from windblown beach sand accumulating around seaweed, driftwood and other debris left along the high tide line. Plants such as Beach Spinifex and Goats-foot Convolvulus then begin to colonise the growing berm, more sand accumulates around them and the process continues until a stable platform has been established. If the berm continues to grow to seaward sufficient sand will eventually build up to form a low dune on the landward side.
In time this growing dune develops into a foredune and is colonized by Coastal She-oaks that provide protection for plants with a ground hugging habit such as pigface, you can see this on the left in the photo above.  Fore dunes act as barriers against the action of waves, tides and salt wind and are a source of sand for the beach during periods of erosion, they also protect hind dune habitats and promote  more complex and diverse plant communities in these zones.
