Regional ecosystem details for 11.9.6

Regional ecosystem 11.9.6
Vegetation Management Act class Endangered
Wetlands Not a Wetland
Biodiversity status Endangered
Subregion 25, 31, (27), (26)
Estimated extent1 Pre-clearing 15000 ha; Remnant 2021 300 ha
Short description Acacia melvillei +/- A. harpophylla open forest on fine-grained sedimentary rocks
Structure code Open Forest
Description Open forest dominated by Acacia melvillei with or without Acacia harpophylla, and with or without Eucalyptus populnea. Ground cover may be sparse. Occurs on Cainozoic to Proterozoic consolidated fine-grained sediments on gently undulating landscapes on more or less horizontally bedded fine grained sedimentary rocks. It may include some areas occurring on clay plains. Not a Wetland. (BVG1M: 25a).

Vegetation communities in this regional ecosystem include:
11.9.6a: [RE not in use]²: This vegetation is now mapped as 11.9.6. Acacia melvillei open forest. Occurs on Cainozoic clay plains. Not a Wetland. (BVG1M: 25a).
Supplementary description Fensham and Fairfax: (1997)
Special values 11.9.6: Potential habitat for NCA listed species: Homopholis belsonii.
Fire management guidelines INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Maintain fire management of surrounding country so that wildfires will be very limited in extent. Frequent fire at the edge of this RE keeps fuel loads low. Protection from fire is necessary. ISSUES: Casuarina cristata is fire sensitive, although germination can be good in bare areas. Brigalow is soft-seeded, so germination is not promoted by fire. Buffel grass invasion will increase risk from fire. High intensity fires will cause damage to overstorey. Grazing may be an option for reducing fuel loads where exotic grass such as buffel have invaded.
Comments 11.9.6: Was previously mapped as 11.9.6a. Cleared for cropping.

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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
