| Estimated extent1 | Pre-clearing 58000 ha; Remnant 2021 57000 ha |
| Short description | Ephemeral sparse tussock grassland ground below scarps |
| Structure code | Open Tussock Grassland |
| Description | Ephemeral sparse ground layer with chenopods to bare ground with occasional emergent shrubs or small trees such as blackwood (Acacia argyrodendron) and /or false sandalwood (Eremophila mitchellii). Sclerolaena spp. and Enchylaena tomentosa usually dominate the very sparse small shrub layer. There are occasional emergent shrubs or small trees such as Acacia argyrodendron and/or Eremophila mitchellii. The ground layer is very sparse. Occurs on largely bare areas on stripped lateritic surfaces. Not a Wetland. (BVG1M: 31b). Vegetation communities in this regional ecosystem include: 10.7.13x1: Triodia pungens hummock grassland. Emergent trees and shrubs commonly occur and include: Corymbia dallachiana, Eucalyptus whitei, Eucalyptus persistens and Acacia spp. Occurs on undulating terrain with skeletal soil on laterite. Not a Wetland. (BVG1M: 31b). |

| Fire management guidelines | SEASON: Do not target for burning. INTENSITY: Do not target for burning. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not target for burning. Most species are fire sensitive. Burning in adjacent fire adapted communities will reduce risk of wildfire incursion. Ensure fire encroachment is limited. Burns in adjacent vegetation, implemented in late wet to early dry season, may limit fire incursion into sensitive vegetation. ISSUES: Unlikely to burn due to generally sparse nature. Rarely enough fuel load to burn in any case. |
| Comments | 10.7.13: Rare ecosystem with restricted distribution on the western edge of the bioregion, east of Muttaburra. The soils are shallow with low water holding capacity and low fertility. Plant growth is seasonal and pasture productivity is low. There are few palatable species and their cover is sparse. Potential threat to this ecosystem is mainly from cattle and sheep grazing. |
