Regional ecosystem details for 9.12.22
| Regional ecosystem | 9.12.22 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 4, (11.1), (7.5) |
| Estimated extent1 | Pre-clearing 65000 ha; Remnant 2021 65000 ha |
| Short description | Eucalyptus drepanophylla, Corymbia clarksoniana or C. intermedia and C. dallachiana woodland on steep rugged igneous ranges |
| Structure code | Woodland |
| Description | Woodland of Eucalyptus drepanophylla (grey ironbark), Corymbia clarksoniana (Clarkson's bloodwood) or C. intermedia (pink bloodwood), C. dallachiana (Dallachy's gum) +/- E. platyphylla (poplar gum) +/- E. portuensis (white mahogany) +/- E. tereticornis (bluegum). An open to mid-dense sub-canopy can include Planchonia careya (cocky apple), Acacia flavescens (yellow wattle), Bursaria incana (prickly pine), Vachellia bidwillii (corkwood wattle) and Grevillea parallela (silver oak). Capparis canescens (wild orange), Larsenaikia ochreata (native gardenia) and Acacia spp. occur in a scattered shrub layer. The ground layer is dense grassy and dominated by Themeda triandra (kangaroo grass), Heteropogon contortus (black speargrass) and H. triticeus (giant speargrass). C. erythrophloia (red bloodwood) may be found in the western area of this community. Occurs in steep rugged hills and valleys on igneous steep rugged ranges. Not a Wetland. (BVG1M: 13c). |
| Protected areas | Paluma Range NP, Pinnacles NP, Girringun NP |
| Special values | 9.12.22: Potential habitat for NCA listed species: Scleromitrion polycladum. |
| Fire management guidelines | SEASON: Early dry season and storm time. Timing of early dry season burns will vary depending on seasonal conditions; it may sometimes commence as early as March. INTENSITY: Low, with occasional moderate. INTERVAL: 2-5 year intervals with longer unburnt patches. Fuel loads tend to reach a maximum after 2-3 years. Ensure burn programs occur after big wet season as fuel loads will be higher than average. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Burn less than 40% across the landscape in any year. Burning through the early dry season will produce a network of burns that will contain later fires. Fires will only gain in intensity as the dry season progresses. Grass composition can be affected by timing and intensity of fire. Occasional moderate fire will help to reduce overabundant trees that could potentially suppress ground layer vegetation. ISSUES: Leave areas of long unburnt vegetation to maintain a diversity of habitat for wildlife. |
| Comments | 9.12.22: Is distinguished from RE 9.12.21 and RE 9.12.2 by the different mix of dominant species and by a different landform. Occurs adjacent to the Wet Tropics boundary. Subject to clearing and vulnerable to invasion by the weed species Lantana camara. . |
