| Structure code | Woodland |
| Description | Woodland of Corymbia hylandii (Hylands bloodwood), usually with Eucalyptus tetrodonta (Darwin stringybark). Occasional species include E. cullenii (Cullen's ironbark ironbark) and E. platyphylla (poplar gum). A sparse sub-canopy of canopy species +/- Melaleuca stenostachya (fibre-barked tea-tree) can occur. The shrub layer is very sparse to sparse and usually dominated by canopy species. The sparse grassy groundlayer is usually dominated by Themeda triandra (Kangaroo grass). Occurs on metamorphic hills and headlands. Not a Wetland. (BVG1M: 14d). Vegetation communities in this regional ecosystem include: 3.11.10a: [RE not in use]²: This vegetation community is now mapped as 3.11.11. Corymbia stockeri (gum-topped bloodwood) and Eucalyptus tetrodonta (Darwin stringybark) are the dominant species in the sparse canopy (10-15m tall). Eucalyptus chlorophylla (shiny-leaved box) and E. cullenii (Cullen's ironbark) are frequently present as subdominant trees. The very sparse to sparse shrub layer (0.1-3m tall) is composed of a variety of species that may dominate at different sites, Corymbia stockeri, E. tetrodonta, Melaleuca stenostachya (fibre-barked teatree) and Petalostigma banksii (smooth-leaved quinine) the most frequent dominants. The ground layer is sparse to mid-dense, and dominated by the grasses, Triodia microstachya (spinifex), Eriachne spp. (wanderrie grass), Aristida spp. (three-awned speargrass), Schizachyrium spp. (fire grass), Heteropogon triticeus (giant spear grass) and Digitaria spp. Occurs on metamorphic hills. Not a Wetland. (BVG1M: 14d). 3.11.10b: [RE not in use]²: This vegetation community is now mapped as 3.10.6x4. Corymbia stockeri and Eucalyptus crebra form an even but discontinuous canopy (6-8m tall). E. brassiana (Cape York redgum) is usually present but generally occurs at low densities. Eucalyptus mediocris (mahogany) occurred in the canopy at Cape Bedford. There are two very sparse layers of shrubs and young trees; one 2-4m tall dominated by young Eucalyptus spp. And the other 0.5-1m tall dominated by Acacia calyculata, Dodonaea lanceolata var. subsessilifolia, Erythrophleum chlorostachys (Cooktown ironwood), Jacksonia thesioides and Xanthorrhoea johnsonii (grass-tree). The ground layer is very sparse and dominated by graminoids. Most of the soil surface is covered with leaf litter or exposed rock. RE is defunct. Not a Wetland. (BVG1M: 14d). |
| 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: 2-5 years. INTERVAL_MIN: 2. INTERVAL_MAX: 5. 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 | 3.11.10: Includes areas previously mapped as 3.11.10a. Central Peninsula and south from Cape Melville. 3.11.10a: Central Peninsula. 3.11.10b: Now mapped as 3.10.6x4. The height of the canopy is frequently determined by exposure to prevailing south-easterly winds. In very rocky areas, a dwarf open heath of Allocasuarina littoralis, Grevillea pteridifolia, Hibbertia oblongata and Jacksonia thesioides forms, while in deeper gullies, Eucalyptus brassiana and Acacia leptocarpa become prominent. In sheltered, more mesic positions, particularly gullies, Erythrophleum chlorostachys forms a prominent component of the canopy. Lophostemon suaveolens and Allocasuarina littoralis may also be present in the canopy, and Corymbia tessellaris is sometimes present as an emergent tree (10m tall). A denser shrub layer (2-4m tall, 20% PFC) is frequently present. Buchanania arborescens, Canarium australianum and Schefflera actinophylla occur in some gullies. Occurs on Melville Range and coastal headlands in south of bioregion. |
1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
