| Structure code | Woodland |
| Description | Eucalyptus chlorophylla low open woodland to woodland, occasionally with Erythrophleum chlorostachys, Terminalia platyptera, Lysiphyllum cunninghamii and Melaleuca spp. A sparse shrub layer may occur, commonly dominated by Carissa lanceolata. The ground layer is tussock grasses, including Aristida spp., Heteropogon spp., Chrysopogon fallax and Sehima nervosum. Occurs on Tertiary residual sand sheets overlying Cretaceous mudstones and siltstones. Yellow to brown loams and texture contrast soils. Not a Wetland. (BVG1M: 18c). Vegetation communities in this regional ecosystem include: 2.5.37a: Eucalyptus chlorophylla woodland, occasionally with Erythrophleum chlorostachys, Lysiphyllum cunninghamii and Terminalia platyptera. A sparse shrub layer may occur, including canopy species, Carissa lanceolata and Dolichandrone heterophylla. The ground layer is tussock grasses, including Aristida spp., Heteropogon spp. and Chrysopogon fallax. Occurs on Tertiary residual sand sheets overlying Cretaceous mudstones in the north-east of the bioregion. Yellow to brown loams and texture contrast soils. Not a Wetland. (BVG1M: 18c). 2.5.37b: Eucalyptus chlorophylla low open woodland to woodland, occasionally with Terminalia platyptera, Melaleuca citrolens and M. viridiflora. A sparse shrub layer commonly occurs, including Carissa lanceolata, Flueggea virosa and Grewia savannicola. The ground layer is tussock grasses, including Chrysopogon fallax, Aristida spp. And Sehima nervosum. Occurs on Tertiary outwash plains overlying Cretaceous siltstones in the west of the bioregion. Yellow to brown clay loams and texture contrast soils. Not a Wetland. (BVG1M: 18c). 2.5.37x1: Mixed low woodland, including combinations of the species Eucalyptus sp. (box), Melaleuca stenostachya, Terminalia platyptera and Lysiphyllum cunninghamii. Occasional canopy species include Erythrophleum chlorostachys and Corymbia polycarpa. A variable lower tree or shrub commonly occurs, including canopy species, Carissa lanceolata and Gardenia vilhelmii. The ground layer is tussock grasses, including Aristida spp. and Sarga plumosum. Occurs on old high-level alluvial deposits and sandy residuals in the north-east of the bioregion. Orange to brown sandy loams. Not a Wetland. (BVG1M: 18c). |
| Fire management guidelines | SEASON: Commence early in dry season as soon as ground fuels can carry fire with fire extinguishing early evening. Continue to mid-dry season. INTENSITY: Low to moderate with occasional high intensity. INTERVAL: 1-5 years, but do not burn the same patches annually. Landscape mosaic should consist of patches with different times since burning. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Break up continuity of fuel across the landscape so that impact of late-season wildfire is minimised. Wildfire due to dry storms late in the dry season or in the early wet are natural occurrences, but they can burn over a wide area of the landscape with unwanted intensity and frequency. Use broad scale mosaic burning. ISSUES: Overabundant seedlings and saplings can lead to woody thickening if unchecked by fire. A long absence of fire or low intensity fire too early in the season may lead to overabundant seedlings and saplings. If ground fuels are sparse spell pastures prior to planned burns. Weeds such as buffel grass and rubbervine may be an issue for some tussock grass communities because weeds increase fuel loads leading to high intensity fires. |
