| Description | [RE not in use]²: This regional ecosystem is now mapped as part of either 3.3.20 or 3.5.41. Woodland to (occasionally) open forest of Corymbia clarksoniana (Clarkson's bloodwood) +/- Erythrophleum chlorostachys (Cooktown ironwood) and C. dallachiana (Dallachy's gum). Melaleuca nervosa (woodland paperbark) is a consistent sub-canopy tree but a number of other species are often present in this layer. There is also a sparse to very sparse shrub layer. Occurs on undulating rises and plains. Not a Wetland. (BVG1M: 9e). Vegetation communities in this regional ecosystem include: 3.5.22a: [RE not in use]²: This vegetation community is now mapped as 3.5.41. Corymbia clarksoniana (Clarkson's bloodwood) dominates the sparse canopy. Erythrophleum chlorostachys (Cooktown ironwood) is a frequent subdominant tree. Eucalyptus tetrodonta (Darwin stringybark), E. leptophleba (Molloy red box) and E. chlorophylla (shiny-leaved box) are also sometimes present as subdominant trees. The sub-canopy is dominated by Melaleuca viridiflora (broad-leaved teatree) and often includes M. nervosa (woodland paperbark) and Grevillea glauca (bushman's clothes peg). The very sparse to sparse shrub layer is dominated by M. viridiflora, M. nervosa, C. clarksoniana, Acacia leptocarpa (a wattle) and Alphitonia pomaderroides (soapwood). The ground layer is sparse to mid-dense. Sarga plumosum (plume sorghum), Themeda triandra (kangaroo grass), Eriachne triseta (wanderrie grass) and Heteropogon triticeus (giant speargrass) are the primary grasses. Occurs on undulating rises and plains. Not a Wetland. (BVG1M: 9e). 3.5.22b: [RE not in use]²: This vegetation community is not mapped. Corymbia clarksoniana (Clarkson's bloodwood) dominates the sparse to mid-dense canopy. Corymbia dallachiana (Dallachy's gum) and Erythrophleum chlorostachys (Cooktown ironwood) are frequent subdominant trees. Lophostemon suaveolens (swamp mahogany) and Melaleuca dealbata (silver-leaved paperbark) are also sometimes present. M. nervosa (woodland paperbark) is a consistent sub-canopy tree but a number of other species are often present in this layer. The sparse shrub layer is composed of a variety of species particularly E. chlorostachys and Alphitonia pomaderroides (soapwood). The ground layer is sparse to dense and dominated by the grasses Heteropogon triticeus (giant speargrass), H. contortus (black speargrass), Themeda triandra (kangaroo grass) and Panicum spp. (native panic). Occurs on undulating rises and plains. Not a Wetland. (BVG1M: 9e). 3.5.22c: [RE not in use]²: This vegetation community is now mapped as 3.3.20. Corymbia clarksoniana (Clarkson's bloodwood) dominates the sparse canopy. In the northern areas, this species is replaced by another bloodwood, C. novoguinensis. Lophostemon suaveolens (swamp mahogany), Parinari nonda (nonda) and less frequently Erythrophleum chlorostachys (Cooktown ironwood) are subdominant trees. The sparse sub-canopy is most frequently dominated by Melaleuca viridiflora (broad-leaved teatree). Livistona muelleri (dwarf fan palm) and Alphitonia pomaderroides (soapwood) are also common components of this layer. Antidesma ghaesembilla (black currant) and Flueggea virosa subsp. melanthesoides (white currant) are characteristic species of the sparse shrub layer. The ground layer is sparse to dense and dominated by Fimbristylis sp., Heteropogon triticeus (giant speargrass), Aristida sp. (three-awned speargrass) and Ischaemum spp. Occurs on undulating rises and plains. Not a Wetland. (BVG1M: 9e). 3.5.22d: [RE not in use]²: This vegetation community is not mapped. Corymbia clarksoniana (Clarkson's bloodwood) dominates the sparse canopy. C. dallachiana (Dallachy's gum) is usually present as a subdominant canopy tree. Melaleuca nervosa (woodland paperbark) occasionally occurs in the canopy but is more common as a sub-canopy tree. Other common sub-canopy trees are Piliostigma malabaricum (bauhinia), C. clarksoniana and Planchonia careya (cocky apple). Antidesma ghaesembilla (black currant) and C. clarksoniana with Azanza thespesioides consistently forms a sparse shrub layer. The ground layer is sparse and dominated by Ischaemum spp., Eragrostis spp. (love grass), Arundinella setosa (reed grass) and Fimbristylis spp. Occurs on undulating rises and plains. Not a Wetland. (BVG1M: 9e). 3.5.22x1: [RE not in use]²: This proposed new RE is now mapped as 3.5.41. Corymbia clarksoniana (Clarkson's bloodwood) dominates the sparse canopy. Erythrophleum chlorostachys (Cooktown ironwood) is a frequent subdominant tree. Eucalyptus tetrodonta (Darwin stringybark) is present but at lower stem densities. The sparse sub-canopy is dominated by Erythrophleum chlorostachys and Melaleuca nervosa (woodland paperbark). A number of other species are frequently present. The sparse shrub layer is composed of a variety of species which includes Alphitonia pomaderroides (soapwood), Erythrophleum chlorostachys, Indigofera pratensis (forest indigo) and M. 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 alluvial plains. Not a Wetland. (BVG1M: 9e). 3.5.22x2: [RE not in use]²: This proposed new RE is now mapped as 3.5.41. Corymbia clarksoniana (Clarkson's bloodwood) dominates the canopy layer which can vary greatly in height and foliage projective cover. Other Eucalyptus spp. may sometimes be present in the canopy. A very sparse, sub-canopy tree layer dominated by Melaleuca viridiflora (broad-leaved teatree) is usually present. Scattered low shrubs are often present but do not form a conspicuous layer. The ground layer is very sparse to mid-dense and dominated by the grasses Schizachyrium spp. (fire grass), Heteropogon triticeus (giant speargrass), Sarga plumosum (plume sorghum), Eriachne spp. (wanderrie grass) and Pseudopogonatherum spp. Occurs on erosional plains. Not a Wetland. (BVG1M: 9e). |

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.
