Coastal 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, Sea Rush (Juncus krausii subsp. australiensis), Samphire (Sarcocornia quinqueflora subsp. quinqueflora), Marine Couch (Sporobolus virginicus), Streaked Arrowgrass (Triglochin striata), Knobby Club-rush (Ficinia nodosa), Creeping Brookweed (Samolus repens), Swamp Weed (Selliera radicans), Seablite (Suaeda australis) and Prickly Couch (Zoysia macrantha). Occasionally mangroves are scattered through the saltmarsh. Tall reeds may also occur, as well as salt pans.


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).
