Regional ecosystem details for 1.11.8
| Regional ecosystem | 1.11.8 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 3, (2.8), (2.2), (1), (2), (4.3), (4.2) |
| Estimated extent1 | Pre-clearing 30000 ha; Remnant 2021 30000 ha |
| Short description | Terminalia aridicola and/or Corymbia aspera low open woodland to low woodland, usually with vine-scrub species, on rock outcrops |
| Structure code | Low Woodland |
| Description | Terminalia aridicola and/or Corymbia aspera low open woodland to low woodland, often with Brachychiton collinus, Ficus spp., Alphitonia spp. and Trema tomentosa with mid-dense shrub layer of Acacia spp. and/or Calytrix brownii and ground layer of mixed tussock grasses and Triodia spp. Calytrix brownii may be dominant on exposed rock faces. Occurs on rock outcrops on hills and ranges on strongly folded siliceous sedimentary and metamorphic pre-Cambrian rocks. Not a Wetland. (BVG1M: 27c). |
| Special values | 1.11.8: Potential habitat for NCA listed species: Eucalyptus nudicaulis. |
| Fire management guidelines | SEASON: Storm season to early dry season. INTENSITY: Low to moderate. INTERVAL: 4 - 10 years. Ensure some areas are long (10-20 years) unburnt. Adjust intervals/frequency according to rainfall-drought cycles, fuel accumulation and previous fire history. INTERVAL_MIN: 4. INTERVAL_MAX: 20. STRATEGY: Ensure burns are undertaken across the landscape at a range of frequencies to create a mosaic of times since fire. Apply numerous small burns every year to achieve a mosaic and reduce risks of wildfire across vast areas of the landscape. Maintain burnt areas < 20%. ISSUES: Key driver of this community is protection from fire provided by exposed rock. The larger the fire refuge the richer the community that develops. Rainfall is a major factor affecting spinifex growth, such that a very wet year or a series of wet years may boost the spinifex fuel load leading to the possibility of extensive wildfire in subsequent years. Mixed shrubby woodlands contain fire-sensitive species and tend to grow in fire-sheltered areas. |
| Comments | 1.11.8: Key driver of this community is protection from fire provided by exposed rock. The larger the fire refuge the richer the community that develops. This vegetation community was previously mapped as 1.11.2x4. |
