Regional ecosystem details for 6.7.14
| Regional ecosystem | 6.7.14 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 10, 8, 9, 11, (6), (4.4), (5.5), (5.6), (5.9), (5.2), (5), (5.8) |
| Estimated extent1 | Pre-clearing 975000 ha; Remnant 2021 948000 ha |
| Short description | Acacia clivicola +/- eucalypt spp. open shrubland on crests and tops of lateritic residuals |
| Structure code | Open Shrubland |
| Description | Acacia clivicola open shrubland, commonly with Hakea collina. A. aneura, Corymbia terminalis, C. blakei and Eucalyptus exserta are common emergents, particularly in the north-west. Other low shrubs may occur. The ground cover is typically grasses and forbs. Occurs on undulating plains and crests of dissected tablelands, formed on dissected Tertiary land surface (commonly Glendower Formation). Associated soils are very shallow, acidic, loam and clay-loam lithosols. Exposed rock covers large areas in this unit, and ironstone gravel or silcrete often occurs at the surface. Not a Wetland. (BVG1M: 24a). |

| Protected areas | Idalia NP, Currawinya NP, Hell Hole Gorge NP, Mariala NP, Welford NP |
| Special values | 6.7.14: Habitat for threatened plant species including Hakea maconochieana and Rhaphidospora bonneyana. |
| Fire management guidelines | SEASON: Various (wet season or winter). INTENSITY: Low to moderate. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Aim to exclude fire by fuel reduction in adjacent vegetation communities where possible. Undertake partial burns when necessary to reduce fuel loads and protect against severe wildfire. Burn with high soil moisture (i.e., after rain/storms) or in winter. ISSUES: Some Acacias can be fire sensitive (A. shirleyi, A. aneura) and may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems. |
