Short description Acacia harpophylla or A. argyrodendron low open forest with a secondary tree layer of Terminalia oblongata on deformed and metamorphosed sediments and interbedded volcanics
Structure code Open Forest
Description Acacia harpophylla shrubby open forest or A. argyrodendron shrubby low open forest or woodland. Terminalia oblongata, Eremophila mitchellii are common components in the understorey. Emergent Eucalyptus spp. may be present, especially E. populnea. Occurs on undulating rises and low hills often with distinct strike pattern formed on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Not a Wetland. (BVG1M: 25a).

Protected areas Nairana NP, Narrien Range NP, Blackwood NP, Snake Range NP
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 and 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. Avoid damage to Acacia trees from fires.

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.
