Regional ecosystem 11.2.3
Vegetation Management Act class Of concern

Biodiversity status Of concern
Subregion 14, 1, 2, (7.1)
Estimated extent1 Pre-clearing 3000 ha; Remnant 2021 2000 ha
Short description Microphyll vine forest ("beach scrub") on sandy beach ridges and dune swales
Structure code Closed Forest
Description Microphyll/notophyll vineforest to semi-deciduous vine thicket on Quaternary coastal dunes. Commonly consists of several of the following trees: Pleiogynium timorense, Mimusops elengi, Cupaniopsis anacardioides, Exocarpos latifolius, Sersalisia sericea and Diospyros geminata. In dry, exposed and windswept locations, this RE may only reach 4-5 m, and include deciduous emergent species such as Gyrocarpus americanus and Brachychiton australis. At its best development this formation grows to 15 m and includes further species such as Ficus virens, Aglaia brownii, Polyalthia nitidissima, Canarium australianum, Miliusa brahei and Ficus spp. A shrub layer may be present with Carissa ovata, Capparis sepiaria, Eugenia reinwardtiana, Drypetes deplanchei and Aidia racemosa. Vines are common, including Cynanchum viminale subsp. australe, Jasminum didymum, J. simplicifolium, *Abrus precatorius and Cissus spp. A ground layer is sparse or absent. Occurs on Quaternary coastal dunes and adjacent swales. Best developed on secondary dune swales and areas protected from strong winds. Soils are fine to coarse beach sands possibly enriched by calcareous sediments. Not a Wetland. (BVG1M: 3a).

Special values 11.2.3: Potential habitat for NCA listed species: Xylosma ovata.
Fire management guidelines INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: This vegetation requires protection from wildfire. Protection primarily relies on broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. Maintenance of fire breaks may be appropriate on flat country, but natural features will be useful as breaks in 'wild' country. ISSUES: Fuel reduction burning in the surrounding vegetation under low fire danger conditions and/or revegetation of cleared areas reduce the risk of damaging wildfires. Exotic grasses, such as Guinea grass and Buffel grass, can fuel fires that carry into and damage vine thickets. Maintain or re-establish native vegetation communities adjacent to this ecosystem. Herbicide control of exotic grasses, or short term grazing, on the edge of vine thickets will reduce the risk of wildfires damaging vine thickets.
Comments 11.2.3: Occurs usually as a narrow community immediately adjacent to RE 11.2.2 or RE 11.2.5. Widespread between the Fitzroy River and Townsville, but highly localised. Reaches best development between Station Creek and the Elliot River, S. of Cape Upstart. Prone to weed invasion in some areas, particularly by *Cryptostegia grandiflora (rubber vine), *Ziziphus mauritiana (Chinee apple) and *Acacia nilotica (prickly Acacia), and is subject to clearing for coastal development. Areas within the Bowen district are particularly heavily infested with non-native species.
