Short description Acacia georginae tall open shrubland +/- Senna artemisioides subsp. oligophylla +/- Eremophila freelingii on minor drainage lines and alluvial plains
Structure code Tall Shrubland
Description Acacia georginae tall open shrubland with an open shrub layer of Senna artemisioides subsp. oligophylla and Eremophila freelingii frequently present. The ground layer varies from very sparse to open, and is usually dominated by perennial grasses. Eragrostis setifolia and Enneapogon avenaceus usually dominate on texture contrast soils and non-cracking red clays and Bothriochloa ewartiana, Eulalia aurea, Eragrostis setifolia and Astrebla pectinata usually dominate on alluvia and on red and brown cracking clays. A variety of forbs occur infrequently, but may be seasonally co-dominant. Occurs along on minor drainage lines and alluvial plains. Soils vary from deep, red and brown cracking clays to alluvial texture contrast soils and non-cracking clays. Not a Wetland. (BVG1M: 26a).

Protected areas Munga-Thirri 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 when fire is more easily controlled. ISSUES: Rarely burns due to low fuel loads.
Comments 5.3.11: Georgina River area. In many areas 30-50% of tall shrubs stand dead, although regeneration of Acacia georginae present in some areas (Neldner, 1991).
