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).
Supplementary description Dawson (1974), R2, R5 (LU 89, 90); Boyland (1984), 18b; Neldner (1984), 61a (79)
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.
