Regional ecosystem details for 2.5.30
| Regional ecosystem | 2.5.30 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 4, (3), (9), (5), (8), (9.1) |
| Estimated extent1 | Pre-clearing 388000 ha; Remnant 2021 388000 ha |
| Short description | Melaleuca spp., Lysiphyllum cunninghamii and Terminalia spp. in mixed low woodlands on Tertiary sand sheets |
| Structure code | Low Woodland |
| Description | Mixed low woodland, including combinations of the species Melaleuca citrolens, Lysiphyllum cunninghamii, Terminalia spp. and M. stenostachya. Occasional canopy species include Eucalyptus pruinosa, Melaleuca viridiflora and Grevillea spp. Emergent Corymbia spp. may occur. A sparse, variable shrub layer may occur. The ground layer is tussock grasses, including Schizachyrium fragile, Aristida spp. and Chrysopogon fallax. Occurs on broad, level to gently undulating Tertiary sand sheets immediately south of the Gilbert River delta. Grey to brown sandy loams soils. Not a Wetland. (BVG1M: 21b). |
| Fire management guidelines | SEASON: Commence soon after wet season when just dry enough to carry fire. Occasional storm burns; high intensity fires caused by lightning are a feature of this system. INTENSITY: Low to moderate. INTERVAL: 1-3 years or longer, 3-5 years in the south (i.e., latitudes below Karumba) and in riparian areas. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Maintain a landscape mosaic of time since fire to break up fuel continuity through the landscape and to avoid impact of late season wildfire. Ensure good soil moisture. ISSUES: Repeat early season burns where there are overabundant seedlings and saplings is not recommended. |
| Comments | 2.5.30: Significant increase in canopy species richness compared to 2.5.17. Six Terminalia species recorded in this regional ecosystem. Was previously mapped as 2.5.15x3. |
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.
