Regional ecosystem details for 6.7.13

Regional ecosystem 6.7.13
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status No concern at present
Subregion 8, 10, (6), (4), (11), (3), (4.4), (5)
Estimated extent1 Pre-clearing 409000 ha; Remnant 2021 377000 ha
Short description Acacia catenulata +/- A. petraea tall shrubland on scarps and tops of ranges
Structure code Tall Shrubland
Description Acacia catenulata tall shrubland to low open forest, occasionally with A. petraea, Acacia aneura and A. ensifolia. Emergent Eucalyptus melanophloia, E. thozetiana, Corymbia terminalis and E. exserta trees may occur. A low shrub layer my occur, including Dodonaea sinuolata subsp. acrodentata and Eremophila latrobei. Acacia clivicola. The ground layer is dominated by grasses such as Aristida caput-medusae, Paspalidium rarum and Urochloa foliosa. Occurs on the tops and scarps of dissected lateritic tablelands, mesas and buttes formed from chemically altered cretaceous sediments. Associated soils are yellowish-brown to red, acid, loamy, lithosols with surface stone cover of silcrete and ferricrete. Weathered base rock is often exposed. Not a Wetland. (BVG1M: 24a).
Supplementary description Dawson (1974), R5 (LU 91); R6 (91); Neldner (1984), 49 (75, 77, 100); Mills and Lee (1990), R2 (LU 58)
Protected areas Currawinya NP, Mariala NP
Special values 6.7.13: Habitat for fauna of conservation significance, yellow-footed rock wallaby (Petrogale xanthopus celeris).
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.
Comments 6.7.13: Larger areas (> 5ha) dominated by Acacia petraea are included under regional ecosystem 6.7.7a.
