| Short description | Eucalyptus crebra woodland on old sedimentary rocks with varying degrees of metamorphism and folding. Coastal ranges |
| Structure code | Woodland |
| Description | Eucalyptus crebra woodland +/- Corymbia citriodora +/- E. tereticornis +/- C. tessellaris +/- Lophostemon suaveolens with Xanthorrhoea spp. and Macrozamia spp. often present in shrub layer. Eucalyptus moluccana often dominates the tree canopy on lower colluvial slopes. Generally occurs on coastal hills and ranges formed on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Not a Wetland. (BVG1M: 13c). Vegetation communities in this regional ecosystem include: 11.11.4a: Eucalyptus tereticornis dominated woodland. Other tree species listed above may occur as sub or co-dominant species. On undulating hills and low rises of metasediments. Not a Wetland. (BVG1M: 13d). 11.11.4b: Corymbia trachyphloia or Eucalyptus acmenoides, E. crebra woodland +/- Acacia leiocalyx. Occurs on rocky coastal rises and steep hills, on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics and Permian sediments. Not a Wetland. (BVG1M: 13c). 11.11.4c: Eucalyptus moluccana dominated woodland. Other tree species listed above may occur as sub or co-dominant species. Occurs on undulating rises and low hills, on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics and Permian sediments. Not a Wetland. (BVG1M: 13d). 11.11.4d: Lophostemon spp. with shrubs including Acacia spp. Alphitonia excelsa and Xanthorrhoea johnsonii. Occurs on coastal rocky short steep hills on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics and Permian sediments. Not a Wetland. (BVG1M: 28e). |

| Special values | 11.11.4: Potential habitat for NCA listed species: Cycas megacarpa, Cycas ophiolitica, Macrozamia serpentina, Marsdenia brevifolia, Parsonsia larcomensis, Rhaponticum australe, Zieria actites, Zieria verrucosa. |
| Fire management guidelines | SEASON: Late wet to early dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Various. INTERVAL: 6-15 years (shorter intervals north of bioregion: 5 - 10 years). INTERVAL_MIN: 5. INTERVAL_MAX: 15. STRATEGY: Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. All shrubby areas will carry fire after a good season. ISSUES: Management of this fire tolerant vegetation type should be based on maintaining vegetation composition, structural diversity, animal habitats and preventing extensive wildfire. Maintaining a fire mosaic will ensure protection of habitat and mitigate against wildfires. Planned burns have traditionally been carried out in the winter dry season; further research required. |
