Regional ecosystem 5.7.14
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status No concern at present
Subregion 1, 4, (4.2), (2), (10), (5)
Estimated extent1 Pre-clearing 36000 ha; Remnant 2021 36000 ha
Short description Acacia sibirica, Hakea eyreana +/- Acacia aneura +/- Eremophila freelingii open shrubland on sandstones
Structure code Open Shrubland
Description Acacia sibirica predominates and together with Hakea eyreana forms a very sparse canopy layer. Scattered emergent Acacia aneura and Corymbia terminalis are frequently present. A number of scattered shrubs are present, but do not form a conspicuous layer. The ground layer is very sparse with much exposed rock on the surface. Occurs on crest and slopes of dissected Tertiary sandstone tablelands. Soils shallow, stony, lithosols and gravelly red earths, with exposed calcareous sandstone and occasionally silcrete duricrust. Not a Wetland. (BVG1M: 24a).

Vegetation communities in this regional ecosystem include:
5.7.14x1: A variety of shrub species occur together to form a open shrubland. Senna artemisioides subsp. oligophylla, Acacia sibirica, Eremophila freelingii, Acacia calcicola usually dominate the shrub layer with scattered Corymbia terminalis and Atalaya hemiglauca trees frequently present. The ground layer is very sparse with exposed rock common. Treeless and shrubless areas are common. Occurs on crest and slopes of dissected Tertiary sandstone tablelands. Soils shallow, stony, lithosols and gravelly red earths, with exposed calcareous sandstone and occasionally silcrete duricrust. Not a Wetland. (BVG1M: 24a).

Protected areas Diamantina NP
Fire management guidelines SEASON: Various (wet season or winter). INTENSITY: Low - 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 (e.g., A. shirleyi, A. aneura) and may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems.
Comments 5.7.14: Toko Range. 5.7.14x1: Moses sandstone, Hamilton Range Diamantina National Park.
