| Short description | Saltpan vegetation including grassland, herbland and sedgeland on marine clay plains |
| Structure code | Tussock Grassland |
| Description | Saltpan vegetation comprising Sporobolus virginicus grassland and samphire herbland. Grasses including Zoysia macrantha subsp. macrantha sometimes present in upper portions of tidal flats. Includes saline or brackish sedgelands. Usually occurs on hypersaline Quaternary estuarine deposits. Marine plains/tidal flats. Intertidal. (BVG1M: 35b). |

| Special values | 12.1.2: Habitat for threatened fauna species including the false water-rat Xeromys myoides in the southern part of the bioregion particularly in areas immediately adjacent to mangroves, 12.1.3. ( Van Dyck and Gynther, 1996, 2003). |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. No fire management required. Largely non-flammable vegetation. |
| Comments | 12.1.2: Tidally inundated less frequently than mangroves. This ecosystem is under threat from sea level rise along its seaward margin. |
