| Description | [RE not in use]²: This regional ecosystem is now mapped as (part) 3.3.16 and (part) 3.3.24. Eucalyptus chlorophylla (shiny-leaved box) dominates the very sparse to sparse canopy (8-25m tall). Other Eucalyptus spp. are occasionally present in the canopy. Scattered Hakea persiehana (bootlace oak), Melaleuca viridiflora (broad-leaved teatree) and Erythrophleum chlorostachys (Cooktown ironwood) are sometimes present as sub-canopy trees (4-12m tall). A shrub layer is rarely formed but scattered Dolichandrone alternifolia (lemonwood), Grewia savannicola (dog's balls) and M. viridiflora shrubs 0.5-2m tall may be present. The ground layer is sparse to dense and dominated by the grasses Heteropogon contortus (black speargrass), Sarga plumosum (plume sorghum), Themeda arguens, T. triandra (kangaroo grass) and Dichanthium sericeum subsp. sericeum (Queensland bluegrass). Occurs on alluvial plains. Not a Wetland. (BVG1M: 16c). Vegetation communities in this regional ecosystem include: 3.3.36a: [RE not in use]²: This vegetation community is now mapped as 3.3.16.

Occurs on alluvial plains. Not a Wetland. (BVG1M: 16c). 3.3.36b: [RE not in use]²: This vegetation community is now mapped as 3.3.24. Eucalyptus leptophleba (Molloy red box) dominates the very sparse to sparse canopy (8-25m tall) forming open woodlands or woodlands. Corymbia dallachiana (Dallachy's gum) is a frequent codominant tree in the open woodlands while C. clarksoniana (Clarkson's bloodwood) is often present in both structural formations. Other tree species are occasionally present in the woodlands. A very sparse sub-canopy tree layer (4-10m tall) is occasionally present in the open woodlands but more frequently in the woodlands. A very sparse shrub layer (0.5-2m tall) is sometimes present in which Grewia savannicola (dog's balls) and Planchonia careya (cocky apple) are the most commonly encountered species. The ground layer is mid-dense to dense and dominated by a variety of grasses including Heteropogon triticeus (giant speargrass), H. contortus (black speargrass), Sarga plumosum (plume sorghum) and Capillipedium parviflorum (scented top). Occurs on alluvial plains. Not a Wetland. (BVG1M: 9b). |
| Special values | 3.3.36: Potential habitat for NCA listed species: Astonia australiensis, Dendrobium johannis. |
| 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. b: Early to mid-dry season. INTENSITY: Low to moderate with occasional high during storm burns. b: Low to moderate. 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. b: Burn less than 30% in any year. Burn under mild conditions. 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. b: Patch burns implemented early in the season will limit the extent and intensity of wildfires. |

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.
