| Short description | Corymbia citriodora woodland on coarse-grained sedimentary rocks |
| Structure code | Woodland |
| Description | Corymbia citriodora predominates and forms a distinct but discontinuous woodland to open forest. On rocky slopes, Eucalyptus crebra and C. hendersonii may be scattered throughout the canopy or locally abundant. On flats and footslopes, scattered E. crebra, C. clarksoniana and C. tessellaris may occur. Corymbia trachyphloia and E. cloeziana often occur on crests and plateaus while E. apothalassica and E. longirostrata sometimes occur in moister microhabitats. Scattered tall to low shrubs, such as Acacia leiocalyx, Acacia spp., Bursaria spinosa subsp. spinosa, Persoonia falcata, Alphitonia excelsa, Petalostigma pubescens and Xanthorrhoea johnsonii are usually present and sometimes form a conspicuous layer. The ground layer varies from sparse to moderately dense (depending on the rockiness) and is dominated by perennial grasses. Occurs on hills and ranges, particularly on colluvial lower slopes, formed from medium to coarse-grained sediments (usually sandstone). Associated soils are often texture contrast with a thin sandy or loamy surface horizon and some uniform sandy and lithosol soils. Not a Wetland. (BVG1M: 10a). Vegetation communities in this regional ecosystem include: 11.10.1a: Corymbia watsoniana +/- C. citriodora, +/- C. trachyphloia +/- C. hendersonii woodland. Occurs on hills and ranges, particularly on colluvial lower slopes, formed from medium to coarse-grained sediments (usually sandstone). Associated soils are often texture contrast with a thin sandy or loamy surface horizon and some uniform sandy and lithosol soils. Not a Wetland. (BVG1M: 12a). 11.10.1b: [RE not in use]²: This vegetation community is now mapped as 11.10.1. Eucalyptus mediocris woodland. Occurs on hills and ranges, particularly on colluvial lower slopes, formed from medium to coarse-grained sediments (usually sandstone). Associated soils are often texture contrast with a thin sandy or loamy surface horizon and some uniform sandy and lithosol soils. Not a Wetland. (BVG1M: 12a). 11.10.1c: [RE not in use]²: This vegetation is now mapped as 11.10.1. Eucalyptus fibrosa, Eucalyptus spp. woodland. Occurs on hills and ranges, particularly on colluvial lower slopes, formed from medium to coarse-grained sediments (usually sandstone). Associated soils are often texture contrast with a thin sandy or loamy surface horizon and some uniform sandy and lithosol soils. Not a Wetland. (BVG1M: 12a). 11.10.1d: Eucalyptus crebra woodland. Occurs on hills and ranges, particularly on colluvial lower slopes, formed from medium to coarse-grained sediments (usually sandstone). Associated soils are often texture contrast with a thin sandy or loamy surface horizon and some uniform sandy and lithosol soils. Not a Wetland. (BVG1M: 12a). |

| 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: Moderate to high. INTERVAL: 6-10 years (shorter intervals in north of bioregion: 3 - 7 years). INTERVAL_MIN: 3. INTERVAL_MAX: 10. STRATEGY: Burn less than 10-30% in any year. Burn surrounding vegetation under conditions of good soil moisture and when plants are actively growing throughout the year so that wildfires will be very limited in extent. Fire exclusion not necessary. ISSUES: Best protection from wildfires is probably the creation of a multi-aged mosaic in surrounding vegetation and perimeter burning. Planned burns have traditionally been carried out in the winter dry season; further research required. |
| Comments | 11.10.1: Regional Ecosystem 11.10.1b and 11.10.1c has been amalgamated into this RE. This regional ecosystem has been extensively logged which has resulted in a decrease in the number of trees in the larger size classes which included many important habitat trees. |
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.
