| Description | Complex of open heathland and low open forest. Wind-exposed granite and rhyolite coastal headlands and islands, on skeletal soils. Not a Wetland. (BVG1M: 29a). Vegetation communities in this regional ecosystem include: 7.12.54a: Woodland, low woodland, low forest and shrubland with Corymbia tessellaris, C. intermedia, Lophostemon suaveolens, Eucalyptus platyphylla, Melaleuca viridiflora, Acacia crassicarpa, A. flavescens, A. celsa, A. polystachya, Dillenia alata, Atractocarpus sessilis and Cyclophyllum coprosmoides. Includes a small area of Eucalyptus portuensis low woodland and open forest on Great Palm Island. Steep exposed coastal headlands and hillslopes, on granite and rhyolite. Not a Wetland. (BVG1M: 9c). 7.12.54b: Low heath shrubland and grassland complex of coastal headlands with Melaleuca viridiflora, Allocasuarina littoralis, Casuarina equisetifolia, Lophostemon suaveolens, Acacia holosericea, Acacia polystachya, Lophostemon grandiflorus, Acacia calyculata, Thryptomene oligandra, Pittosporum ferrugineum, Xanthorrhoea johnsonii and Alyxia spicata. Coastal headlands on granite. Not a Wetland. (BVG1M: 29a). 7.12.54c: Themeda triandra tussock grassland. Coastal headlands on granite. Not a Wetland. (BVG1M: 29a). 7.12.54d: Acacia julifera low open forest and shrubland. Coastal headlands. Granite and rhyolite. Not a Wetland. (BVG1M: 28e). 7.12.54e: Casuarina equisetifolia low open forest. Rocky coastal headlands of Orpheus Island. Not a Wetland. (BVG1M: 28a). 7.12.54f: Themeda triandra grassland. Coastal headlands on the Black Trevethan Range. Rhyolite. Not a Wetland.

| Fire management guidelines | SEASON: Do not burn deliberately. f: Early season burns (April-June). Later burns during storm season will reduce shrub invasion. INTENSITY: Do not burn deliberately. f: Low, with occasional moderate. INTERVAL: Do not burn deliberately. f: 2-3 years. INTERVAL_MIN: 2. INTERVAL_MAX: 100. STRATEGY: Maintain appropriate mosaic burning in surrounding country. Do not protect from fire but do not burn deliberately. f: Mosaic burn at a range of frequencies to create mosaic of post-fire responses. ISSUES: This is mainly a self protecting community. Allocasuarina littoralis is killed by fire. f: Absence of fire can lead to a transition to shrubland. Moderate intensity fire will reduce this change and assist with weeds. |
| Comments | 7.12.54: Eucalypt components are distinguished from 7.12.23 by their low wind-sheared nature. (7.12.23 is a medium to tall forest). Distributed patchily along the entire coastal edge of the bioregion. 7.12.54g: Patches of bare rock < 0.2 ha are defined as more open areas of the surrounding ecosystems. |
