Short description Melaleuca viridiflora +/- Neofabricia myrtifolia +/- Petalostigma pubescens on low woodland on granitic ranges
Structure code Low Woodland
Description [RE not in use]²: This regional ecosystem is now mapped as either 3.12.45 or 3.12.47. Woodland to low open woodland of Melaleuca viridiflora (broad-leaved paperbark) +/- Neofabricia myrtifolia (yellow teatree) +/- Asteromyrtus spp. Emergent Corymbia clarksoniana (Clarkson's bloodwood) or Corymbia nesophila (Melville Island bloodwood) may also occur. A sparse sub-canopy layer may be present as is a very sparse to sparse shrub layer. Occurs on granite hills and ranges. Not a Wetland. (BVG1M: 28c).

Vegetation communities in this regional ecosystem include:
3.12.26a: [RE not in use]²: This vegetation community is now mapped as 3.12.47. Melaleuca viridiflora, (broad-leaved teatree) together with Neofabricia myrtifolia (yellow teatree), Allocasuarina littoralis (black sheoak), Asteromyrtus brassii and sometimes Acacia brassii (Brass's wattle) dominate the sparse canopy (4-12m tall). Corymbia nesophila (Melville Island bloodwood) and less frequently Eucalyptus tetrodonta (Darwin stringybark) are present as emergent trees (9-16m tall). The same species dominate the sparse low tree layer (2-5m tall). A sparse shrub layer (0.5-3m tall) is present, with Acacia calyculata, Persoonia falcata (geebung), Hibbertia banksii forma banksii, Melaleuca viridiflora, Asteromyrtus lysicephala (back to front bush) and Choriceras tricorne (Cape Choriceras) occurring at the highest densities. The ground layer is sparse, and frequently dominated by Xanthorrhoea johnsonii (grass tree). Commonly encountered graminoids include Eriachne spp. (wanderrie grasses), Schoenus sparteus and Cleistochloa spp. Occurs on granite ranges. Not a Wetland. (BVG1M: 28c).
3.12.26b: [RE not in use]²: This vegetation community is now mapped as 3.12.45. Melaleuca viridiflora (broad-leaved teatree) dominates the sparse canopy (5-11m tall). Emergent trees of Corymbia clarksoniana (Clarkson's bloodwood) (7-23m tall) are sometimes present. Scattered low trees (2-5m tall) such as Acacia spp. (wattles), Asteromyrtus symphyocarpa (liniment tree) and Banksia dentata (tropical banksia) may be present and a very sparse layer of shrubs (0.3-2m tall) may sometimes be present. The ground layer is sparse to dense and dominated by graminoids. Schizachyrium spp. (fire grass), Scleria spp. (milk drop sedge), Fimbristylis spp., Eremochloa bimaculata (poverty grass), Aristida dominii (three-awned speargrass) and Schoenus sparteus are some of the frequent species in this layer. Occurs on granite ranges. Not a Wetland. (BVG1M: 28c).
3.12.26c: [RE not in use]²: This vegetation community is now mapped as 3.12.45. Melaleuca viridiflora (broad-leaved teatree) dominates a very sparse canopy (4-14m tall) with scattered emergent Corymbia clarksoniana (Clarkson's bloodwood) (8-18m tall) often present. Other Corymbia spp. or Eucalyptus spp. occur very occasionally as emergent trees. A very sparse sub-canopy tree layer (2-9m tall) is present at most sites with Melaleuca viridiflora and Petalostigma pubescens (quinine) occurring at the greatest densities. A very sparse shrub layer (<0.5 m) dominated by M. viridiflora juveniles is present at most sites. The ground layer is sparse to mid-dense and dominated by grasses or sedges in wetter parts. Schizachyrium spp. (fire grass), Aristida spp. (three-awned spear grasses), Eriachne spp. (wanderrie grasses) and Eremochloa bimaculata (poverty grass) are common dominant species in this layer. Occurs on slopes of granite hills. Not a Wetland. (BVG1M: 28c).
3.12.26x1: [RE not in use]²: This proposed new regional ecosystem is now mapped as 3.12.47. Asteromyrtus lysicephala (back to front bush) and Choriceras tricorne dominate the sparse canopy (0.5-1.5m tall). Jacksonia thesioides and Melaleuca viridiflora (broad-leaved paperbark) are subdominant shrubs. Widely scattered M. viridiflora and Grevillea spp. emergent trees (4-6m tall) are sometimes present. The ground layer is very sparse with Schoenus sparteus the most frequent herb. Occurs on granite hills. Not a Wetland. (BVG1M: 29b).
3.12.26x2: [RE not in use]²: This regional ecosystem is not mapped. Melaleuca viridiflora (broad-leaved paperbark) together with Asteromyrtus symphyocarpa (liniment tree) dominate the sparse canopy (4-10m tall). Corymbia novoguinensis is present as part of the canopy or as an emergent tree (6-10m tall) in the Torres Strait islands. Scattered Banksia dentata (tropical banksia), Livistona muelleri, Xylomelum scottianum and Acacia spp. are present as sub-canopy trees. A sparse shrub layer (0.5-3m tall) is present, with mid-dense stands of Asteromyrtus symphyocarpa occurring in some areas. The ground layer is sparse to mid-dense, and dominated by Dapsilanthus ramosus in some areas. Eriachne triseta, Schoenus sparteus and Heteropogon triticeus are consistently present graminoids. Occurs on granite hills on islands. Not a Wetland. (BVG1M: 28c).
Comments 3.12.26: West of Lockhart River and on granite hills on Torres Strait islands. 3.12.26a: West of Lockhart River. 3.12.26b: West of Lockhart River. 3.12.26c: Granite hills on Torres St. Islands. 3.12.26x1: West of Lockhart River. 3.12.26x2: Offshore islands.

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.
