| Description | [RE not in use]²: This regional ecosystem is now mapped as 2.2.3, 2.2.4, 2.2.5, 2.2.6 and 2.2.7. Vegetation variable throughout subregion, but includes grasslands, herb fields, woodlands and semi-deciduous and evergreen scrubs. Sedge lands and Melaleuca spp. in swales. Occurs on secondary dunes and swales; unconsolidated sands or stratified shells and mud, and clay soils in swales. Contains Palustrine. (BVG1M: 28a). Vegetation communities in this regional ecosystem include: 2.2.2a: [RE not in use]²: This vegetation community is now mapped as 2.2.7. Corymbia bella low open woodland to woodland, commonly with C. polycarpa, C. confertiflora, Grevillea striata and Pandanus sp. Eucalyptus pruinosa subsp. pruinosa, Hakea arborescens, Atalaya hemiglauca, Acacia spp. and Terminalia spp. occasionally occur in the canopy. A variable shrub layer commonly occurs, including Planchonia careya, Drypetes deplanchei and Diospyros humilis. The ground layer is tussock grasses, commonly Chrysopogon elongatus and Heteropogon contortus. Occurs on Quaternary coastal beach ridges and dunes. Not a Wetland. (BVG1M: 28a). 2.2.2x2: [RE not in use]²: This regional ecosystem is now mapped as 2.2.3. Semi-deciduous microphyll vine thicket, including combinations of the species Diospyros humilis, Drypetes deplanchei, Strychnos lucida, Exocarpos latifolius, Ficus opposita, Acacia crassicarpa, Syzygium suborbiculare, Parinari nonda and Neofabricia myrtifolia. The ground layer is tussock grasses, commonly Perotis rara. The canopy may be discontinuous, with small areas of bare sand and Perotis rara tussock grassland. Occurs on Quaternary coastal beach ridges and dunes. Not a Wetland. (BVG1M: 3a). 2.2.2x3: [RE not in use]²: This regional ecosystem is now mapped as 2.2.4. Mixed tussock grassland, including combinations of the species Chrysopogon elongatus, Eriachne spp., Aristida spp., Oryza sp. and Ophiuros sp. Occurs on Quaternary coastal beach ridges and dunes. Quartzose to shelly sand. Not a Wetland. (BVG1M: 28a). 2.2.2x4: [RE not in use]²: This regional ecosystem is now mapped as 2.2.5. Melaleuca dealbata woodland to open forest, occasionally with Acacia spp. Mixed lower trees and shrubs may occur, including Acacia spp. And Pandanus spp. The ground layer is sparse, including tussock grasses and sedges. Occurs in swales associated with Quaternary coastal dunes and beach ridges. Quartzose to shelly sand. Contains Palustrine. (BVG1M: 22b). 2.2.2x5: [RE not in use]²: This regional ecosystem is now mapped as 2.2.6. Mixed sedgeland (predominantly) or grassland, commonly Cyperaceae species. Occurs in swamps (closed depressions) in the swales of Quaternary coastal beach ridges and dunes. Quartzose sands. Palustrine. (BVG1M: 34c). |

| Special values | 2.2.2: Potential habitat for NCA listed species: Paspalum multinodum. 2.2.2x2: Supports locally uncommon plant species. 2.2.2x5: Seasonally important habitat for water birds feeding and breeding. |
| Comments | 2.2.2: Threatening processes include high total grazing pressure leading to wind erosion, invasion of scrubs by *Cryptostegia grandiflora (rubber vine) and inappropriate fire regimes. 2.2.2a: Threatening processes include high total grazing pressure leading to wind erosion, and invasion by *Cryptostegia grandiflora (rubber vine) and other weeds such as Mesosphaerum suaveolens. 2.2.2x2: Threatening processes include high total grazing pressure leading to wind erosion, invasion of scrubs by *Cryptostegia grandiflora (rubber vine) and inappropriate fire regime particularily in adjacent vegetation communities. 2.2.2x3: Threatening processes include high total grazing pressure leading to wind erosion and invasion of grassland by *Cryptostegia grandiflora (rubber vine). |
1 Estimated extent is from version 13 pre-clearing and 2021 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.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
