| Short description | Acacia calcicola +/- A. aneura tall shrubland between sand dunes |
| Structure code | Tall Shrubland |
| Description | Acacia calcicola tall shrubland. Acacia aneura occurs frequently and co-dominates in places. Other scattered low trees or shrubs, such as Acacia excelsa, Acacia ramulosa, Acacia tetragonophylla, Santalum lanceolatum, Senna phyllodinea, Enchylaena tomentosa, Eremophila duttonii and Rhagodia spinescens, may be present. Ground cover is variable and composed of forbs and grasses including Aristida holathera var. holathera, Aristida contorta, Sclerolaena spp., Ipomoea polymorpha, Sida platycalyx, Dactyloctenium radulans, Enteropogon acicularis, Atriplex spongiosa and Maireana spongiocarpa. Occurs on cemented aprons on lower slopes and edges of low (2-3m) sand dunes occurring on flat alluvial plains. Associated soils are shallow to moderately deep (to very deep), red sandy loam to sandy clay loam usually with a ferruginous hard pan and some associated texture contrast soils. Not a Wetland. (BVG1M: 26a). |

| 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: Winter and/or wet/storm season burns can be used. Some Acacia spp. are fire sensitive (e.g., A. aneura, A. georginae, A. cambagei) and may be killed by high intensity fire. |
| Comments | 5.6.3: Lack of Acacia calcicola regeneration due to total grazing pressure. High level of rabbit infestation. |
