| Short description | Lophostemon suaveolens woodlands on creeklines and swamps |
| Structure code | Open Forest |
| Description | Lophostemon suaveolens (swamp mahogany) woodland to sometimes open forest +/- Melaleuca spp. (paperbarks). Xanthostemon crenulatus (penda) sometimes occurs as a codominant. Lower tree layers and shrub layers are very sparse to mid-dense and include canopy species +/- Banksia dentata (tropical Banksia) +/- Acacia spp. (wattles). Occurs on streamlines, swamps and alluvial terraces. Riverine. (BVG1M: 22b). Vegetation communities in this regional ecosystem include: 3.3.9a: Lophostemon suaveolens (swamp mahogany) woodland to sometimes open forest +/- Melaleuca viridiflora (broad-leaved tea-tree) +/- Parinari nonda (Nonda plum). Where they occur Syzygium angophoroides (swamp satinash) and Melaleuca stenostachya (fibre-barked tea-tree) can be co-dominant. Lower tree layers and shrub layers are very sparse to mid-dense and include canopy species +/- Banksia dentata (tropical Banksia) +/- Acacia spp. (wattles). The ground layer is sparse to dense and can include Aristida spp., Panicum spp. and Heteropogon triticeus (giant spear-grass) as well as fern species and a range of sedges and hydrophilic forbs. Occurs on streamlines, swamps and alluvial terraces. Riverine. (BVG1M: 22b). 3.3.9b: Xanthostemon crenulatus (penda), Lophostemon suaveolens (swamp mahogany), Asteromyrtus brassii woodland to open forest +/- Dillenia alata (red beech) +/- Melaleuca saligna (paperbark). The low sparse sub-canopy contains canopy species +/-Melicope elleryana (pink Evodia) +/- Banksia dentata (tropical Banksia) +/- Acacia spp. (wattles). A very sparse to sparse shrub layer contains juvenile canopy species and Melastoma malabathricum subsp. Malabathricum. The ground layer is sparse and can include Gahnia sieberiana, Nepenthes mirabilis (pitcher plant) and a range of sedge and fern species. The ground layer often includes sedge species, ferns and hydrophilic forbs. Occurs in broad drainage depressions. Palustrine. (BVG1M: 22b). |

| 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: 3-5 years. INTERVAL_MIN: 3. 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. Late fires and too frequent fire management in gallery forests may reduce development of fire sensitive non-eucalypt species and reduce numbers of large and medium sized trees. |
| Comments | 3.3.9: Occurs throughout the bioregion but more common in northern areas. 3.3.9a: Usually occurs in seepage areas. Occurs throughout the bioregion but more common in northern areas. 3.3.9b: This community often occurs in the top of shallow drainage systems off plateaus and often grades into the denser 3.3.9a further down the gradient as the depression become wetter and more swampy in seepage areas. This description replaces another community originally mapped as 3.3.5b, which is now part of 3.3.6. Mainly found on headwaters of streams flowing off the Kimba Plateau, but can occur elsewhere in the bioregion. |
