| Short description | Corymbia leichhardtii woodland on sand plains |
| Structure code | Woodland |
| Description | Corymbia leichhardtii woodland, commonly with Corymbia brachycarpa. Eucalyptus chartaboma, Eucalyptus shirleyi, Lysicarpus angustifolius and Callitris glaucophylla all occasionally occur in the canopy. A secondary tree layer, composed mostly of canopy species, is usually present. A variable shrub layer usually occurs. Tussock grass ground layer, commonly with Triodia pungens. Occurs on flat to gently sloping terrain usually on perimeter of sandplain plateaus often with shallow duplex soils. Not a Wetland. (BVG1M: 18a). Vegetation communities in this regional ecosystem include: 10.5.10x1: Corymbia lamprophylla low woodland with second tree layer of C. lamprophylla and Lysicarpus angustifolius. Prominent shrub layer including Acacia leptostachya, Calytrix microcoma, Jacksonia rhadinoclona, Grevillea sessilis and Labichea rupestris. Ground layer dominated by Triodia pungens. Occurs on small red sand plateaus adjoining dissected sandstone ranges. Not a Wetland. (BVG1M: 18a). |

| Special values | 10.5.10: Habitat for near threatened plant species Acacia spania. |
| Fire management guidelines | SEASON: Wet to mid-dry season while soil retains moisture. INTENSITY: Low to occasional moderate. INTERVAL: Interval will depend on need for burning, seasonal conditions and grazing pressure. Approximately 5-10 years. Do not burn during drought years. Concentrate burning during wet years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Due to the typically sparse nature of the spinifex in these ecosystems, there is rarely enough fuel load to burn. Patchy burns are preferred. Mosaic 50-80% of area targeted. Burn under conditions of good soil moisture and when plants are actively growing. Burns during dry periods may leave areas of soil exposed, leading to erosion. ISSUES: Spinifex responds to low intensity burning following the first summer rains. De-stock burnt spinifex areas for many months in good seasons or several growing seasons in a run of dry years. |
| Comments | 10.5.10: Widespread. Threatened by inappropriate fire regimes. 10.5.10x1: Only known from White Mountains NP. |
