| Short description | Eucalyptus drepanophylla woodland on sandstone ranges |
| Structure code | Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 10.10.4. E. drepanophylla dominates the very sparse tree layer and Corymbia lamprophylla dominates the small tree layer. C. leichhardtii can be present in the canopy. Petalostigma banksii often dominates the shrub layer. Jacksonia ramosissima and Dodonaea dodecandra are usually present. Eriachne mucronata, Alloteropsis semialata and Schizachyrium fragile dominate very sparse ground layer. Occurs on slopes of rocky hills with skeletal soils to shallow sandy earths, often gravelly, on sandstone ranges. Not a Wetland. (BVG1M: 12a). |

| 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: Spinifex responds to low intensity burning following the first summer rains. De-stock burnt spinifex areas for many months in good seasons or several growing seasons in a run of dry years. Due to the typically sparse nature of the spinifex in these ecosystems, there is rarely enough fuel load to burn. |
| Comments | 10.10.3: A rare ecosystem which is difficult to map. Recorded in southern parts of subregion 2 and 4 along the Great Dividing Range. The soils are shallow with low water holding capacity and low fertility. The nature of the soils and the very sparse ground cover of plants renders this ecosystem highly susceptible to erosion. Degradation in the form of soil disturbance or reduction of ground cover will be difficult to reverse and therefore tree-clearing should not occur. Plant growth is seasonal and pasture productivity is low. There are few palatable species and their cover is very low. It is recommended that grazing be controlled by fencing out areas of land zone 10. Fire management requires consideration of the effect of the expected slow recovery rate of plant cover. Potential threat is mainly wildfire. |
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.
