Chenopod shrublands and Samphire shrublands
- Overstorey is dominated by a range of hardy low shrub species.
- Widespread in the near-estuarine, arid and semi-arid areas and occur generally as extensive flats.
- Site conditions tend to affect the type of shrub species that occur within these communities.
- In damp and water logged areas (e.g. on drainage areas and fringing salt lake areas) samphires dominate the overstorey.
- Plants in samphire communities include the Chenopodiaceae genera Halosarcia, Salicornia, Sclerostegia and Sarcocornia.
- Species in chenopod communities are drought and salt tolerant and include the Sclerolaena, Atriplex (salt bush), Maireana (blue bushes, cotton bush), Chenopodium and Rhagodia genera
Generally these communities have remained intact since European settlement. In some cases the communities have increased in extent because of increased salinity and waterlogging. Foremost among threats for coastal occurrences are infilling for urban areas, changes to tidal regimes and isolation from the estuary by roads and infrastructure.
