| Short description | Acacia crassicarpa on coastal dunes and beach ridges, woodland to open forest |
| Structure code | Woodland |
| Description | Woodland to open forest of Acacia crassicarpa (spoon tree). Occurs on coastal dunes and beach ridges. Not a Wetland. (BVG1M: 28b). Vegetation communities in this regional ecosystem include: 3.2.5a: Acacia crassicarpa (spoon tree) woodland. Acacia platycarpa (a wattle) and A. torulosa (northern lancewood) may be co-dominant in some areas while Syzygium suborbiculare (lady apple) and Parinari nonda (nonda) are frequent canopy trees. A mixed sparse sub-canopy layer is often present in these clumps. A very sparse shrub layer is often present. The ground layer is short and very sparse to mid-dense and contain Panicum spp. (panic), Heteropogon contortus (black spear grass) or Eragrostis spp. Associated with beach ridges. Not a Wetland. (BVG1M: 28b). 3.2.5b: Low woodland to open woodland dominated by Corymbia clarksoniana (Clarkson's bloodwood) and/or C. novoguinensis and sometimes C. tessellaris (Moreton Bay ash) with subdominants including Acacia crassicarpa (spoon tree), Terminalia subacroptera, Sterculia quadrifida and Syzygium suborbiculare (lady apple). Occurs on coastal dunes and beach ridges. Not a Wetland. (BVG1M: 28b). 3.2.5c: Acacia crassicarpa (spoon tree) open forest, usually with Asteromyrtus brassii and occasionally Melaleuca dealbata (silver-leaved paperbark) and Corymbia novoguinensis. A sparse sub-canopy can contain A. brassii, Acmena hemilampra and Lophostemon suaveolens (swamp mahogany), while Exocarpos latifolius, Dodonaea polyandra (native hop-bush), Halfordia kendack and Breynia oblongifolia are found in the shrub layer. Lomandra banksii is often found in the ground layer with Panicum spp. Occurs on stabilised transgressive dunes. Not a Wetland. (BVG1M: 28b). |
| Protected areas | Possession Island NP, Jardine River NP |
| Special values | 3.2.5: Potential habitat for NCA listed species: Dendrobium bigibbum, Lepturus geminatus. |
| Fire management guidelines | SEASON: Dry season but avoid periods of extremely hot, dry conditions. b: Dry season. INTENSITY: Low, with occasional moderate to high. b: Low to moderate with occasional high intensity. INTERVAL: Interval will depend on fuel loads and seasonal conditions. b: 2-5 years. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Typically self protecting due to low fuel loads and position in the landscape. Burn in association with surrounding landscape, but do not target specifically. b: Burn less than 30% in any year. ISSUES: Fires typically trickle through these vegetation communities because fuel is insufficiently available. Acacia crassicarpa is tolerant to a wide range of fire conditions. b: Need for fuel reduction burns depends on amount of shrub invasion and community structure. |
| Comments | 3.2.5: Extensive along the western Peninsula coast and Torres Strait. 3.2.5a: Often dense clumps occur which are separated by wide treeless areas. A variant on dunes in Princess Charlotte Bay is a Corymbia tessellaris dominated shrubby woodland. Melaleuca nervosa (fibre-bark teatree) and Terminalia muelleri (damson) occurs frequently in the canopy. Most extensive on the west coast, but also on the east coast and the Torres Strait. 3.2.5b: Torres Strait. 3.2.5c: Western islands of Torres Strait. |
