| Short description | Corymbia novoguinensis and/or C. clarksoniana woodland in coastal areas |
| Structure code | Woodland |
| Description | Corymbia novoguinensis and/or C. clarksoniana (Clarkson's bloodwood) woodland to open forest, occasionally with Acacia crassicarpa (spoon tree) +/- Melaleuca spp. A very sparse to mid-dense lower tree layer can commonly include A. crassicarpa, Parinari nonda (Nonda plum) and Syzygium suborbiculare (white apple), with Melaleuca viridiflora (broad-leaved teatree), Neofabricia myrtifolia (yellow teatree) and Asteromyrtus spp. occasionally present. The very sparse to mid-dense shrub layer also usually contains Acacia spp., with Alyxia spicata (chain fruit), Exocarpos latifolius, Lomandra banksii and Leucopogon spp. occasionally present. The sparse to dense groundlayer commonly contains Dianella spp., Heteropogon triticeus (giant spear grass), Lomandra spp., Panicum spp. and Schizachyrium spp. (fire grass). Occurs on dunes. Not a Wetland. (BVG1M: 9e). Vegetation communities in this regional ecosystem include: 3.2.7a: Corymbia novoguinensis and/or C. clarksoniana (Clarkson's bloodwood) woodland to open forest, occasionally with Acacia crassicarpa (spoon tree) +/- Melaleuca spp. A very sparse to mid-dense lower tree layer can commonly include A. crassicarpa, Parinari nonda (Nonda plum) and Syzygium suborbiculare (white apple), with Melaleuca viridiflora (broad-leaved teatree), Neofabricia myrtifolia (yellow teatree) and Asteromyrtus spp. occasionally present. The very sparse to mid-dense shrub layer also usually contains Acacia spp., with Alyxia spicata (chain fruit), Exocarpos latifolius, Lomandra banksii and Leucopogon spp. occasionally present. The sparse to dense groundlayer commonly contains Dianella spp., Heteropogon triticeus (giant spear grass), Lomandra spp., Panicum spp. and Schizachyrium spp. (fire grass). Occurs in wet coastal areas usually associated with dunefields. Not a Wetland. (BVG1M: 9e). 3.2.7b: Corymbia papuana, C. clarksoniana woodland on old dunes. Occurs on degraded dunes along the edge of Tertiary plateau. Not a Wetland. (BVG1M: 9e). |
| Protected areas | Wuthathi (Shelburne Bay) NP (CYPAL), Bromley (Ampulin) NP (CYPAL), Apudthama NP (CYPAL), Possession Island NP |
| Special values | 3.2.7: Potential habitat for NCA listed species: Acacia solenota. |
| 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: 1-5 years. INTERVAL_MIN: 1. 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 | 3.2.7: parts of RE 3.2.8 was amalgamated into this RE. Occurs on dunes on the east coast and the Torres Strait. 3.2.7b: West coast of the bioregion, specifically in the Archer river area on APN lands. |
