| Regional ecosystem | 11.8.12 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Subregion | 10 |
| Estimated extent1 | Pre-clearing 60 ha; Remnant 2021 60 ha |
| Short description | Eucalyptus microcarpa, E. exserta woodland on Cainozoic igneous rocks |
| Structure code | Woodland |
| Description | Eucalyptus microcarpa and E. exserta low forest. Occurs on Cainozoic igneous rocks (trachyte). Not a Wetland. (BVG1M: 13d). |
| Supplementary description | Fensham and Holman (1998a) |
| Protected areas | Peak Range NP |
| Special values | 11.8.12: Never grazed by cattle, due to the inaccessibility of the landform. The population of Eucalyptus microcarpa is isolated from the main occurrence of this species in southern Queensland. |
| Fire management guidelines | SEASON: Early dry season when there is good soil moisture, with some later fires in the early storm season or after good spring rains. INTENSITY: Primarily low to moderate, with occasional high intensity fires. INTERVAL: Typically 2 - 7 years, with some areas longer unburnt. INTERVAL_MIN: 2. INTERVAL_MAX: 7. STRATEGY: A predominance of early dry season fires is recommended, although there is value in occasional late dry season fires, or storm burns, over small areas. Burning should begin very soon after the wet season, to secure boundaries and adjacent fire-sensitive vegetation. Subsequent repeat ignitions can be used within the same section of land weeks or months after the boundaries have been secured by early burning, to produce a mixture of burnt areas with multiple ignition dates. Use topographical features to ignite areas as soon as they dry out. This will create a mosaic of areas that were burnt at different dates and unburnt sections within the same area of woodland. Burn away from riparian communities, which can be critical habitat for some species. Approximately 25% of the grassy woodlands within a landscape should receive patchy fires in most years. ISSUES: Maintaining a fire mosaic will help ensure protection of habitat and mitigate against wildfires. Low to moderate intensity burns with good soil moisture minimise the risk of losing hollow trees. An occasional late season burn will promote grasses and legumes. |
| Comments | 11.8.12: This type is restricted to the plateau surface of Lord's Table Mountain, which is a Tertiary basalt mesa that has been protected from weathering because of its resistant trachytic lava cap (Galloway 1967). |
