| Regional ecosystem | 5.7.7 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Extent in reserves | This regional ecosystem is now mapped as 5.9.2x1. |
| Short description | Acacia cambagei low open woodland with Eragrostis xerophila, Sporobolus actinocladus on sediments on undulating plains |
| Structure code | Low Open Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 5.9.2x1. Acacia cambagei predominates and forms a distinct but discontinuous canopy. Other trees and shrubs are very sparse, except for young Acacia cambagei, which is dense in most areas. The ground layer is open and variable, with Eragrostis xerophila and Sporobolus actinocladus frequently dominant. In many areas, 80-90% of low trees stand dead, but dense Acacia cambagei regeneration usually present. Occurs predominantly on flat to gently undulating plains. Soils shallow to moderately deep, stony red clays or desert loams, with surface ironstone or silcrete gravel. 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: Some Acacias can be fire sensitive (e.g., A. shirleyi, A. aneura) and may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems. |
1 Estimated extent is from version 13 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.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
