The habitat of this community is characterised by continuous discharge of groundwater in raised areas of peat. The peat and surrounds provide a stable, permanently moist series of microhabitats. Intact vegetated tumulus springs are only found at four locations. There is a high level of heterogeneity of invertebrate fauna assemblages between these sites, but all are associated with a rich, healthy fauna. Groups commonly represented include Ostracoda, Nematoda, Cladocera, Copepoda, Oligochaeta, Tardigrada, Turbellaria and Insecta.
Typical and common native vascular plant species associated with the tumulus springs are the trees Banksia littoralis, Melaleuca preissiana and Eucalyptus rudis, and the shrubs Agonis linearifolia, Pteridium esculentum, Astartea fascicularis and Cyclosorus interruptus. The following non-vascular plants have also been located on peat mounds associated with the community: Lycopodium serpentium (bog clubmoss), Riccardia aequicellularis, Jungermannia inundata, Goebelobryum unguiculatum and Hyalolepidozia longiscypha.
Common weed species include Isolepis prolifera and Pennisetum clandestinum.
