Regional ecosystem details for 2.3.50
| Regional ecosystem | 2.3.50 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Riverine |
| Biodiversity status | Of concern |
| Subregion | 4, 6, 5, 3, 2, (7), (9), (8), (1), (1.3), (4.5), (1.4), (9.3), (9.1), (4.6) |
| Estimated extent1 | Pre-clearing 81000 ha; Remnant 2021 81000 ha |
| Short description | Waterholes, bare sand and rock in the channels of major watercourses |
| Structure code | Bare |
| Description | Waterholes, bare sand and rock. Associated woody species include Eucalyptus camaldulensis, Melaleuca spp., E. microtheca and Barringtonia acutangula. Aquatic vegetation, grasses, forbs and sedges may occur. Occurs in the channels of major watercourses. Riverine. (BVG1M: 16d). Vegetation communities in this regional ecosystem include: 2.3.50a: Bare sand and rock with scattered shrubs and patches of grasses, forbs and sedges. Occurs in the channels of major watercourses. Riverine. (BVG1M: 16d). 2.3.50b: Waterholes in active stream channels, occasionally with scattered aquatic vegetation. A variable wooded fringe commonly occurs, including Eucalyptus camaldulensis, Melaleuca spp., E. microtheca and Barringtonia acutangula. Seasonal to permanent. Occurs in the active channels of major watercourses. Riverine. (BVG1M: 16d). |
| Protected areas | Rungulla NP, Staaten River NP, Errk Oykangand NP (CYPAL) |
| Special values | 2.3.50b: Important sites for feeding and movement of birds, fish and reptiles. Potential habitat for Pristis pristis (freshwater sawfish), Elseya lavarackorum (Gulf snapping turtle) and Malurus coronatus (purple-crowned fairy wren). |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not actively target for burning. Maintain mosaic of time since burnt and unburnt patches in surrounding fire-adapted landscape to mitigate impacts of unplanned fire. ISSUES: These do not necessarily readily burn because ground fuels are sparse. Riparian areas contain important habitat for fauna. |
| Comments | 2.3.50a: Was previously mapped as 2.3.24x11. 2.3.50b: Was previously mapped as 2.3.24x12. Subject to degradation from high total grazing pressure. |
