| Regional ecosystem | 11.11.17 |
|---|---|
| Vegetation Management Act class | Endangered |
| Wetlands | Not a Wetland |
| Biodiversity status | Endangered |
| Subregion | 13, 3, (15), (7) |
| Estimated extent1 | Pre-clearing 2000 ha; Remnant 2021 600 ha |
| Short description | Dichanthium sericeum tussock grassland on old sedimentary rocks with varying degrees of metamorphism and folding |
| Structure code | Tussock Grassland |
| Description | Dichanthium sericeum tussock grassland with Eucalyptus melanophloia and E. orgadophila scattered trees or low open woodland on rises. Occurs on gently undulating plains and rises formed on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Not a Wetland. (BVG1M: 30b). |
| Fire management guidelines | SEASON: Late wet to early dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Various. Mainly low, but also moderate. INTERVAL: >5 years. INTERVAL_MIN: 5. INTERVAL_MAX: 50. STRATEGY: Low to moderate burns can help limit the spread of fires. Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. ISSUES: Fire can be used to control weed invasions, although there are also risks of promoting weeds. |
| Comments | 11.11.17: Modified by total grazing pressure and invasion by buffel grass. |
