Regional ecosystem details for 9.12.29
| Regional ecosystem | 9.12.29 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Subregion | 2, (2.9) |
| Estimated extent1 | Pre-clearing 5000 ha; Remnant 2021 5000 ha |
| Short description | Eucalyptus similis and E. shirleyi +/- E. crebra low open woodland on low granite hills with rocky outcrops |
| Structure code | Low Open Woodland |
| Description | Low open woodland to low woodland of Eucalyptus similis (yellowjacket) and E. shirleyi (silver-leaved ironbark) +/- E. crebra (narrow-leaved ironbark) (sens. lat.) +/- Acacia julifera (catkin wattle) +/- Erythrophleum chlorostachys (Cooktown ironwood). The shrub layer is absent to scattered shrubs including juveniles of the canopy species, Petalostigma banksii (smooth-leaved quinine), Grevillea glauca (bushman's clothes peg) and Terminalia aridicola (arid peach). The ground layer is grassy and dominated by Aristida spp. Occurs on rolling low hills with granite boulders and rocky outcrops on the foothills. Not a Wetland. (BVG1M: 13c). |
| Protected areas | Canyon RR |
| Fire management guidelines | SEASON: Early dry season and storm time. Timing of early dry season burns will vary depending on seasonal conditions; it may sometimes commence as early as March. Avoid burning August-October when south-easterly winds are typically strongest. INTENSITY: Low, with occasional moderate or high. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Apply mosaic across the landscape at a range of frequencies to create varying stages of post-fire response. ISSUES: These ecosystems contain shrubs that germinate after fire. Seedlings typically take a number of years to mature. Avoid repeated fires at short intervals and high intensity burns of broad areas. Leave areas of long unburnt vegetation to maintain a diversity of habitat for wildlife. Shrub species diversity will decline if areas are left long unburnt. |
| Comments | 9.12.29: Acacia julifera and some deciduous low woodland species are frequent. Occurs north of the Chudleigh Plateau in the south west of the bioregion. |
