Biodiversity status No concern at present
Subregion 4, (7.5)
Estimated extent1 Pre-clearing 29000 ha; Remnant 2021 29000 ha
Short description Corymbia leichhardtii, C. lamprophylla, Pleiogynium timorense +/- Araucaria cunninghamii open woodland on igneous hills
Structure code Open Woodland
Description Open woodland of Corymbia leichhardtii (yellowjacket), Araucaria cunninghamii (Hoop pine), C. lamprophylla, Pleiogynium timorense (Burdekin plum), Cochlospermum gillivraei and Lophostemon grandiflorus (Northern swamp box). A. cunninghamii often occurs as an emergent. The mid layer varies from scattered individuals to a mid-dense shrub layer and can include Acacia leptostachya (slender wattle). The ground layer is usually dominated by Triodia spp. (spinifex). Occurs on steep granite or rhyolite hills. Not a Wetland. (BVG1M: 13a).
Special values 9.12.35: Potential habitat for NCA listed species: Corchorus subargenteus, Marsdenia brevifolia.
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. Avoid burning August-October when south-easterly winds are typically strongest. INTENSITY: Low, with occasional moderate or high. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Apply mosaic across the landscape at a range of frequencies to create varying stages of post-fire response. ISSUES: These ecosystems contain shrubs that germinate after fire. Seedlings typically take a number of years to mature. Avoid repeated fires at short intervals and high intensity burns of broad areas. Leave areas of long unburnt vegetation to maintain a diversity of habitat for wildlife. Shrub species diversity will decline if areas are left long unburnt.
Comments 9.12.35: Occurs south west of Hidden Valley in the south east of the bioregion.
