| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.3.20. Corymbia clarksoniana (Clarkson's bloodwood) dominates the sparse canopy (13-25m tall). Erythrophleum chlorostachys (Cooktown ironwood) is a frequent subdominant tree. Eucalyptus tetrodonta (Darwin stringybark) is present but at lower stem densities. The sparse sub-canopy (6-15m tall) is dominated by Erythrophleum chlorostachys and Melaleuca nervosa (a paperbark). A number of other species are frequently present. The sparse shrub layer (0.5-3m tall) is composed of a variety of species which includes Alphitonia pomaderroides (soapwood), Erythrophleum chlorostachys and Melaleuca nervosa. The ground layer is mid-dense to dense. Schizachyrium fragile (fire grass), Sarga plumosum (plume sorghum), Heteropogon triticeus (giant speargrass), Themeda arguens and Panicum spp. (native panic) are the dominant grasses. Occurs on levees associated with streams. Not a Wetland. (BVG1M: 9e). |
| 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: 1-3 years. INTERVAL_MIN: 1. INTERVAL_MAX: 3. 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. These communities require particular management attention due to issues of grazing, weed invasion, rapid fuel accumulation, poor access and woody thickening. Fuel can reach maximum accumulation in 2 years. |
| Comments | 3.3.23: South-west of bioregion and in Lakefield NP. Extends into adjacent Gulf Plains 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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
