Description Eucalyptus melanophloia and/or E. orgadophila woodland to open woodland. Other tree species occasionally present as subdominants include Corymbia erythrophloia, Eucalyptus populnea or Corymbia dallachiana. Occurs on rises on undulating plains with cracking clay or texture contrast soils. Not a Wetland. (BVG1M: 17b).

Vegetation communities in this regional ecosystem include:
11.9.2a: [RE not in use]²: This vegetation community is now mapped as 11.9.2. Eucalyptus melanophloia shrubby woodland and/or E. orgadophila grassy woodland. Shrub and low tree species include Acacia spp., Archidendropsis basaltica and Carissa ovata. RE is defunct. Not a Wetland. (BVG1M: 10a).

Special values 11.9.2: Potential habitat for NCA listed species: Solanum elachophyllum.
Fire management guidelines SEASON: Late wet to early dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Low to moderate. INTERVAL: 6-10 years. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Restrict to less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. Sometimes a small amount of wind may move the fire front quickly so that burn intensity is not too severe to destroy habitat trees. ISSUES: Burn interval for conservation purposes will differ from that for grazing purposes; the latter being much shorter. Management of this vegetation type should be based on maintaining vegetation composition, structural diversity, fauna habitats (in particular hollow-bearing trees and logs) and preventing extensive wildfire. Maintaining a fire mosaic will help ensure protection of habitat and mitigate against wildfires. Fire can control shrub invasives (e.g., Eremophila spp. and A. stenophylla in the red soil country in particular). Fire will also control cypress. Low to moderate intensity burns with good soil moisture are necessary to minimise loss of hollow trees. Avoid burning riparian communities as these can be critical habitat for some species. Planned burns have traditionally been carried out in the winter dry season; further research required.
Comments 11.9.2: Intergrades with grasslands (11.9.3) in many areas. Was previously mapped as 11.9.2a. This regional ecosystem has been subject to periodic canopy dieback due to drought in parts of central Queensland. 11.9.2a: This regional ecosystem has been subject to periodic canopy dieback due to drought in parts of central Queensland.

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.
