Short description Corymbia terminalis low open woodland on levees of minor streams in limestone country
Structure code Low Open Woodland
Description Corymbia terminalis low open woodland often with Lysiphyllum cunninghamii and/or Eucalyptus leucophylla and/or Eucalyptus camaldulensis. A second tree layer of Terminalia aridicola and/or Hakea arborescens is usually present with a mixed shrub layer including Acacia spp., Carissa lanceolata, Grewia savannicola, Senna spp. And Dodonaea spp. And mixed ground layer of tussock grasses and Triodia pungens. Occurs on recent levees of smaller streams in limestone landscapes. Riverine. (BVG1M: 19b).
Protected areas Boodjamulla (Lawn Hill) NP, Lawn Hill (Gregory) RR
Fire management guidelines SEASON: Storm season to very early dry season. INTENSITY: Low with occasional moderate. INTERVAL: 4 - 10 years. Ensure some areas are long (10-20 years) unburnt. Adjust intervals/frequency according to rainfall-drought cycles, fuel accumulation and previous fire history. INTERVAL_MIN: 4. INTERVAL_MAX: 20. STRATEGY: Ensure burns are undertaken across the landscape at a range of frequencies to create a mosaic of times since fire. Apply numerous small burns every year to achieve a mosaic and reduce risks of wildfire across vast areas of the landscape. Maintain burnt areas < 20%. ISSUES: Rainfall is a major factor affecting spinifex growth, such that a very wet year or a series of wet years may boost the spinifex fuel load leading to the possibility of extensive wildfire in subsequent years. Buffel grass can promote high intensity fire. Fuel loads tend to be higher where there is a mix of tussock and spinifex grasses.
Comments 1.3.14: This vegetation community was previously mapped as 1.3.6x2.
