| Structure code | Shrubland |
| Description | Shrubland, sedgeland and heath complex with Thryptomene oligandra and/or Asteromyrtus spp., +/- Melaleuca quinquenervia (swamp paperbark). Sandplains of beach origin. Contains Palustrine. (BVG1M: 29a). Vegetation communities in this regional ecosystem include: 7.2.10a: Thryptomene oligandra low open forest, closed shrubland and heath complex. Longitudinal sand dune systems. Not a Wetland. (BVG1M: 29a). 7.2.10b: Asteromyrtus lysicephala, Asteromyrtus angustifolia, Thryptomene oligandra, Acacia crassicarpa, Jacksonia thesioides, Leucopogon yorkensis, Hibbertia banksii, Cyclophyllum coprosmoides and Aidia racemosa open to closed scrub and heath. Longitudinal sand dune systems. Not a Wetland. (BVG1M: 29a). 7.2.10c: Low open forest, shrubland and sedgeland complex with Melaleuca quinquenervia, Asteromyrtus lysicephala, Deplanchea tetraphylla, Dillenia alata, Gahnia sieberiana, Pandanus sp., Lepironia articulata, Nepenthes mirabilis, Blechnum indicum, Myrmecodia beccarii. Permanently moist areas of deep fibrous peat. Palustrine. (BVG1M: 29a). 7.2.10d: Allocasuarina littoralis woodland to open forest. On aeolian dunes at Yarrabah. Not a Wetland. (BVG1M: 28a). 7.2.10e: Acacia flavescens, Allocasuarina littoralis and Allocasuarina torulosa low shrubby open forest to woodland. Aeolian dunes at Yarrabah. Not a Wetland. (BVG1M: 28a). |

| Special values | 7.2.10: Notable for the plant species occurring at extremes of their range (species which are more typical of the Cape York bioregion). |
| Fire management guidelines | SEASON: Do not burn deliberately. c: Early to mid-dry season. INTENSITY: Do not burn deliberately. c: Low with occasional moderate. INTERVAL: Do not burn deliberately. c: 3-10 years. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Limit fire encroachment from adjacent ecosystems by burning when conditions are favourable. Burn away from edges. c: Burn with anticipated rain as it will increase patchiness. Create burn mosaics using progressive burning. Do not deliberately burn submerged swamps but allow fire to carry into their edge. ISSUES: Most plant species in this ecosystem are fire sensitive. Inappropriate fire may affect sensitive trees (e.g., coastal she-oaks), remove habitat trees, remove structurally complex understorey or promote weed invasion and erosion. c: Avoid peat fires and maintain awareness of high biomass grasses which can increase fire intensity and spread. Avoid burning ant plants. |
