Estimated extent1 Pre-clearing 14000 ha; Remnant 2021 11000 ha
Short description Closed heath on seasonally waterlogged sand plains
Structure code Closed Heath
Description Closed or wet heath +/- stunted emergent shrubs/low trees. Characteristic shrubs include Banksia spp. (especially B. robur) Boronia falcifolia, Epacris spp., Baeckea frutescens, Schoenus brevifolius, Leptospermum spp., Hakea actites, Melaleuca thymifolia, M. nodosa, Xanthorrhoea fulva with Baloskion spp. and Sporadanthus spp. in ground layer. Occurs on poorly drained Quaternary coastal dunes and sandplains. Low part of sand mass coastal landscapes where water collects from both overland flow and infiltration from adjoining sand dunes. Palustrine. (BVG1M: 29a).

Vegetation communities in this regional ecosystem include:
12.2.12a: Empodisma minus, Machaerina rubiginosa, Epacris microphylla closed heathland with emergent low shrubs of Leptospermum liversidgei. Occurs on Poorly drained Quaternary coastal dunes and sandplains. Low part of sand mass coastal landscapes where water collects from both overland flow and infiltration from adjoining sand dunes. Palustrine. (BVG1M: 29a).
12.2.12b: Xanthorrhoea fulva wet heathland. Occurs on Poorly drained Quaternary coastal dunes and sandplains. Low part of sand mass coastal landscapes where water collects from both overland flow and infiltration from adjoining sand dunes. Palustrine. (BVG1M: 29a).

Fire management guidelines SEASON: Late summer to winter. INTENSITY: Moderate (to high; due to the inherent characteristics of highly flammable vegetation). INTERVAL: 4-8 years preferred. Vary intervals across space and time to cater for a range of species, e.g. intervals of 1-3 and 8-12 years. INTERVAL_MIN: 1. INTERVAL_MAX: 12. STRATEGY: Aim for a burn mosaic of 40-80%. Ensure planned burn conditions are conducive to maintaining integrity of the landscape (i.e., use good soil moisture, recent rainfall and standing water on the ground). Consider burning progressively as landscape dries out in the same burn season/or across years. Assess regeneration after first growing season and for the next 4 years post-fire to ensure Melaleuca seedlings and lignotubers are not becoming overabundant. ISSUES: The 4-8 year age class for this vegetation type is typically highly productive for shrub flowering and fruiting and provide resources for dependent fauna, such as the ground parrot. Provision of 1-3 and 8-12 year age classes in the landscape nevertheless diversify habitat for a wider range of species. Longer fire intervals of 8-12 years may be desirable if there is a need to counteract the detrimental impacts of a high intensity fire over 100% of landscape. Short intervals are favoured by species such as tiny wattle Acacia baueri, Christmas bells Blandfordia grandiflora and long intervals by wedding bush Ricinocarpus pinifolius, small-leaved geebung Persoonia virgata.
