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.
