Estimated extent1 Pre-clearing 5000 ha; Remnant 2017 5000 ha
Extent in reserves Medium
Short description Corymbia tessellaris +/- Welchiodendron longivalve +/- Eucalyptus cullenii open forest on footslopes of granite hills
Structure category Mid-dense
Description Open forest of Corymbia tessellaris (Moreton Bay ash) +/- Welchiodendron longivalve (yellow box penda) +/- E. cullenii (Cullen's ironbark) +/- Corymbia clarksoniana. The very sparse subcanopy may contain a number of vine forest species. A very sparse shrub layer may occur. The often mid-dense grassy ground layer is usually dominated by Heteropogon triticeus (giant spear grass) and / or Imperata cylindrica (blady grass) +/- other grass species. Occurs in footslopes and gullies off granite hills. (BVG1M: 9c)

Protected areas Lizard Island NP, KULLA (McIlwraith Range) NP (CYPAL)
Fire management guidelines SEASON: Commence planned burns early in the dry season, after the wet season when dry enough to burn. Use occasional storm burns but generally avoid periods of extremely hot, dry conditions. INTENSITY: Low to moderate with occasional high during storm burns. INTERVAL: 1-5 years. STRATEGY: Apply a mosaic across the landscape at a range of intervals to create varying stages of post-fire response. Burn 30-60% at the property level. ISSUES: To mitigate against the impact of late dry season fires, commence burning early in the season and continue through the dry to break up continuity of fuels across the landscape. Planned fire applied repeatedly early in the dry season may lead to woody thickening because fires are not of sufficiently high intensity; this may be exacerbated by stock grazing. Manage extent, intensity and frequency of fires judiciously, to avoid habitat tree loss.
Comments There are several variants of this RE which include an open forest of Corymbia tessellaris, Acacia crassicarpa and Lophostemon suaveolens (Lizard Island), a windswept shrubland of C. tessellaris and Jacksonia thesioides (Horn Island) and an open forest of C. tessellaris and Eucalyptus brassiana. Where frequent burning has occurred on some Torres Strait islands the communities are more open and grassy with emergent shrubs including Grevillea parallela (silver oak), Pandanus sp. and Livistona muelleri or as an open woodland with a mid layer that can include Livistona muelleri, A.leptocarpa and Melaleuca nervosa (woodland paperbark). East of McIlwraith Range and inner Torres Strait islands.
