| Regional ecosystem | 3.5.30 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Extent in reserves | This regional ecosystem is not mapped. |
| Short description | Themeda arguens and Dichanthium sericeum closed tussock grassland on low undulating rises |
| Structure code | Closed Tussock Grassland |
| Description | [RE not in use]²: This regional ecosystem is not mapped. Themeda arguens dominates the dense ground layer. Fimbristylis spp. And Panicum spp. Frequently occur below the tall grass canopy. Dichanthium sericeum subsp. Sericeum (Queensland blue grass) and Capillipedium parviflorum (scented top) are often subdominant. Emergent low trees and shrubs occur very sporadically. Occurs on low undulating rises. Not a Wetland. (BVG1M: 32a). Vegetation communities in this regional ecosystem include: 3.5.30x1: [RE not in use]²: This proposed new regional ecosystem is now mapped as 3.5.29. Imperata cylindrica (blady grass) dominates the dense ground layer (1-1.6m tall). At some sites, Mnesithea rottboellioides (northern canegrass) may be codominant, and near the Nesbit River, Arundinella setosa is dominant. Fimbristylis spp. and Scleria spp. frequently occur below the tall grass canopy. Emergent trees (2-6m tall) are extremely rare. Occurs on coastal plains. Not a Wetland. (BVG1M: 32b). 3.5.30x3: [RE not in use]²: This proposed new regional ecosystem is now mapped as 3.5.29. Themeda triandra (kangaroo grass) dominates the mid-dense ground layer (10-60cm tall), which varies in height depending on exposure to the prevailing winds. Heteropogon contortus (black speargrass), Cassytha filiformis and Zornia muriculata are frequently present, but contribute only a small proportion of the biomass. Scattered shrubs may be present, but are generally windsheared and do not emerge much above the ground layer. Occurs on coastal headlands. Not a Wetland. (BVG1M: 32a). |

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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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