| Structure code | Open Sedgeland |
| Description | Baloskion tetraphyllum and/or Leptocarpus spp. and/or Dapsilanthus spathaceus open sedgeland to sedgeland. Asteromyrtus lysicephala, Nepenthes mirabilis, Utricularia spp., Drosera spp. (sundew), Selaginella spp., Pseudolycopodiella spp., Lateristachys spp., or Palhinhea spp., may also be common. A. lysicephala, Melaleuca spp., Banksia dentata and Pandanus spp. Can occur as emergents. Occurs on drainage swamps. Palustrine. (BVG1M: 34c). Vegetation communities in this regional ecosystem include: 3.3.64a: [RE not in use]²: This vegetation system is now mapped as 3.3.64. Baloskion tetraphyllum is a consistent graminoid, and forms a conspicuous ground layer (50-80cm tall) with a variety of other species. Anthelepis undulata, Dapsilanthus spp., Isachne confusa, Eriocaulon spp., Schoenus sparteus and Fimbristylis spp. are frequent graminoids. Nepenthes mirabilis (Pitcher plant), Utricularia spp., Drosera spp. (sundew), Selaginella spp. And Pseudolycopodiella spp., Lateristachys spp., or Palhinhea spp. Are distinctive forbs frequently present in this unit. In places, Gahnia sieberiana (saw sedge) dominates forming a mid-dense ground layer (1.0-1.2m tall). Very scattered emergent shrubs (0.5-6m tall) may be present with Asteromyrtus lysicephala (back to front bush) occurring at the greatest densities. Emergent Pandanus spp. (7-9m tall) are present in some areas. Occurs on drainage swamps in dunefields. Palustrine. (BVG1M: 34c). 3.3.64b: [RE not in use]²: This vegetation community is now mapped as 3.10.20a. Gahnia sieberiana (saw sedge) dominates the sparse to mid-dense shrub layer (1-2m tall). Other frequent shrub species are Asteromyrtus lysicephala (back to front bush), Banksia robur (swamp banksia), Melastoma malabathricum subsp. malabathricum and Melaleuca polandii. Sparse emergent shrubs (2-4m tall) include Pandanus spp., Grevillea pteridifolia (toothbrush grevillea), Melaleuca quinquenervia (broad-leaved paperbark), Xanthorrhoea johnsonii (grass-tree), Baeckea frutescens (weeping baeckea) and Leptospermum polygalifolium. These swamps receive fairly continuous seepage from the surrounding sandstone areas throughout the year. Occurs on raised swamps on sandstone tablelands. Palustrine. (BVG1M: 34c). 3.3.64c: [RE not in use]²: This vegetation community is now mapped as 3.10.20b. Sticherus spp. dominates the dense ground layer (1-2m tall), with Gleichenia sp. and Lindsaea sp. being other frequent fern species. Bromheadia pulchra, Dendrobium lobbii, Isachne confusa and Baloskion tetraphyllum subsp. Meiostachyum are frequent graminoids. Scattered shrubs (1-2.5m tall) are sometimes present and include Asteromyrtus lysicephala (back to front bush), Baeckea frutescens (weeping baeckea), Gahnia sieberiana (saw sedge) and Melastoma malabathricum subsp. Malabathricum. Emergent Asteromyrtus brassii, Dillenia alata (red beech), Neofabricia myrtifolia, Welchiodendron longivalve (yellow box-penda) and Xanthostemon crenulatus (4-5m tall) are sometimes present. Occurs in spring-fed, sheltered gorges in sandstone ranges. Palustrine. (BVG1M: 34e). 3.3.64x1: [RE not in use]²: This regional ecosystem now mapped as 3.3.64. Closed grassland of Isachne spp. and Schizachyrium spp. with variety of sedge species. Occurs on broad drainage depressions. Occurs on broad drainage depressions. Palustrine. (BVG1M: 34a). |
| Protected areas | Apudthama NP (CYPAL), Bromley (Ampulin) NP (CYPAL), Olkola NP (CYPAL), Cape Melville NP (CYPAL), Oyala Thumotang NP (CYPAL) |
| Special values | 3.3.64: High diversity of sedges. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not target for burning. Burn in association with surrounding landscape. ISSUES: Avoid peat fires by burning when there is standing water or the ground is water logged. Burn surrounding country when substrate is moist or there is standing water. |
| Comments | 3.3.64: Includes Isachne spp. and Schizachyrium spp. tussock grasslands with variety of sedge species on broad drainage depressions found on streams draining east out of the Kimba plateau. Most extensive in the Jardine Swamps in the north. 3.3.64b: East and north of Cape Flattery. 3.3.64c: Sandstone ranges of the Richardson Uplands. 3.3.64x1: Restricted to drainage patterns on the eastern edge of the Kimba Plateau. |
1 Estimated extent is from version 13.1 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.
