Estimated extent1 Pre-clearing 18000 ha; Remnant 2021 18000 ha
Short description Corymbia leichhardtii and/or Corymbia lamprophylla and/or Eucalyptus exilipes woodland on the perimeter of sandy plateaus
Structure code Woodland
Description Corymbia leichhardtii and/or Corymbia lamprophylla and/or Eucalyptus exilipes woodland, occasionally with Eucalyptus xanthoclada and Eucalyptus similis. A variable mixed shrub layer usually occurs. The ground layer is dominated by Triodia spp. and tussock grasses. Occurs on flat to undulating terrain on the perimeter of sand plateau with shallow duplex soil on stripped part of Cainozoic sandplain. Not a Wetland. (BVG1M: 18a).
Protected areas White Mountains NP, White Mountains RR
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 10.7.9: Potential threat to this ecosystem is mainly from inappropriate fire regimes. The soils are shallow with low water holding capacity and low fertility. Plant growth is seasonal and pasture productivity is low. There are few palatable species and their cover is sparse.
