|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 4, 2, (6), (5) |
| Estimated extent1 | Pre-clearing 54000 ha; Remnant 2021 53000 ha |
| Short description | Eucalyptus persistens +/- E. crebra woodland on flats on Tertiary remnant plains |
| Structure code | Woodland |
| Description | Woodland to open woodland of Eucalyptus persistens (box) +/- E. crebra (narrow-leaved ironbark) +/- Corymbia dallachiana (Dallachy's gum). E. brownii (Reid River box) can sometimes occur as a dominant. A sparse to mid-dense shrub layer can include Petalostigma banksii (smooth-leaved quinine), Denhamia cunninghamii (yellowberry bush), Atalaya hemiglauca (whitewood), Carissa lanceolata (currantbush) and Eremophila mitchellii (false sandalwood). A dense grassy cover can include Bothriochloa decipiens, Chrysopogon fallax (golden beard grass) and Heteropogon spp. Occurs on level and undulating Tertiary remnant plains. Not a Wetland. (BVG1M: 19d). |
| Protected areas | Girringun NP, Girringun CP, Forty Mile Scrub NP |
| 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 | 9.5.11: Occurs extensively in the south central southern part of the bioregion. |
