Spartina anglica colonisation and physical effects in the Tamar Estuary, Tasmania 1971-91

The extent, form and condition of Spartina anglica in the Tamar Estuary changed between the summer of 1971/72 and 1991,probably due to differences in maturity and substrate. This exotic saltmarsh grass stabilised and raised the intertidal mudflats and constrained channel movements, but it has also reduced recreational facilities and its is largely uncontrollable.
