Threats to mangroves and saltmarshes
Healthy mangroves and samphire of the upper intertidal zone, Port Gawler Beach.
The extensive areas of samphire and mangroves along the northern shores of the Gulf are
being more widely recognised for their biodiversity and as important nurseries
for commercially valuable fish species, and they are now less likely to be threatened
by inappropriate development.
In the past such areas were regarded as wasteland, fit only for filling and reclamation,
or to be dredged for marina development; this attitude persists in some quarters.
Trail bike riding is a problem in the Port Gawler Conservation Park, but has been reduced
at Mutton Cove on the Lefevre Peninsula by fencing and placement of very large
concrete blocks at access points.
Rusting remains of a car at Port Gawler Beach, a popular dumping ground for stolen vehicles.
