Cliffs of City of Marion, SA

Parts of this cliff dominated section of coastline may be at risk of erosion due to both wave action at the base of cliffs and stormwater erosion on the tops of cliffs. To prevent erosion on the cliff top, natural vegetation is encouraged through restriction of pedestrian and vehicle access as well as carefully managed weed control. Some active revegetation is undertaken to restore and maintain the sensitive biodiversity of the area. The area is monitored through annual bushland condition monitoring and aerial terrain captures that form part of the ongoing coastal monitoring program funded equally between state and local government. The program appears to be successful in preventing erosion so far and has provided confidence in understanding risk levels and the suitability of soft nature-based approaches.
