| Short description | Corymbia stockeri +/- Eucalyptus crebra low open forest on granite ranges and headlands |
| Structure code | Low Open Forest |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.12.39a. Corymbia stockeri and Eucalyptus crebra (narrow-leaved ironbark) 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. Occurs Melville Range and headlands. Not a Wetland. (BVG1M: 13a). |

| Comments | 3.12.24: 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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
