| Short description | Corymbia intermedia +/- Eucalyptus acmenoides open forest to low woodland with lower tree layer of Allocasuarina torulosa, Livistona decora on igneous rocks. Coastal hills |
| Structure code | Open Forest |
| Description | Corymbia intermedia and Eucalyptus acmenoides open forest to low woodland, with distinctive lower tree layer of Allocasuarina torulosa and Livistona decora. Ground to shrub stratum frequently with Xanthorrhoea johnsonii. Occurs on coastal ranges formed on Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 27c). |
| Supplementary description | Sandercoe (1990), 22 |
| Protected areas | Cape Upstart NP, Magnetic Island NP, Mount Abbot NP (S), Bowling Green Bay NP |
| Special values | 11.12.15: Potential habitat for NCA listed species: Ozothamnus eriocephalus, Parsonsia larcomensis. |
| 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: Low to moderate. INTERVAL: 6 -10 years. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Maintain fire management of surrounding country so that wildfires will be very limited in extent and do not penetrate Lancewood forests. ISSUES: Maintaining a fire mosaic will ensure protection of fauna habitats (such as dense stands of A. luehmannii) and mitigate against wildfires. Allocasuarina luehmannii (bull oak) can be both killed by fire and regenerate from seed following fire. Bull oak thickening/creation of whipstick communities may be controlled with planned low intensity burns. Drought index will help deliver required guideline. Jewel butterfly is significant in this community, but the jewel butterfly needs thick leaf litter/mature bull oak; so high intensity fire (or fire that removes the litter layer) could be detrimental to survival. Allocasuarina is also an important food source for glossy-black cockatoo. |
| Comments | 11.12.15: Found only on coastal hills and ridgelines above about 350 m. Generally in good condition. |
