| Structure code | Sedgeland |
| Description | Sedgelands, fernlands and closed heathlands associated with springs on sandstone tablelands. RE defunct. Palustrine. (BVG1M: 34c). Vegetation communities in this regional ecosystem include: 3.10.20a: Gahnia sieberiana and Asteromyrtus lysicephala shrubland to open sedgeland Banksia robur. Emergent Melaleuca quinquenervia and Pandanus spp. usually occur. A mid-dense groundlayer is often dominated by Baloskion tetraphyllum and a range of other sedges. Associated with drainage swamps on elevated sandstone plateaus. Palustrine. (BVG1M: 34c). 3.10.20b: Sticherus spp. (shield ferns) closed fernland but also including Gleichenia spp. (coral ferns) and Lindsaea spp. (necklace ferns). Other species that may occur include Bromheadia pulchra, Dendrobium lobbii, Isachne confusa and Baloskion tetraphyllum. Scattered Asteromyrtus spp., Dillenia alata (red beech) or Neofabricia myrtifolia often occur as emergents shrubs or low trees. Occurs in spring-fed, sheltered gorges in the sandstone ranges of the northern Cape York Peninsula. Palustrine. (BVG1M: 34e). |
| Protected areas | Cape Melville NP (CYPAL) |
| Special values | 3.10.20: Potential habitat for NCA listed species: Dallwatsonia felliana, Spathoglottis plicata. 3.10.20a: High diversity of sedges. In sheltered gorges, closed fernlands dominated by Sticherus sp. with Gleichenia sp. and Lindsaea sp. occur. |
| 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: Fire sensitive vegetation type. 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 | 3.10.20: This RE is a point coverage included in the Spring database.Vegetation communities associated with these springs may not mappable at 1:100 000 scale. This RE may also include communities associated with springs found on land zone 5 and 7. 3.10.20a: These swamps receive fairly continuous seepage from the surrounding sandstone areas throughout the year. Vegetation communities associated with these springs may not mappable at 1:100 000 scale. This RE may also include communities associated with springs found on land zone 5 and 7. Occurs on sandstone tablelands to the west and south of Cape Flattery. 3.10.20b: Vegetation communities associated with these springs may not mappable at 1:100 000 scale. This RE may also include communities associated with springs found on land zone 5 and 7. Occurs in sheltered gorgers in sandstone ranges of the Richardson Uplands. |
