Subregion 1, (9.4)
Estimated extent1 Pre-clearing 5000 ha; Remnant 2021 4000 ha
Short description Acacia leptostachya shrubland on Cainozoic sand plains and/or remnant surfaces
Structure code Shrubland
Description Acacia leptostachya shrubland. Occurs on Cainozoic sandplains. Not a Wetland. (BVG1M: 24a).
Supplementary description Gunn et al. (1967), Lennox, Tichbourne
Fire management guidelines SEASON: Various. INTENSITY: Moderate to high. INTERVAL: 8-15 years. INTERVAL_MIN: 8. INTERVAL_MAX: 15. STRATEGY: Burn in association with surrounding vegetation. Burn less than 30% in any year. ISSUES: Acacia leptostachya, and others, has germination promoted by fires, but seedlings require > 5 years to mature. These Acacias begin to senesce after approximately 10 to 15 years, and associated grasses disappear after around 5 to 10 years. Therefore burning intervals of 8 to 15 years can maintain the species composition and structure of this community. Ensure mature woodland structure persists for many years in between fire events; maintain a diverse grass layer in sections of this ecosystem.

1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
