Estimated extent1 Pre-clearing 39000 ha; Remnant 2021 39000 ha
Short description Eucalyptus coolabah open woodland +/- Duma florulenta shrubland on braided channel systems
Structure code Open Woodland
Description Eucalyptus coolabah predominates forming a well-defined but discontinuous canopy with sparsely scattered trees such as Acacia cambagei and Lysiphyllum gilvum and shrubs such as Acacia salicina, Acacia stenophylla and Eremophila bignoniiflora occurring frequently. Duma florulenta often forms a shrub layer. The ground stratum ranges from sparse to dense and is dominated by perennial grasses and sedges. Species such as Cyperus victoriensis, Dichanthium fecundum, Paspalidium jubiflorum and Sporobolus mitchellii are common. Occurs on levees and banks of larger channels on broader braided alluvial plains. Soils very deep, brown or grey clays with sand and silt bands common in profile. Riverine. (BVG1M: 16a).

Fire management guidelines SEASON: Various (wet season or winter). INTENSITY: Low. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Aim to exclude fire by fuel reduction in adjacent vegetation communities where possible. Undertake partial burns when necessary to reduce fuel loads and protect against severe wildfire. Burn with high soil moisture (i.e., after rain/storms) or in winter when fire is more easily controlled. ISSUES: Rarely burns due to low fuel loads.
Comments 5.3.5: Asteraceae prevalent following favourable seasons. Heavily impacted by total grazing pressure. Habitat for feral pigs.
