Short description Saltpan vegetation including grassland, herbland and sedgeland on marine clay plains
Structure category Grassland
Description Saltpan vegetation comprising Sporobolus virginicus grassland and samphire herbland.

Fire management guidelines STRATEGY: Do not burn deliberately. No fire management required. Largely non-flammable vegetation.
Comments Tidally inundated less frequently than mangroves. This ecosystem is under threat from sea level rise along its seaward margin.

1 Estimated extent is from version 11 pre-clearing and 2017 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
