| Regional ecosystem | 3.3.46 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Extent in reserves | This regional ecosystem is now mapped as 3.3.37. |
| Short description | Eucalyptus microtheca +/- E. chlorophylla low open woodland on Mitchell River alluvia |
| Structure code | Low Open Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.3.37. Scattered Eucalyptus microtheca (coolibah) dominate the very sparse to sparse canopy layer (5-12m tall). E. chlorophylla and Corymbia dallachiana (Dallachy's gum) are sometimes present in the canopy. Grevillea striata (beefwood) is frequently present as a sub-canopy tree (6-8m tall). A conspicuous shrub layer is rarely present. The ground layer is mid-dense and dominated by grasses. Themeda arguens, Brachyachne convergens, Sarga plumosum (plume sorghum), Aristida spp. and Eriachne spp. dominate the ground layer in various localities. Occurs on flat alluvial plains. Not a Wetland. (BVG1M: 16c). |

| Fire management guidelines | SEASON: Early to mid-dry season. INTENSITY: Low to moderate. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Burn under mild conditions. ISSUES: Patch burns implemented early in the season will limit the extent and intensity of wildfires. |
| Comments | 3.3.46: Mitchell River. Cryptostegia grandiflora infestations in some areas. |
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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
