| Short description | Eucalyptus populnea open woodland on sand plains |
| Structure code | Woodland |
| Description | Eucalyptus populnea woodland, commonly with Corymbia dallachiana. Corymbia plena, Corymbia plena, Corymbia terminalis, Atalaya hemiglauca and Eucalyptus melanophloia occasionally occur in the canopy. A secondary tree layer is usually present and commonly contains Acacia excelsa, Acacia sericophylla and Eucalyptus populnea. A variable shrub layer dominated by Eremophila mitchellii is usually present. Ground layer of Triodia pungens and tussock grasses. Occurs widely on sandy soils in the south of the bioregion. Not a Wetland. (BVG1M: 17a). |
| Protected areas | Cudmore RR, Cudmore (Limited Depth) NP |
| Special values | 10.5.12: Potential habitat for NCA listed species: Cerbera dumicola. |
| 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 | 10.5.12: Threatened by inappropriate fire regimes. Naturalised species associated with this regional ecosystem include *Cenchrus ciliaris, which may dominate the ground layer. |
