| Structure code | Tall Open Shrubland |
| Description | Mixed tall open shrubland to low open woodland, including combinations of the species Excoecaria parvifolia, Melaleuca acacioides, Grevillea striata, Hakea pedunculata and M. foliolosa. The ground layer is a combination of tussock grasses and sedges, including Eriochloa spp., Xerochloa imberbis, Heterachne spp., Sporobolus virginicus, Fimbristylis spp. and Eleocharis sp. Occurs on coastal alluvial surfaces adjacent to the tidal zone. Saline clay soils. Not a Wetland. (BVG1M: 21b).

| Fire management guidelines | SEASON: March to April, with occasional storm burns if woody weeds are a problem. INTENSITY: Low, occasionally moderate and high intensities. INTERVAL: 3-6 years south of latitudes below Karumba, 1-3 years to the north. INTERVAL_MIN: 1. INTERVAL_MAX: 6. STRATEGY: Do not actively target burning of sedgelands. Commence burning early in dry season to break up continuity of fuel across the landscape. Mosaic burning across the landscape at varying frequency will create patches at varying stages of post-fire response. Burn with good soil moisture to promote regeneration. ISSUES: Retaining grasslands by preventing woody thickening may be an issue in some situations. A long absence of fire or low intensity fire too early in the season may lead to overabundant seedlings and saplings. Invasive and high biomass grasses (e.g., buffel, Para and grader grasses) may increase fire severity to the detriment of these ecosystems. |
