Regional ecosystem 11.8.15
Vegetation Management Act class Endangered
Wetlands Not a Wetland
Biodiversity status Endangered
Subregion 31, 10, 15, (6), (22)
Estimated extent1 Pre-clearing 12000 ha; Remnant 2021 1000 ha
Short description Eucalyptus brownii or Eucalyptus populnea woodland on Cainozoic igneous rocks
Structure code Woodland
Description Eucalyptus brownii (subregion 2) or E. populnea (subregion 31) grassy woodland to open woodland. A dense shrubby layer may be present. Occurs on flat to gently undulating plains to low hills, formed from Cainozoic igneous rocks. Reddish brown to brown clay or clay loam soils. Not a Wetland. (BVG1M: 17a).
Supplementary description Christian et al. (1953), Strathmore; Harris et al. (1998), 7b
Special values 11.8.15: Potential habitat for NCA listed species: Homopholis belsonii.
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: Low to moderate. INTERVAL: 6-10 years (shorter intervals in north of bioregion: 3 - 7 years). INTERVAL_MIN: 3. INTERVAL_MAX: 10. STRATEGY: Restrict to less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. Sometimes a small amount of wind may move the fire front quickly so that burn intensity is not too severe to destroy habitat trees. ISSUES: Burn interval for conservation purposes will differ from that for grazing purposes; the latter being much shorter. Management of this vegetation type should be based on maintaining vegetation composition, structural diversity, fauna habitats (in particular hollow-bearing trees and logs) and preventing extensive wildfire. Maintaining a fire mosaic will help ensure protection of habitat and mitigate against wildfires. Fire can control shrub invasives (e.g., Eremophila spp. and A. stenophylla in the red soil country in particular). Fire will also control cypress. Low to moderate intensity burns with good soil moisture are necessary to minimise loss of hollow trees. Avoid burning riparian communities as these can be critical habitat for some species. Planned burns have traditionally been carried out in the winter dry season; further research required.
