| Short description | Eucalyptus crebra and/or E. drepanophylla and/or E. exserta and/or Corymbia clarksoniana and/or C. xanthope and/or Lophostemon confertus low woodland on metamorphics on islands and headlands |
| Structure code | Low Woodland |
| Description | Eucalyptus crebra and/or E. drepanophylla and/or E. exserta and/or Corymbia clarksoniana and/or C. xanthope and/or Lophostemon confertus open forest to tall shrubland (2.5-15m tall). Other occasional to common associated canopy species may include Allocasuarina littoralis, C. trachyphloia and C. dallachiana. There is sometimes a secondary tree layer of species such as Allocasuarina littoralis, Lophostemon confertus and Acacia julifera. Vine scrub pioneering species may sometimes be prominent. A shrub layer of Xanthorrhoea latifolia subsp. latifolia is often present, with occasional Dodonaea lanceolata var. subsessilifolia, Styphelia imbricata and Lophostemon confertus. The ground layer very sparse to mid-dense and may include Gahnia aspera, Themeda triandra, Xanthorrhoea latifolia subsp. latifolia, Aristida spuria, Scleria mackaviensis, Brunoniella australis, Eriachne pallescens, Lomandra multiflora and Entolasia stricta. Occurs on slopes, ridges and crests on undulating rises to rolling low hills of lowlands and foothills of islands and headlands, on metamorphic rocks. Not a Wetland. (BVG1M: 9c). |

| Special values | 8.11.12: Potential habitat for NCA listed species: Xylosma ovata. |
| Fire management guidelines | SEASON: Late wet to early dry season, with occasional storm burns (Nov-Dec). Winter burns may be acceptable if conditions have not been appropriate for burning until winter. INTENSITY: Low to high but mainly low. INTERVAL: 7-12 years. INTERVAL_MIN: 7. INTERVAL_MAX: 12. STRATEGY: Apply mosaic burns across the landscape at a range of intervals. At a fine scale attempt to create a spatial mosaic with multiple burn patches 20 ha or less; aim for a 30-50% burnt area. At the bioregion scale do not burn more than 20% within the same year. ISSUES: Lack of fire promotes overabundant pioneer rainforest species. Too frequent fire or inappropriately timed fire promotes weeds, including high-biomass grasses that lead to inappropriate fires. At least 7 years between burns is required to permit obligate seeding shrubs to reproduce. |
