All saltmarsh is significant in Raglan Harbour due to its limited extent – primarily dictated by the harbour geology, but also due to past infilling. Similarly all remaining freshwater wetlands/swamp forest that backs onto estuarine wetland should be actively preserved and enhanced due to its scarcity and habitat value.
Saltmarsh ribbonwood is uncommon in the harbour which is also a reflection of the harbours geology providing little flat land extending inland on which estuarine communities can grade into freshwater communities. The relatively small amounts of habitat available for saltmarsh ribbonwood have also often been modified for farming (either through grazing or infilling).
The two most significant future threats to the harbour’s estuarine vegetation (and water quality) are weeds and stock.
