| Regional ecosystem | 9.12.23 |
|---|---|
| Vegetation Management Act class | Least concern |

| Biodiversity status | No concern at present |
| Subregion | 4 |
| Estimated extent1 | Pre-clearing 39000 ha; Remnant 2021 39000 ha |
| Short description | Eucalyptus drepanophylla or E. crebra, Corymbia leichhardtii and C. lamprophylla low open woodland on igneous rocks |
| Structure code | Low Open Woodland |
| Description | Low open woodland to woodland of Eucalyptus drepanophylla (grey ironbark) or E. crebra (narrow-leaved ironbark), Corymbia leichhardtii (yellowjacket) and C. lamprophylla (shiny-leaved bloodwood) +/- C. dallachiana (Dallachy's gum). An open low sub-canopy can occur and include canopy species, Bursaria incana (prickly pine), Persoonia falcata and Grevillea glauca (bushman's clothes peg). The shrub layer is absent to open and is dominated by Acacia leptostachya (slender wattle), Petalostigma pubescens (quinine) and Grevillea glauca. Acacia wickhamii subsp. cassitera, Dodonaea lanceolata (currantbush) and Xanthorrhoea johnsonii (grass-tree) may also be present in a distinct lower shrub layer. The ground layer is dominated by Triodia spp. (spinifex) or Themeda triandra (kangaroo grass). Occurs on hills on igneous rocks. Not a Wetland. (BVG1M: 13c). |
| Special values | 9.12.23: Potential habitat for NCA listed species: Acacia longipedunculata, Corchorus subargenteus, Marsdenia brevifolia, Solanum graniticum. |
| Fire management guidelines | SEASON: Wet to mid-dry season while soil retains moisture. INTENSITY: Low to occasional moderate. INTERVAL: Interval will depend on need for burning, seasonal conditions and grazing pressure. Approximately 5-10 years. Do not burn during drought years. Concentrate burning during wet years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Patchy burns are preferred. Mosaic 50-80% of area targeted. Burn under conditions of good soil moisture and when plants are actively growing. Burns during dry periods may leave areas of soil exposed, leading to erosion. ISSUES: Establishment of areas of long unburnt vegetation will maintain a diversity of habitat. Spinifex responds to low intensity burning following the first summer rains. De-stock burnt spinifex areas for many months in good seasons or several growing seasons in a run of dry years. |
| Comments | 9.12.23: Occurs south of Paluma in the south-east of the bioregion. |
