| Short description | Eucalyptus melanophloia woodland to open woodland or Lysiphyllum carronii low open woodland on calcareous sandstones |
| Structure code | Woodland |
| Description | [RE not in use]²: Refer to vegetation communities for new mapping. Eucalyptus melanophloia dominates the very sparse tree layer on upper slopes of low rises and Lysiphyllum carronii low open woodland. Occurs on mid to lower slopes with shallow brown to red neutral or alkaline duplex soils formed on calcareous sandstones. Not a Wetland. (BVG1M: 17b). Vegetation communities in this regional ecosystem include: 10.9.5a: [RE not in use]²: This vegetation community is now mapped as 10.5.11. Eucalyptus melanophloia dominates the very sparse tree layer. Lysiphyllum carronii and Atalaya hemiglauca occur as scattered small trees. Carissa lanceolata is often dominate the very sparse shrub layer and Hakea leucoptera is usually present and sometimes dominant in a very sparse tall shrub layer. Bothriochloa ewartiana dominates the very sparse to sparse ground layer. Occurs on upper slopes of low rises with shallow brown to red neutral or alkaline duplex soils formed on calcareous sandstones. Not a Wetland. (BVG1M: 17b). 10.9.5ax1: [RE not in use]²: This regional ecosystem is now mapped as 10.5.11. Eucalyptus whitei dominates the very sparse tree layer. Themeda triandra and Dichanthium sericeum can dominate the ground layer. Occurs on gently undulating to undulating terrain with clay soil with or without shallow sandy cover. Not a Wetland. (BVG1M: 17b). 10.9.5b: [RE not in use]²: This vegetation community is now mapped as 10.5.7. Lysiphyllum carronii dominates the very sparse small tree layer. Carissa lanceolata is present as scattered shrubs or is dominant in a very sparse shrub layer. Bothriochloa ewartiana with Sporobolus actinocladus are usually present as codominants in the ground layer. Occurs on mid to lower slopes with shallow brown to red neutral or alkaline duplex soils formed on calcareous sandstones. Not a Wetland. (BVG1M: 27a). |

| 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 | 10.9.5: Restricted to Ulcanbah area. Subject to pasture development, buffel grass invasion and infrastructure development. The soils are highly dispersible and susceptible to sheet and rill erosion. Bare soil tends crust readily after rain leading to reduced infiltration and increased runoff. Also, evaporation is greater from bare soil resulting in salt concentration at the surface. Potential threats to this ecosystem are mainly from tree clearing, high susceptibility to salinity, weed infestation particularly Parthenium, over grazing and soil erosion. 10.9.5a: Rare vegetation community only known from near Ulcanbah and found on upper slopes. There are small patches of E. brownii associated with 10.9.5a. Further survey of this E. brownii component is desirable. 10.9.5b: Rare ecosystem only known from near Ulcanbah. |
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.
