Regional ecosystem details for 9.5.12
| Regional ecosystem | 9.5.12 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 3 |
| Estimated extent1 | Pre-clearing 30000 ha; Remnant 2021 27000 ha |
| Short description | Eucalyptus chlorophylla and/or E. tardecidens woodland on Tertiary plains |
| Structure code | Woodland |
| Description | Woodland to open woodland of Eucalyptus chlorophylla (box) and/or E. tardecidens (box) +/- E. cullenii (Cullen's ironbark) +/- Melaleuca stenostachya +/- Terminalia spp. There is sometimes an open sub-canopy layer which can include Melaleuca spp., Terminalia platyptera (yellow-wood) and Grevillea striata (beefwood). The very sparse shrub layer can contain Dolichandrone alternifolia (lemonwood), Melaleuca spp., Terminalia spp., and Petalostigma pubescens (quinine). The sparse to mid-dense ground layer can include Heteropogon contortus (black speargrass), Sarga plumosum (plume sorghum), Schizachyrium fragile (firegrass), Themeda spp. and Aristida spp. Occurs on undulating plains on Tertiary remnants. Not a Wetland. (BVG1M: 18c). |
| Protected areas | Mount Windsor NP |
| Special values | 9.5.12: Potential habitat for NCA listed species: Habenaria rumphii. |
| 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 | 9.5.12: Occurs near Mt Carbine and Lakeland Downs in the north of the bioregion. Some small scale clearing and logging occurring west of Mareeba and south of Mt. Garnet. |
