| Structure code | Woodland |
| Description | Eucalyptus chlorophylla (shiny-leaved box) dominates the sparse canopy. Erythrophleum chlorostachys (Cooktown ironwood) and Corymbia clarksoniana (Clarkson's bloodwood) often occur as part of the canopy. A very sparse sub-canopy layer is sometimes present. Occasional shrubs of Flueggea virosa subsp. melanthesoides (white currant), E. chlorostachys and Grewia savannicola (dog's balls) form a diffuse layer. The ground layer is sparse to dense and dominated by a variety of graminoids. Themeda triandra (kangaroo grass), T. arguens, Sarga plumosum (plume sorghum), Heteropogon contortus (black speargrass) and H. triticeus (giant speargrass) are frequent dominant grasses. Occurs on undulating plains. Not a Wetland. (BVG1M: 18c). Vegetation communities in this regional ecosystem include: 3.5.24a: [RE not in use]²: This vegetation community is now mapped as 3.5.40. Eucalyptus chlorophylla (shiny-leaved box) dominates the very sparse to sparse canopy. 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. A shrub layer is rarely formed but scattered Dolichandrone alternifolia (lemonwood), Grewia savannicola (dog's balls) and Melaleuca viridiflora shrubs 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 undulating plains. Not a Wetland. (BVG1M: 18c). 3.5.24b: [RE not in use]²: This vegetation community is now mapped as 3.5.24. Eucalyptus chlorophylla (shiny-leaved box) dominates the sparse canopy. Erythrophleum chlorostachys (Cooktown ironwood) and Corymbia clarksoniana (Clarkson's bloodwood) often occur as part of the canopy. A very sparse sub-canopy layer is sometimes present. Occasional shrubs of Flueggea virosa subsp. melanthesoides (white currant), E. chlorostachys and Grewia savannicola (dog's balls) form a diffuse layer. The ground layer is sparse to dense and dominated by a variety of graminoids. Themeda triandra (kangaroo grass), T. arguens, Sarga plumosum (plume sorghum), Heteropogon contortus (black speargrass) and H. triticeus (giant speargrass) are frequent dominant grasses. Occurs on undulating plains and colluvial fans. Not a Wetland. (BVG1M: 18c). |

| Fire management guidelines | SEASON: Dry season. Avoid extremely dry conditions. INTENSITY: Various. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Begin burning early in the fire season, followed by progressive patch fires burnt through the year. ISSUES: Management of this inherently stable, and fire tolerant vegetation type should be based on maintaining animal habitats and preventing extensive wildfire. Maintaining a fire mosaic will ensure protection of animal habitats and mitigate against wildfires. |
| Comments | 3.5.24: In the south 3.5.26 can occur within narrow valleys. Occurs in the south-east of the bioregion on the Laura Basin and south of Cooktown. 3.5.24a: Central bioregion. 3.5.24b: Mainly in the south-east of the bioregion. |
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.
