| Short description | Eucalyptus laevopinea tall open forest on Cainozoic igneous rocks. Elevated plateaus |
| Structure code | Tall Open Forest |
| Description | Eucalyptus laevopinea tall open forest to open forest. A diffuse low tree layer is composed of juvenile E. laevopinea and mature Macrozamia moorei trees. Scattered low shrubs such as Allocasuarina torulosa occur, rarely forming a well-defined layer. The ground cover is dense and dominated by the grasses Themeda triandra and Imperata cylindrica. Restricted to the tops of high basalt plateaus within the Consuelo Tableland and the Great Dividing Range. It occurs on moderately deep to deep, slightly acidic, humic massive earths. The surface is a weakly structured, dark brown, humic clay-loam which grades into a reddish-brown, light to medium clay with moderately deep to deep humic massive earth soils. Not a Wetland. (BVG1M: 8a). |

| Protected areas | Carnarvon NP |
| Special values | 11.8.1: Habitat of a disjunct population of Eucalyptus laevopinea which is widespread on the coastal mountain ranges of northern NSW. |
| 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: 4-5 years. INTERVAL_MIN: 4. INTERVAL_MAX: 5. STRATEGY: Burn with good soil moisture. Maintain a fire mosaic using 'trickle' fires. Natural fire breaks will occur through this ecosystem and should be used to break up fires. ISSUES: This RE will burn every 2 years but this is too frequent for some species. Planned burns have traditionally been carried out in the winter dry season; further research required. |
| Comments | 11.8.1: Restricted to high (> 300m) plateaus on the Consuelo Tableland and adjacent parts of the Great Dividing Range. Almost all mapped areas are within Carnarvon National Park. |
1 Estimated extent is from version 13 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
