Regional ecosystem details for 6.5.9

Regional ecosystem 6.5.9
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status Of concern
Subregion 6, 4, (11.26), (4.4)
Estimated extent1 Pre-clearing 282000 ha; Remnant 2021 95000 ha
Short description Acacia aneura +/- Eucalyptus populnea, E. melanophloia low woodland on sand sheets in the north
Structure code Low Woodland
Description Acacia aneura low woodland, with Eucalyptus melanophloia and/or E. populnea emergents. Other trees such as Corymbia clarksoniana, Brachychiton populneus, Archidendropsis basaltica, Ventilago viminalis, Alectryon oleifolius and Acacia excelsa frequently occur as emergents or in the tree canopy. Tall shrubs may occur, including Archidendropsis basaltica, Psydrax oleifolia, Eremophila longifolia, E. mitchellii and Geijera parviflora. The ground layer is dominated by Thyridolepis mitchelliana at higher tree and shrub densities while Aristida spp. become increasingly abundant and dominant in more open areas. Other species include Aristida calycina var. praealta, Digitaria brownii, Eragrostis lacunaria, Enteropogon acicularis and Ancistrachne uncinulata. Occurs on gently undulating sand sheets formed from Quaternary deposits over the Tertiary land surface in the north of the bioregion. Associated soils are deep sandy red earths. Not a Wetland. (BVG1M: 23a).

Fire management guidelines SEASON: Various (wet season or winter). INTENSITY: Low to moderate. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Aim to exclude fire by fuel reduction in adjacent vegetation communities where possible. Undertake partial burns when necessary to reduce fuel loads and protect against severe wildfire. Burn with high soil moisture (i.e., after rain/storms) or in winter. ISSUES: Acacia aneura may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems.
Comments 6.5.9: Confined to the north east part of the region where it often occurs in close proximity with Brigalow Belt regional ecosystems such as Acacia harpophylla woodland (11.9.11). Extensive areas of this regional ecosystem have been cleared and converted to exotic pasture. Emergent eucalypts may form open woodland (100 trees / ha).

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.
