Regional ecosystem details for 10.3.19
| Regional ecosystem | 10.3.19 |
|---|---|
| Vegetation Management Act class | Endangered |
| Wetlands | Not a Wetland |
| Biodiversity status | Endangered |
| Subregion | 2 |
| Estimated extent1 | Pre-clearing 5000 ha; Remnant 2021 1000 ha |
| Short description | Acacia cambagei woodland on lakeside dunes |
| Structure code | Woodland |
| Description | Acacia cambagei open forest, commonly with a second tree layer of Eremophila mitchellii. Shrub layer of Eremophila mitchellii and Carissa lanceolata and sparse mixed ground layer. Occurs on calcareous duplex soils on old dunes and degraded dune material fringing Lake Galilee. Not a Wetland. (BVG1M: 26a). |
| Supplementary description | Gunn et al. (1967), G; Lorimer (1998), Qd2; Thompson and Turpin (in prep), A13f |
| Special values | 10.3.19: This ecosystem is an unusual occurrence, having significant geomorphic values indicative of past climates. It is endemic to Lake Galilee. |
| Fire management guidelines | SEASON: Wet to mid-dry season. Avoid late dry (August -September) as intensity will be too high (August -September). INTENSITY: Low. INTERVAL: 6-10 years, but will depend on seasonal conditions and grazing pressure. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Fire is not generally applied directly to acacia dominated communities, but to surrounding fire-adapted communities in order to create a landscape mosaic of burnt/unburnt areas to mitigate against wildfire. Ensure fires are patchy. ISSUES: Acacias are fire sensitive and may be killed by high intensity or too frequent fire. These communities generally have sparse ground layer. Will only burn following irregular high rainfall events. Buffel may lead to high fire intensities where ecosystem is heavily infested. |
| Comments | 10.3.19: Fringing Lake Galilee. The deep fine sandy topsoils have very low fertility and are extremely susceptible to wind erosion. It is largely cleared for pasture development. Remnants have heavy infested with Buffel grass. |
