| Short description | Asteromyrtus lysicephala and Thryptomene oligandra open heath on alluvial plains |
| Structure code | Open Heath |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.3.53b. Asteromyrtus lysicephala (back to front bush) dominates the sparse shrub layer (0.5-1.5m tall). Neofabricia myrtifolia (yellow teatree), Alyxia spicata and Lomandra banksii occur at high densities in the shrub layer. Scattered Melaleuca arcana (Cape York paperbark), M. nervosa (woodland paperbark) and Lophostemon suaveolens (swamp mahogany) occur as emergent trees (8-10m tall). Scattered emergent Banksia dentata shrubs (4m tall) are also present. The ground layer is sparse and dominated by Schoenus sparteus and Eriachne pallescens. Occurs on alluvial plains and pediment fans. Not a Wetland. (BVG1M: 29a). |

| Fire management guidelines | SEASON: August-September up to November depending on the season. INTENSITY: Patchy and low or moderate to high. Fires will tend to burn either with high intensity or at low intensity. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Apply a mosaic across the landscape at a range of intervals to create areas of varying post-fire response. Burn 10-20% of the landscape. ISSUES: These ecosystems typically have a longer fire interval than surrounding vegetation, so it is important to manage fire in surrounding country to avoid too frequent fire. Planned burns in and around heath will assist in breaking up the continuity of fuels across the landscape, preventing late season wildfires which have deleterious ecological effects. |
| Comments | 3.3.55: The structure of this regional ecosystem varies greatly depending on micro relief and fire history. In areas of impeded drainage, Melaleuca arcana trees may dominate. Headwaters of the Jack River and the lower Dulhunty River. |
1 Estimated extent is from version 13.1 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.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
