Description Predominantly unvegetated but includes areas of Tecticornia spp. and tussock grasses on slightly higher areas. Occurs on saline clay plains; periodically inundated. Solonchaks. Intertidal. (BVG1M: 35b).

Vegetation communities in this regional ecosystem include:
2.1.4x1: Sporobolus virginicus tussock grassland to closed tussock grassland, commonly with Tecticornia spp. and Xerochloa imberbis. Occasional species include Eleocharis sp. and Dichanthium sericeum subsp. polystachyum. Occurs on saline clay plains; periodically inundated. Solonchaks. Intertidal. (BVG1M: 35b).

Protected areas Mutton Hole Wetlands CP, Finucane Island NP
Special values 2.1.4: Most extensive marine plains in Australia. Significant wader habitat. Venturi wetlands. 2.1.4x1: Most extensive marine plains in Australia. Significant wader habitat.
Fire management guidelines INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately, but not necessary to protect from fire. Protection depends on broad-scale management of surrounding country with small fires in surrounding areas used to break up country and limit extent of fire risk. It will occasionally burn in association with fires in surrounding country. ISSUES: Grasses are fire-tolerant, but they are interspersed with samphire that cannot tolerate frequent fire. Ensure that any fire penetrating these communities occur when soils are moist. Fire can be used to control rubber vine in these communities.
Comments 2.1.4x1: Previously part of 2.1.4 or 2.3.1.
