| Short description | Melaleuca viridiflora, Corymbia novoguinensis low woodland on beach ridges |
| Structure code | Low Woodland |
| Description | Melaleuca viridiflora and Corymbia novoguinensis low woodland to tall shrubland +/- Asteromyrtus symphyocarpa +/- M. saligna. Where it occurs as a tall shrubland C. novoguinensis is an emergent. The sparse to mid-dense subcanopy and/or shrublayer contains canopy species +/- Banksia dentata +/-A. brassii. The very sparse to dense ground layer often contains Dapsilanthus spathaceus, Dianella spp. and Lomandra spp. plus a range of grasses including Eriachne spp., Schizachyrium spp. Occurs on beach ridges and dunefields. Not a Wetland. (BVG1M: 28c). Vegetation communities in this regional ecosystem include: 3.2.15a: [RE not in use]²: This vegetation community is now mapped as 3.2.15 and 3.2.17. The sparse canopy (7-9m tall) is dominated by Melaleuca viridiflora (broad-leaved paperbark), Neofabricia myrtifolia (yellow teatree) and Thryptomene oligandra. Scattered emergent Callitris intratropica (cypress pine) (8-11m) are sometimes present. Leucopogon yorkensis dominates the sparse shrub layer (2.5-4m tall), with Alyxia spicata (chain fruit) and Lomandra banksii frequent low shrubs (0.5-1.3m tall). The ground layer is sparse and includes Drosera petiolaris, Stylidium tenerum, Utricularia chrysantha, Schoenus sparteus, Centrolepis banksii, Fimbristylis pauciflora, Dapsilanthus ramosus and Schoenus calostachyus. Occurs on beach ridges. Not a Wetland. (BVG1M: 28c). 3.2.15b: [RE not in use]²: This vegetation community is now mapped as 3.2.17. Woodland (15-18m tall) dominated by Corymbia nesophila (Melville Island bloodwood), Asteromyrtus brassii and Callitris intratropica (cypress pine), with a sparse sub-canopy tree layer (8-10m tall) composed mainly of A. brassii, C. intratropica and M. myrtifolia. Scattered Leucopogon spp. occur in the sparse shrub layer. This variant occurred on the landward edge of the Shelburne Bay dunefields. Occurs in dunefields. Riverine. (BVG1M: 28c). 3.2.15x1: [RE not in use]²: This vegetation community is now mapped as 3.2.17. Asteromyrtus brassii, Neofabricia myrtifolia (yellow teatree) and Allocasuarina littoralis (black sheoak) usually dominate the fairly even, mid-dense canopy (6-10m tall). Multi-stemmed Welchiodendron longivalve (yellow box-penda) trees are also frequently conspicuous in the canopy. A sparse sub-canopy layer (2-6m tall) is frequently dominated by Dodonaea polyandra (native hop-bush) and A. littoralis, while a sparse to mid-dense shrub layer (0.5-1.5m tall) dominated by Alyxia spicata (chain fruit), D. polyandra, Choriceras tricorne or Exocarpos latifolius species is usually present. The ground layer is very sparse with Schoenus sparteus, Cleistochloa spp., Lomandra spp., Alloteropsis semialata, Eulalia mackinlayi and Gahnia aspera being the most frequent species. Occurs on dunefields. Not a Wetland. (BVG1M: 28c). |
| Protected areas | Possession Island NP |
| Special values | 3.2.15: Potential habitat for NCA listed species: Psydrax reticulata. |
| Fire management guidelines | SEASON: August-September up to November depending on the season. INTENSITY: Patchy and low or moderate to high. Fires will tend to burn either with high intensity or at low intensity. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Apply a mosaic across the landscape at a range of intervals to create areas of varying post-fire response. Burn 10-20% of the landscape. ISSUES: These ecosystems typically have a longer fire interval than surrounding vegetation, so it is important to manage fire in surrounding country to avoid too frequent fire. Planned burns in and around heath will assist in breaking up the continuity of fuels across the landscape, preventing late season wildfires which have deleterious ecological effects. |
| Comments | 3.2.15: Was previously mapped as 3.2.15a. Torres Strait Islands. 3.2.15a: Mainland mapped part is now part of RE 3.2.17. Torres Strait mapped part remains as RE 3.2.15. 3.2.15x1: East coast from Shelburne Bay to Usher Point. |
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.
