Narrabeen Lagoon, NSW

Historical dredging activities has resulted in disturbances to the majority of foreshores of the Narrabeen Lagoon. Occasional mangrove establishment since artificially opening the Lagoon to the sea in 1975, however shoreline reed beds have proved the most effective for stabilising the foreshore. The ready proliferation of reed beds is possible due to the low wave, modest water level change and small current environment of the lagoon.
