|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |

| Short description | Eucalyptus microtheca +/- Corymbia papuana open woodland on floodplains |
| Structure code | Open Woodland |
| Description | Eucalyptus microtheca open woodland+/- Corymbia papuana. The very sparse sub canopy can sometimes contain scattered Barringtonia acutangula. The very sparse shrub layer contains scattered Cathormion umbellatum Antidesma ghaesembilla and Melaleuca viridiflora. The sparse to mid-dense ground layer can contain Eriachne spp., Melochia corchorifolia and Schizachyrium fragile. Occurs on floodplains. Not a Wetland. (BVG1M: 16c). Vegetation communities in this regional ecosystem include: 3.3.37a: [RE not in use]²: This vegetation community is now mapped as RE 3.3.37. Open woodland of Eucalyptus microtheca +/- Corymbia papuana. The very sparse sub canopy can sometimes contain scattered Barringtonia acutangula. The very sparse shrub layer can contains scattered Cathormion umbellatum Antidesma ghaesembilla and Melaleuca viridiflora. The sparse to mid-dens ground layer can contain Eriachne spp., Melochia corchorifolia and Schizachyrium fragile. Occurs on floodplains. Not a Wetland. (BVG1M: 16c). 3.3.37b: [RE not in use]²: This vegetation community is now mapped as RE 3.3.37. Scattered trees of Corymbia dallachiana (Dallachy's gum) (9-15m tall) dominate the biomass and form a very sparse canopy. Occasional Eucalyptus leptophleba (Molloy red box) trees may be present. Shrubs and low trees are usually absent and the dense, tall ground layer is dominated by grasses. Themeda arguens, Heteropogon triticeus (giant speargrass) and Capillipedium parviflorum (scented top) are the primary grasses. H. contortus (black speargrass), Dichanthium sericeum subsp. sericeum (Queensland blue grass), Sarga plumosum (plume sorghum) and Mnesithea rottboellioides (northern cane grass) dominate small areas. Occurs on flood plains. Not a Wetland. (BVG1M: 32b). |
| Protected areas | Oyala Thumotang NP (CYPAL) |
| Special values | 3.3.37: Northernmost populations of Eucalyptus microtheca. In some areas, Eucalyptus leptophleba (Molloy red box) may replace E. microtheca. |
| 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: 1-3 years. INTERVAL_MIN: 1. INTERVAL_MAX: 3. 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. These communities require particular management attention due to issues of grazing, weed invasion, rapid fuel accumulation, poor access and woody thickening. Fuel can reach maximum accumulation in 2 years. |
| Comments | 3.3.37: Corymbia dallachiana previously known as C. papuana. Where invasion of vine thicket species has occurred this becomes a vegetation community in 3.3.38e. Archer River. These areas are regularly flooded and sometimes large areas are swept clean of ground vegetation. 3.3.37a: In some areas, Eucalyptus leptophleba (Molloy red box) may replace E. microtheca. Archer River. These areas are regularly flooded and sometimes large areas are swept clean of ground vegetation. 3.3.37b: Central Peninsula. |
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.
