Dune erosion by human activities
Protected dunes at Port Noarlunga
Coastal dunes are threatened by inappropriate development, which locks up the sand and prevents it
from being available for the natural cycle of beach erosion and rebuilding.
Dunes also face threats from inappropriate recreational activities, introduced weeds
and garden escapes.
