| Structure code | Woodland |
| Description | Eucalyptus melanophloia woodland, usually with Corymbia dallachiana and commonly with Eucalyptus brownii. Shrub layer of Acacia spp., Carissa lanceolata and Eremophila spp. Tussock grass ground layer, occasionally with Triodia pungens. Occurs on sandy alluvial fans with yellow earth and duplex soils formed from outwash from sandstone hills. Not a Wetland. (BVG1M: 17b). Vegetation communities in this regional ecosystem include: 10.3.28a: Eucalyptus melanophloia woodland, usually with Corymbia dallachiana and commonly with Eucalyptus brownii. Shrub layer of Acacia spp., Carissa lanceolata and Eremophila spp. Tussock grass ground layer, occasionally with Triodia pungens. Occurs on sandy alluvial fans. Contains Palustrine. (BVG1M: 17b). 10.3.28b: [RE not in use]²: This vegetation community is now mapped as 10.5.4. Eucalyptus crebra woodland, commonly with Corymbia plena. Tussock grass ground layer. Occurs on sandy alluvial fans. Not a Wetland. (BVG1M: 18b). |
| Supplementary description | Thompson and Turpin (in prep), E15Ay, E2b |
| Protected areas | Cudmore (Limited Depth) NP, Cudmore RR |
| Special values | 10.3.28: Habitat for relatively uncommon species Velleia macrocalyx known from only seven Herbarium records in the DEU (total of 14 records for Queensland). |
| Fire management guidelines | SEASON: Wet to mid-dry season while soil retains moisture. INTENSITY: Low to occasional moderate. INTERVAL: Interval will depend on need for burning, seasonal conditions and grazing pressure. Approximately 5-10 years. Do not burn during drought years. Concentrate burning during wet years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Patchy burns are preferred. Mosaic 50-80% of area targeted. Burn under conditions of good soil moisture and when plants are actively growing. Burns during dry periods may leave areas of soil exposed, leading to erosion. ISSUES: Grazing can impact heavily and combined with low rainfall fuel loads will be low making burning difficult. Can be advantageous to burn in year following good rains to manage currant bush and false sandalwood. |
| Comments | 10.3.28: The top soils on the upper slopes are susceptible to sheet erosion while on the lower slopes the top soils are deeper and have better water-holding capacity but are subject to flooding and salting. Revegetation after loss of top soil and exposure of the clayey subsoil is expected to be difficult and very slow. Nutrient levels, particularly phosphorus are very low. Subject to widespread pasture degradation, and to clearing for pasture development. 10.3.28b: Restricted to the northern parts of the bioregion. |
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.
