A direct gradient analysis of averaged edaphic data for 0 - 60 cm pedon depth of twelve highly salinized, waterlogged and relatively undisturbed sites of Hyderabad District (Sindh), Pakistan, was performed through Principal Components Analysis in order to determine the main directions of compositional variation of the edaphic environment and the relationship between the vegetation pattern and the environmental complex. The first principal component was largely governed by salinity and clay contents, the second component correlated with available P and silt content and the third component associated with sulphate content and pH. The distribution behaviour of Salvadora persica, Tamarix indica, Suaeda monoica, Suaeda fruticosa and Cressa cretica along the gradients is examined.
