Regional ecosystem details for 1.7.4
| Regional ecosystem | 1.7.4 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Subregion | 3, (4.2) |
| Estimated extent1 | Pre-clearing 6000 ha; Remnant 2021 6000 ha |
| Short description | Triodia brizoides and/or T. molesta hummock grassland on ferricrete and on silcrete |
| Structure code | Hummock Grassland |
| Description | Triodia brizoides and/or Triodia molesta hummock grassland often with emergent shrubs of Acacia spp., Senna spp. and Eremophila spp. Occurs on ferricrete and on silcrete in the south of the bioregion. Not a Wetland. (BVG1M: 33b). |
| Fire management guidelines | SEASON: Storm season to early dry season. INTENSITY: Low with occasional moderate. INTERVAL: 4 - 10 years. Ensure patches of long-unburnt vegetation are left (>30 years). Adjust intervals/frequency according to rainfall-drought cycles, fuel accumulation and previous fire history. INTERVAL_MIN: 4. INTERVAL_MAX: 100. STRATEGY: Burning with good soil moisture should ensure a patchy mosaic of burnt and unburnt vegetation should occur. Burn < 20% of the landscape. ISSUES: Seasonal rainfall is a key driver of fuel and therefore fire extent and frequency. Adjust fire regime according to wet season. |
