| Structure code | Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.7.4. Corymbia stockeri subsp. peninsularis (gum-topped bloodwood) and Eucalyptus tetrodonta usually dominate the sparse canopy (9-15m, occasionally 20m tall). Melaleuca stenostachya (fibre-barked teatree) usually dominates a very sparse sub-canopy tree layer (8-12m tall). M. viridiflora (broad-leaved teatree) is also frequently present. A sparse shrub layer (3-8m tall) is usually present. Petalostigma banksii (smooth-leaved quinine) and C. stockeri frequently dominate this layer. The ground layer is sparse to mid-dense and dominated by the grasses, Schizachyrium fragile (fire grass), Sarga plumosum (plume sorghum) and Heteropogon triticeus (giant speargrass). Occurs on ironstone knolls and erosional surfaces. Not a Wetland. (BVG1M: 14b). Vegetation communities in this regional ecosystem include: 3.7.5a: [RE not in use]²: This vegetation community is now mapped as 3.7.4. Corymbia stockeri subsp. peninsularis (gum-topped bloodwood) and Eucalyptus tetrodonta (Darwin stringybark) usually dominate the sparse canopy (9-15m, occasionally 20m tall). Melaleuca stenostachya (fibre-barked teatree) usually dominates a very sparse sub-canopy tree layer (8-12m tall). M. viridiflora (broad-leaved teatree) is also frequently present. A sparse shrub layer (3-8m tall) is usually present. Petalostigma banksii (smooth-leaved quinine) and C. stockeri frequently dominate this layer. The ground layer is sparse to mid-dense and dominated by the grasses, Schizachyrium fragile (fire grass), Sarga plumosum (plume sorghum) and Heteropogon triticeus (giant speargrass). Occurs on ironstone knolls and erosional surfaces. Not a Wetland. (BVG1M: 14b). 3.7.5b: [RE not in use]²: This vegetation community is now mapped as 3.5.38b. Eucalyptus tetrodonta (Darwin stringybark) +/- Corymbia stockeri subsp. peninsularis (gum-topped bloodwood) co dominate the sparse canopy. C. nesophila (Melville Island bloodwood) is present at most sites as a subdominant canopy tree. The very sparse to sparse sub-canopy layer is dominated by the same Eucalyptus spp. and Corymbia spp. which are found in the canopy and by Acacia rothii (Roth's wattle), Grevillea glauca (bushman's clothes peg), Parinari nonda (nonda) and Erythrophleum chlorostachys (Cooktown ironwood). The shrub layer varies from mid-dense to very sparse and is composed of a variety of species which may vary from site to site. The most commonly encountered species in this layer are Eucalyptus spp. and Corymbia spp. that also occur in the tree layer and Planchonia careya. The ground layer is sparse to mid-dense and dominated by the grasses Heteropogon triticeus (giant speargrass), Aristida spp. (three-awned speargrass), Schizachyrium spp. (fire grass) and Sarga plumosum (plume sorghum). Occurs on lateritised plateaus & slopes. Not a Wetland. (BVG1M: 14b). |
| Special values | 3.7.5: Habitat for the near threatened species Acacia ommatosperma. |
| 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 | 3.7.5: Restricted to south central Peninsula west of Musgrave. 3.7.5b: Cape Weymouth. |
1 Estimated extent is from version 13 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.
