| Regional ecosystem | 3.3.14 |
|---|---|
| Vegetation Management Act class | Least concern |

| Biodiversity status | No concern at present |

| Short description | Melaleuca saligna +/- M. viridiflora, Lophostemon suaveolens woodland on drainage swamps |
| Structure code | Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.3.50c. Woodland to open woodland of Melaleuca saligna (paper bark) +/- Lophostemon suaveolens (swamp mahogany). There is a very sparse to sparse sub-canopy layer and the shrub layer is usually very sparse. In Lakefield National Park a more dense variant occurs which is dominated by Melaleuca leucadendra, with Melaleuca dealbata as a subdominant canopy species. Occurs in drainage swamps, which generally remain flooded in the wet season for many months. Palustrine. (BVG1M: 22b). Vegetation communities in this regional ecosystem include: 3.3.14a: [RE not in use]²: This vegetation community is now mapped as 3.3.50c. Melaleuca saligna (paper bark) usually dominates the sparse canopy (10-18m tall). Lophostemon suaveolens (swamp mahogany) is frequently a codominant canopy tree. Melaleuca clarksonii (hard-barked teatree) is sometimes present as an emergent tree (12-16m tall) in the deepest part of the swamps. Asteromyrtus symphyocarpa usually dominates the very sparse to sparse sub-canopy layer (4-10m tall). Calycopeplus casuarinoides (false casuarina) occurs on the margins of the wettest areas. The shrub layer (0.5-2.5m tall) is usually very sparse and the very sparse to sparse ground layer consists mainly of graminoids. Occurs in drainage swamps, which generally remain flooded in the wet season for many months. Palustrine. (BVG1M: 22b). 3.3.14b: [RE not in use]²: This vegetation community is now mapped as 3.3.50e. Open forest to woodland of Melaleuca leucadendra (weeping paperbark) +/- Lophostemon suaveolens (swamp mahogany) occasionally present in the canopy. M. dealbata is a frequent sub-dominant. Dillenia alata (red beech) and M. leucadendra are frequently present in the very sparse sub-canopy tree layer. The shrub layer ranges from very sparse to mid-dense, and is composed of a variety of shrub species. The ground layer also varies from very sparse to mid-dense cover. Barringtonia acutangula (freshwater mangrove) are often emergent over the deeper open water and aquatic plants such as Eleocharis spp. (spikerush), Nymphaea spp. And Nymphoides spp. Often present. Occurs in perennial swamps scattered through Lakefield National Park. Palustrine. (BVG1M: 22b). |
| Special values | 3.3.14: Potential habitat for NCA listed species: Dendrobium johannis, Fimbristylis adjuncta, Sarcolobus vittatus, Spathoglottis plicata. |
| Fire management guidelines | SEASON: Burn any time after the wet season when sufficiently dry to carry fire, with occasional storm. Avoid late dry season. INTENSITY: Low. INTERVAL: 4+ years. INTERVAL_MIN: 4. INTERVAL_MAX: 50. STRATEGY: Fire management in surrounding ecosystems will assist the prevention of late dry season wildfires which may burn with high intensity. Exclusion of fire not necessary. ISSUES: Avoid peat fires by burning when there is standing water or the ground is water logged. |
| Comments | 3.3.14: Found throughout bioregion. 3.3.14a: Found throughout bioregion. 3.3.14b: This vegetation community occurs in patches too small to be mappable. It is very similar to that of RE 3.2.4 but occurs on swamps on alluvial plains. Lakefield National Park. |
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.
