Regional ecosystem details for 9.3.7
| Regional ecosystem | 9.3.7 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Palustrine |
| Biodiversity status | No concern at present |
| Subregion | 5, 6, 2, 4, (2.9) |
| Estimated extent1 | Pre-clearing 11000 ha; Remnant 2021 11000 ha |
| Short description | Wetlands and seasonally inundated grasslands with a fringing open woodland of mixed Eucalyptus spp. on Tertiary surfaces |
| Structure code | Tussock Grassland |
| Description | Wetlands and seasonally inundated grasslands with a fringing open woodland of mixed Eucalyptus spp. varying between Eucalyptus platyphylla (poplar gum), E. leptophleba (Molloy red box), E. camaldulensis (river red gum) or E. tereticornis (bluegum), E. brownii (Reid River box) and Corymbia polycarpa (long-fruited bloodwood) with no mid layer and a ground layer dominated by sedges, aquatic grasses and grasses which are seasonally dependent. In some areas prone to less inundation shrublands of Melaleuca spp. can occur. Occurs on Tertiary surfaces, often formed against basalt flows. Palustrine. (BVG1M: 34d). |
| Protected areas | Blackbraes NP, Canyon RR, Girringun NP, Great Basalt Wall NP |
| Special values | 9.3.7: Includes both seasonal and permanent wetlands significant as feeding and breeding sites for water birds, and as drought refuge. |
| Fire management guidelines | SEASON: Do not burn deliberately. INTENSITY: Do not burn deliberately. Can occasionally tolerate low intensity fire. INTERVAL: Occasional. INTERVAL_MIN: 50. INTERVAL_MAX: 100. STRATEGY: Manage surrounding country when soil moisture is high; allow fire to occasionally carry into melaleuca community. ISSUES: Fringing forest can be damaged by fire. |
| Comments | 9.3.7: Distinguished from RE 9.3.4 by being on Tertiary surfaces, rather than Quaternary alluvial surfaces. Occurs in the central and southern parts of the bioregion. |
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.
