| Short description | Eucalyptus camaldulensis +/- Corymbia polycarpa, Melaleuca viridiflora woodland on abandoned stream channels and upper drainage areas in lateritic landscapes |
| Structure code | Woodland |
| Description | Eucalyptus camaldulensis woodland. A secondary tree layer may occur, including Corymbia polycarpa and Melaleuca viridiflora. A shrub layer may occur, including Acacia spp., Asteromyrtus symphyocarpa and Ficus opposita. The ground layer is primarily tussock grasses, including Pseudoraphis spinescens, Eulalia aurea and Chrysopogon oliganthus. Occurs on abandoned stream channels, sandy levees and upper drainage areas in lateritic landscapes, primarily associated with the Nicholson River. Sandy loam soils. Riverine. (BVG1M: 16a). Vegetation communities in this regional ecosystem include: 2.3.62a: Eucalyptus camaldulensis woodland. A shrub layer including Acacia spp., Asteromyrtus symphyocarpa and Ficus opposita commonly occurs. The ground layer is tussock grasses including Pseudoraphis spinescens, Chrysopogon oliganthus and Eulalia aurea. Occurs on abandoned stream channels and sandy levees, primarily associated with the Nicholson River. Sandy loam soils. Riverine. (BVG1M: 16a). 2.3.62b: Eucalyptus camaldulensis woodland, commonly with Corymbia polycarpa and/or Melaleuca viridiflora in the canopy or as a secondary tree layer. The ground layer is dominated by Eulalia aurea, commonly with Fimbristylis spp. Occurs on upper drainage areas in lateritic landscapes, subject to seepage from ferricrete surfaces. Sandy loam soils. Riverine. (BVG1M: 16a). |
| Special values | 2.3.62b: Supports plant growth well into the dry season. Provincial refuge for flora and fauna. |
| Fire management guidelines | SEASON: Burn in the wet season or very soon after. INTENSITY: Low to moderate. INTERVAL: Determine by assessment of fuel accumulation, previous fire history and wildfire risk. 1-5 years broad interval range. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Maintain mosaic of time since burnt and unburnt patches in surrounding fire-adapted landscape to mitigate impacts of unplanned fire. ISSUES: May contain important habitat for fauna. |
| Comments | 2.3.62: A rare vegetation community. 2.3.62a: A rare vegetation community. Was previously mapped as 2.3.26x1e. 2.3.62b: A rare ecosystem with limited extent. Was previously mapped as 2.3.26x2. |
