Subregion 10, 8, 5.5, 9, (6), (11), (7), (4.4), (5.6)

Short description Acacia cambagei low woodland on braided channels
Structure code Low Woodland
Description Acacia cambagei low woodland to woodland, occasionally with Atalaya hemiglauca and Flindersia maculosa. A shrub layer may be absent but often tall shrubs such as Eremophila mitchellii and Geijera parviflora or low shrubs such as E. glabra, Enchylaena tomentosa and Eremophila deserti are present as scattered individuals. The ground layer is seasonally dominated by a large number of short grass, forb and annual herb species. The dominant short grasses are Chloris pectinata, Sporobolus actinocladus and S. caroli. The dominant forbs include Sclerolaena spp., Abutilon oxycarpum, Sida fibulifera, S. everistiana, Salsola australis, Solanum esuriale and Trianthema triquetra. Occurs on the fringes of braided channels. Soils are very deep, reddish-brown to brown, cracking clays or texture contrast soils with sandy surfaces. Riverine. (BVG1M: 26a).

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 6.3.6: Some clearing is occurring. Scalding is common around margins (Mills and Lee, 1990, 219).Naturalised species associated with this regional ecosystem include *Malvastrum americanum and *Portulaca oleracea.
