Regional ecosystem details for 10.9.8

Regional ecosystem 10.9.8
Vegetation Management Act class Of concern
Wetlands Not a Wetland
Biodiversity status Of concern
Extent in reserves This regional ecosystem is now mapped as 10.5.7.
Short description Archidendropsis basaltica low open woodland on Cretaceous sediments
Structure code Low Open Woodland
Description [RE not in use]²: This regional ecosystem is now mapped as 10.5.7. Archidendropsis basaltica dominates the very sparse small tree layer. Lysiphyllum carronii and Acacia excelsa are often present in the canopy. There are usually scattered shrubs or sometimes there is a very sparse shrub layer. The ground layer is very sparse. Occurs on undulating terrain with sandy soil to sandy clay soil over clay on Cretaceous sediments. Not a Wetland. (BVG1M: 27a).

Vegetation communities in this regional ecosystem include:
10.9.8x1: [RE not in use]²: This regional ecosystem is now mapped as 10.5.7. Flindersia maculosa or Atalaya hemiglauca as scattered trees to very sparse small tree layer. Ground consists of scattered forbs and grasses. Occurs on undulating terrain with shallow clay soil. Not a Wetland. (BVG1M: 27a).
Fire management guidelines SEASON: Wet to mid-dry season. Avoid late dry (August -September) as intensity will be too high (August -September). INTENSITY: Low. INTERVAL: 6-10 years, but will depend on seasonal conditions and grazing pressure. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: These communities generally have sparse ground layer. Will only burn following irregular high rainfall events. Fire is not generally applied directly to acacia dominated communities, but to surrounding fire-adapted communities in order to create a landscape mosaic of burnt/unburnt areas to mitigate against wildfire. Ensure fires are patchy. ISSUES: Acacias are fire sensitive and may be killed by high intensity or too frequent fire.
Comments 10.9.8: Similarities to map unit M4 in RE 10.3.27 and M4b in 10.3.6. Archidendropsis basaltica is more commonly found as an understorey species in Eucalyptus brownii, E. populnea or E. melanophloia woodlands but occasionally occurs as a dominant. Restricted ecosystem only known from near Barcaldine. The soils are highly dispersible and susceptible to sheet and rill erosion. Potential threats to this ecosystem are mainly from tree clearing, high susceptibility to salinity, weed infestation, over grazing and soil erosion. It is recommended that grazing be restricted to very short periods after the wet-season. The native pasture under the tree canopy in this regional ecosystem tends to have reasonable nutritive value but low bulk.

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.

2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
