| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Extent in reserves | This regional ecosystem was wholly mapped in the Channel Country. |
| Short description | Astrebla squarrosa +/- A. pectinata +/- Iseilema spp. grassland on clay plains |
| Structure code | Open Tussock Grassland |
| Description | [RE not in use]²: This regional ecosystem was wholly mapped in the Channel Country. Astrebla squarrosa usually predominates with A. pectinata being co dominant, and together form a tussock grassland. Iseilema vaginiflorum and Aristida latifolia are frequent, and abundant in heavily grazed areas. Shrubs are very sparse and infrequent. Occurs on flat clay plains on the Winton plateau formed from Tertiary mudstones. Associated soils are moderately deep, grey cracking clays with strongly self mulching surfaces. Broad shallow gilgais common. Not a Wetland. (BVG1M: 30b). |

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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
