Phytosociology of coastal salt-marshes in the mediterranean climatic region of Australia
Bridgewater, P. B.
Vegetation from coastal salt-marshes in that part of southern Australia with a mediterranean-type climate can be classified into a number of associations from three classes. Some synsystematic units have a wide distribution from Victoria to Western Australia. These are invariably pioneer associations. Associations typical of established salt-marshes tend to be more restricted in their distribution. A major centre of diversity for salt-marsh vegetation is seen to be South Australia, particularly the Coorong region. This region also marks a major boundary between some higher level synsystematic units. Climatic factors, particularly the relationship of summer aridity and winter rainfall are postulated as the major environmental controls for alliance and class distribution, with topography and salinity as the controls at individual localities.
