Regional ecosystem details for 2.3.52
| Regional ecosystem | 2.3.52 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Riverine |
| Biodiversity status | Of concern |
| Subregion | 2, 7, (1.4), (1), (1.3), (1.2) |
| Estimated extent1 | Pre-clearing 29000 ha; Remnant 2021 29000 ha |
| Short description | Melaleuca spp., Eucalyptus camaldulensis, Lophostemon grandiflorus and Livistona rigida in mixed woodlands fringing major spring-fed watercourses |
| Structure code | Woodland |
| Description | Mixed woodland, including combinations of the species Melaleuca leucadendra, Melaleuca fluviatilis, Eucalyptus camaldulensis, Lophostemon grandiflorus, Livistona rigida and Nauclea orientalis. Occasional canopy species include Ficus racemosa, Pandanus sp., Eucalyptus microtheca and Melaleuca argentea. The ground layer is sparse, with tussock grasses and forbs. Occurs on fringes of major, spring-fed watercourses extending from the Northwest Highlands bioregion. Riverine. (BVG1M: 22c). |
| Protected areas | Lawn Hill (Widdallion) RR, Boodjamulla (Lawn Hill) NP, Lawn Hill (Creek) RR, Lawn Hill (Arthur Creek) RR |
| Special values | 2.3.52: Significant provincial refuges for fauna. Includes permanent, spring-fed water with high habitat values for aquatic and other species. Potential habitat for Pristis pristis (freshwater sawfish), Elseya lavarackorum (Gulf snapping turtle) and Malurus coronatus (purple-crowned fairy wren). |
| Fire management guidelines | SEASON: Burn in the wet season or very soon after. INTENSITY: Low to moderate. INTERVAL: Determine by assessment of fuel accumulation, previous fire history and wildfire risk. 1-5 years broad interval range. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: 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. Overgrazing can reduce fuel loads and give woody species a competitive advantage. Riparian areas contain important habitat for fauna. |
| Comments | 2.3.52: Was previously mapped as 2.3.26x1b. Subject to degradation from high total grazing pressure. |
