| Structure code | Woodland |
| Description | Eucalyptus chlorophylla (silver-leaved box) woodland to low open woodland +/- Corymbia clarksoniana (Clarkson's bloodwood) +/- Erythrophleum chlorostachys (Cooktown Ironwood). A very sparse subcanopy can contain Melaleuca viridiflora (broad leaved tea tree) and M. nervosa (fibrebark). A very sparse shrub layer often contains juvenile canopy species and a range of Acacia spp. (wattles). The sparse to dense grassy groundlayer is often dominated by Heteropogon spp. (speargrass), Themeda spp. And Sarga plumosum (sorghum). Occurs on alluvial plains. Not a Wetland. (BVG1M: 16c). |

| 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 | 3.3.16: RE 3.3.45 and parts of RE 3.3.36 were amalgamated into this RE. Mainly in the south-east. |
