Coastal Saltmarsh in the NSW North Coast, Sydney Basin and South East Corner Bioregions - profileConservation status in NSW: Endangered Ecological Community DescriptionCoastal Saltmarsh occurs in the intertidal zone on the shores of estuaries and lagoons that are permanently or intermittently open to the sea. It is frequently found as a zone on the landward side of mangrove stands. Characteristic plants include Baumea juncea, Juncus krausii, Sarcocornia quinqueflora, Sporobolus virginicus, Triglochin striata, Isolepis nodosa, Samolus repens, Selliera radicans, Suaeda australis and Zoysia macrantha. Occasionally mangroves are scattered through the saltmarsh. Tall reeds may also occur, as well as salt pans. Location and habitatDistribution This community occurs in the intertidal zone along the NSW coast. Habitat and ecology- Species composition varies with elevation and latitude, with Saltmarsh in southern NSW being generally more species-rich than further north.
- The sediment surface may support a diversity of seaweed species.
- Species restricted to coastal saltmarshes include Distichlis distichophylla (endangered), Halosarcia pergranulata subsp. pergranulata, Wilsonia backhousei (vulnerable) and Wilsonia rotundifolia (endangered).
Regional information This species is found in the following catchment management authority regions. Click on a region name to see more details about the distribution, vegetation types and habitat preference of the species in that region. Threats- In-filling for development, including roads, residential, industrial, recreational, waste disposal and agricultural purposes.
- Modification of tidal flows as a consequence of artificial structures being erected.
- Alteration of salinity and increasing nutrient levels resulting from the discharge of stormwater into saltmarshes.
- Weed invasion, particularly by Juncus acutus.
- Physical damage from human disturbance, domestic and feral animals.
- Dumping of rubbish and pollution from oil or chemical spills from shipping or road accidents; catchment runoff of nutrients and agricultural chemicals.
- Invasion by mangroves.
- Inappropriate fire regimes.
Recovery strategiesPriority actions are the specific, practical things that must be done to recover a threatened species, population or ecological community. The Department of Environment and Conservation has identified 12 priority actions to help recover the Coastal Saltmarsh in the NSW North Coast, Sydney Basin and South East Corner Bioregions in New South Wales. What needs to be done to recover this species?- Protect areas of saltmarsh from runoff that contains high levels of nutrients or pollutants.
- Reduce the amount of sediment reaching the estuary to reduce migration of mangroves.
- Maintain buffer zones of terrestrial vegetation adjacent to saltmarsh to allow for expansion of saltmarsh and to minimise nutrient flow.
- Allow areas of saltmarsh to regenerate naturally where possible.
- Protect from clearing and development through fencing, signage and active management.
- Minimise human disturbance by preventing access from recreational vehicles, including four wheel drives.
- Erect educational signs to provide information to visitors and residents of the importance of coastal saltmarsh.
- Undertake weed control programs.
- Prohibit grazing and burning.
- Restore natural hydrological regime by removing stormwater drains or artificial structures that restrict tidal flows.
- Consult with Department of Primary Industries (formerly NSW Fisheries) to determine an appropriate mangrove management program.
