Inundation and edaphic factors are considered to be the primary factors controlling the distribution of tree species at Lake Toolibin, an ephemeral freshwater lake situated in the Central Wheatbelt of Western Australia. Clearing of the catchment surrounding the lake for agriculture has led to changes in the hydrology, causing increased runoff, higher groundwater levels and mobilization of sub-soil salt stores. Thus higher groundwater and subsequent salt accumulation in surface soil during periods of lake dryness (NARWRC 1978). Both prolonged flooding and increased soil salinity are believed to affect tree vigour at Lake Toolibin. The aims of this study were to determine vegetation patterns and their relationships to soil salinity and inundation, and to elucidate possible causes of recent tree mortality.
