| Short description | Corymbia polycarpa +/- C. curtipes woodland on Mitchell River levees |
| Structure code | Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 2.3.72. Corymbia polycarpa (long-fruited bloodwood) dominates the sparse canopy (13-20m tall). C. curtipes (a bloodwood), C. confertiflora (cabbage gum), Canarium australianum (scrub turpentine) and Erythrophleum chlorostachys (Cooktown ironwood) may be present as subdominant canopy trees. The sub-canopy tree layer (4-12m) varies from very sparse to sparse. Terminalia spp., Erythrophleum chlorostachys, Melaleuca nervosa (paperbark), Corymbia polycarpa and Lysiphyllum cunninghamii (bean tree) are the most commonly encountered species. The very sparse to sparse shrub layer (0.5-4m tall) is dominated by a variety of species depending on the location. Aristida spp. (three-awned speargrass), Panicum spp. (panic) Themeda arguens, Heteropogon contortus (black speargrass) and Arundinella setosa (reed grass) are the most frequent species in the sparse to mid-dense ground layer. Occurs on levees. Not a Wetland. (BVG1M: 9e). |

| Fire management guidelines | SEASON: Commence planned burns early in the dry season, after the wet season when dry enough to burn. Use occasional storm burns but generally avoid periods of extremely hot, dry conditions. INTENSITY: Low to moderate with occasional high during storm burns. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Apply a mosaic across the landscape at a range of intervals to create varying stages of post-fire response. Burn 30-60% at the property level. ISSUES: To mitigate against the impact of late dry season fires, commence burning early in the season and continue through the dry to break up continuity of fuels across the landscape. Planned fire applied repeatedly early in the dry season may lead to woody thickening because fires are not of sufficiently high intensity; this may be exacerbated by stock grazing. Manage extent, intensity and frequency of fires judiciously, to avoid habitat tree loss. |

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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
