| Short description | Eucalyptus tetrodonta +/- Corymbia stockeri woodland to tall open forest on erosional plains and remnant plateaus |
| Structure code | Woodland |
| Description | Woodland to tall woodland of Eucalyptus tetrodonta (Darwin stringybark) and Corymbia stockeri (gum topped bloodwood) +/- Erythrophleum chlorostachys (Cooktown ironwood). Occurs on erosional plains and deep massive sands. Not a Wetland. (BVG1M: 14b). Vegetation communities in this regional ecosystem include: 3.5.37a: Woodland of Eucalyptus tetrodonta (Darwin stringybark) and Corymbia stockeri (gum topped bloodwood) +/- Erythrophleum chlorostachys (Cooktown ironwood) +/- C. clarksoniana (Clarkson's bloodwood). The sparse to open subcanopy often contains canopy species +/- Grevillea glauca (clothespeg Grevillea) +/- Melaleuca spp. The sparse to mid-dense shrub layer is predominantly canopy species regrowth +/- Acacia rothii +/- Alphitonia pomaderroides (soapbush) +/- Planchonia careya (cocky apple). The usually dense mixed grassy groundlayer can include Heteropogon triticeus (giant spear grass), Aristida spp. (three-awned speargrass), Sarga plumosum (plume sorghum), Eriachne spp. (wanderrie grasses) and Schizachyrium spp. Occurs on erosional plains. Not a Wetland. (BVG1M: 14b). 3.5.37b: Tall woodland to woodland of Eucalyptus tetrodonta (Darwin stringybark) +/- Corymbia stockeri (gum topped bloodwood) +/- Erythrophleum chlorostachys (Cooktown ironwood) +/- C. clarksoniana (Clarkson's bloodwood). Erythrophleum chlorostachys is most prominent in the sub canopy +/- other canopy species +/- Grevillea glauca (clothespeg Grevillea). Canopy species regrowth is conspicuous in the shrublayer along with Alphitonia pomaderroides (soapbush), Coelospermum reticulatum (medicine bush) and Grevillea parallela. The mid-dense to dense grassy ground layer is dominated by Schizachyrium spp. (fire grass), Heteropogon triticeus (giant spear grass), Alloteropsis semialata (cockatoo grass), and Thaumastochloa spp. Occurs on deep massive soils mainly on the Kimba Plateau. Occurs on deep massive soils mainly on tertiary remnant plateaus, predominantly the Kimba Plateau. Not a Wetland. (BVG1M: 14a). |

| Special values | 3.5.37: Potential habitat for NCA listed species: Jedda multicaulis, Samadera sp. (Kennedy River J.R.Clarkson 5645), Stemona angusta. 3.5.37b: Habitat for the vulnerable plant species Jedda multicaulis. |
| 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 | 3.5.37: REs 3.5.1, 3.5.10 (part) and vegetation communities 3.5.7a, 3.5.8a, 3.5.9a, 3.5.9d (part) were amalgamated in to this RE. C.stockeri is likely to be subsp. peninsularis. Occurs from the Kimba Plateau, throughout the Holroyd Plain and north of Coen. 3.5.37a: Occurs predominantly on erosional plains and rises but can occur on edges of bauxite plateaus. C.stockeri is likely to be subsp. peninsularis. Occurs from the Kimba Plateau, throughout the Holroyd Plain and north of Coen. 3.5.37b: This was previously mapped as 3.5.1. Typical vegetation is on the Kimba Plateau in an area known as the Desert. C.stockeri is likely to be subsp. Peninsularis. 3.5.37b occurs on tertiary remnant plateaus whilst 3.5.37a does not. 3.5.37b is generally taller (above 22m) than 3.5.37a. Predominantly on the Kimba Plateau, but may occur on other tertiary remnant plateaus in small patches below the scale of mapping. |
