 The area down to Potters Point supports heath lands on sandstone and heath on dunes, which are characterised by old man banksia ("Banksia serrata"), sheoak ("Allocasuarina distyla") and grass trees ("Xanthorrhoea resinosa").There are also wetlands on sandstone and wetlands in dunes which sustain native grasses ("Gahnia sieberana" and "Scripus littoralis"), lemon scented bottlebrush ("Callistemon citrinus"), and heath banksia ("Banksia robur") which are rare in the Sydney region.As well as pockets of dry eucalyptus forest, there are also several pockets of Kurnell dune forest in the southern reaches of the Park and important patches of littoral rainforest.
