| Description | Eucalyptus thozetiana, Acacia harpophylla woodland. Occurs on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Lowlands and footslopes. Not a Wetland. (BVG1M: 25a). Vegetation communities in this regional ecosystem include: 11.11.19a: [RE not in use]²: This vegetation community is mapped as 11.11.19. Eucalyptus crebra and/or Acacia rhodoxylon +/- Corymbia dallachiana +/- Acacia catenulata woodland. Occurs on older volcanics (land zone 12). Not a Wetland. (BVG1M: 13c). |

| Protected areas | Blackwood NP, Narrien Range NP, Snake Range NP |
| 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 | 11.11.19: Was previously mapped as 11.11.19a. Extensively cleared for pasture. |
1 Estimated extent is from version 13 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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
