THe Clarence Plains Saltmarsh is an Important Urban Wetland

What is a Saltmarsh ?

Salt marshes form when mudflats are raised to the level of the average high tide. The accumulation of mud is most common in estuaries where the river brings fine-grained sediment to slack water but where wave action cannot rework the settled mud. Grasses tolerant of salt water then slowly take hold and spread, stabilizing the land through the growth of root systems and trapping more sediment.
