Short description Eucalyptus crebra, E. exserta, Melaleuca spp. woodland on alluvial plains
Structure code Woodland
Description Eucalyptus crebra, E. exserta, Corymbia dallachiana, C. intermedia woodland usually with a low tree understorey of Melaleuca viridiflora and M. nervosa. Occurs on broad plains and fans formed from Quaternary alluvium. Usually associated with bleached sodic duplex soils. Not a Wetland. (BVG1M: 18b).

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: Various. INTERVAL: Most intervals between 5-10 years, with no shrubby woodlands receiving two consecutive intervals of < 6 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Once boundaries of the planned burning area are secure, ignite across the landscape in a patchwork, rather than continuous ignition strips. Use topographical features to help create a patchily burnt landscape. Where shrubby woodlands occur within a broader grassy landscape, attempt to burn the shrubby woodland during every second fire rotation in the grassy woodland, by burning early breaks around the shrubby areas. In sites with a history of wildfires recurring within 5 years, patchy burning in a few small strategic locations at 3 or 4 year intervals may reduce the incidence of extensive wildfires, while ensuring most shrubby woodland areas remain unburnt for > 5 years. ISSUES: Shrubby woodlands require longer fire intervals than grassy woodlands, because of the presence of fire-killed shrubs and the time required for post-fire regrowth to return to a mature structure. The seedlings of many fire-killed shrubs (such as some wattles) require 5 years or more before they mature. The creation of a fine-scale patchy mosaic can be more difficult to achieve in shrubby compared to grassy woodlands. Ensure seedlings of fire-killed shrubs mature and persist in the woodland. A mature shrubby woodland structure should be allowed to develop before a subsequent fire.
Comments 11.3.29: Occurs also in drier coastal parts of Central Queensland Coast bioregion.
