Regional ecosystem details for 10.3.20
| Regional ecosystem | 10.3.20 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Extent in reserves | This vegetation community is now mapped as 10.3.28a. |
| Short description | Eucalyptus melanophloia open woodland on older lake-fringing dunes |
| Structure code | Woodland |
| Description | [RE not in use]²: This vegetation community is now mapped as 10.3.28a. Eucalyptus melanophloia dominates the very sparse canopy. Eucalyptus brownii is occasionally present in the canopy. Acacia sericophylla and Grevillea parallela are usually present in a very sparse small tree layer. Acacia melleodora dominates the very sparse shrub layer. Aristida ingrata dominates the very spare ground layer. Occurs on older lake-fringing sand dunes. Not a Wetland. (BVG1M: 17b). |

| Special values | 10.3.20: This ecosystem represents the highest shoreline of ancestral lake systems and is extremely restricted being associated with Lake Galilee and Cauckingburra Swamp. |
| Fire management guidelines | SEASON: Wet to mid-dry season while soil retains moisture. INTENSITY: Low to occasional moderate. INTERVAL: Interval will depend on need for burning, seasonal conditions and grazing pressure. Approximately 5-10 years. Do not burn during drought years. Concentrate burning during wet years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Due to the typically sparse nature of the spinifex in these ecosystems, there is rarely enough fuel load to burn. Patchy burns are preferred. Mosaic 50-80% of area targeted. Burn under conditions of good soil moisture and when plants are actively growing. Burns during dry periods may leave areas of soil exposed, leading to erosion. ISSUES: Spinifex responds to low intensity burning following the first summer rains. De-stock burnt spinifex areas for many months in good seasons or several growing seasons in a run of dry years. |
| Comments | 10.3.20: Extremely restricted ecosystem associated with Lake Galilee and Cauckingburra Swamp. The deep sandy topsoil's have very low fertility, are highly prone to drying out and are prone to wind erosion. These factors greatly limit the duration, quality and quantity of native annual pasture. |
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.
