| Description | Eucalyptus moluccana or E. microcarpa or E. woollsiana (restricted to south of bioregion) open forest. Allocasuarina luehmannii can be present in understorey. Occurs on Cainozoic to Proterozoic consolidated, fine-grained sediments. Lower slopes. Not a Wetland. (BVG1M: 13d). |

| Protected areas | Homevale NP, Carnarvon NP, Main Range NP, Homevale RR, Morgan Park CP |
| Special values | 11.9.13: Habitat for uncommon mallee eucalypt species including Eucalyptus bakeri and E. viridis in the Inglewood-Warwick area. |
| 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: Restrict to less than 30-60% in any year. Rotate burns in mosaic patches. Maintain fire management of surrounding country so that wildfires will be very limited in extent. Burn under conditions of good soil moisture and when plants are actively growing. 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. |
