Short description Acacia tephrina woodland on alluvial plains
Structure code Low Woodland
Description Acacia tephrina low woodland to low open woodland. Other Acacia spp. may occur, including Acacia oswaldii and Acacia salicina. A low shrub layer of Eremophila mitchellii, Carissa ovata or Scaevola spinescens may occur, with a usually sparse ground layer of Dactyloctenium radulans, Astrebla squarrosa, Leptochloa spp., Dichanthium spp., Paspalidium caespitosum, Panicum spp., Eragrostis spp. and Sporobolus spp. Occurs on older floodplain complexes on Cainozoic alluvial plains. Associated soils are usually grey calcareous or saline clays with gilgai microrelief. Not a Wetland. (BVG1M: 27a).

Fire management guidelines INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not target for fires. Can tolerate only very early dry season fires, under mild conditions, that trickle along the ground layer. Control fuel loads in the surrounding vegetation. ISSUES: Brigalow, Gidgee, Boree, Blackwood are only tolerant of mild fires trickling underneath, and can be damaged or killed by moderate to high intensity fires. Exotic grasses, such as Buffel grass, carry intense fires into these communities and can cause tree deaths. There should be no damage to Acacia trees from fires.
Comments 11.3.34: This regional ecosystem represents a coastal population of the tree species Acacia tephrina which is disjunct from its more widespread occurrence in western Queensland. Extensively cleared for cropping or modified by total grazing pressure.

1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
