| Structure code | Open Forest |
| Description | Casuarina equisetifolia (coast sheoak) +/- Corymbia tessellaris (Moreton Bay ash) open forest +/- groved vine forest shrublands. Beach strand and foredune. Not a Wetland. (BVG1M: 28a). Vegetation communities in this regional ecosystem include: 7.2.7a: Complex of open shrubland to closed shrubland, grassland, low woodland and open forest. Includes pure stands of Casuarina equisetifolia, and Acacia crassicarpa, Syzygium forte subsp. forte, Calophyllum inophyllum and Pandanus spp. woodland to open forest. Beach strand and foredune. Not a Wetland. (BVG1M: 28a). 7.2.7b: Groved shrubland with Corymbia tessellaris, Casuarina equisetifolia and vine forest species including Canarium australianum, Terminalia arenicola, Sersalisia sericea. Alluvial terrace behind coastal boulder ridge, only on the Palm Islands. Not a Wetland. (BVG1M: 28a). 7.2.7c: Areas of open sand. Coastal dunes (excluding the beach). Not a Wetland. (BVG1M: 28d). |

| Special values | 7.2.7b: This regional ecosystem occurs on a very unusual landform. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. 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. 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. |
| Comments | 7.2.7: Extremely vulnerable to weed invasion, and subject to recreational disturbance and encroachment by housing developments. Most examples are invaded by weeds, many quite severely. Common weed species include Sphagneticola trilobata (Singapore Daisy), Cenchrus echinatus, Melinis repens, Tridax procumbens, Megathyrsus maximus (Guinea grass), and Mesosphaerum suaveolens. 7.2.7a: Occurs on the majority of foredunes in the Wet Tropics. 7.2.7b: Palm Islands. |
