There is an increasingly well-founded understanding of the chief drivers and constraints to widespread adoption by Australian landholders to practices to manage dryland salinity. However, each specific situation depends on a range of biophysical, social and economic factors. Such is the case in this study that examines farmers' salinity management in the Wallatin-O'Brien catchments in the low-medium rainfall zone of the Western Australian wheatbelt. The study involved interviews with landholders and economic modelling of representative farms and salinity management options to gain an understanding of the farmers' adoption behaviour regarding salinity management.Most landholders interviewed saw dryland salinity as a second order farm management issue, due first to the relatively slow rate of expansion of saline land within the catchments and second, because the changes in land use required to prevent further loss of land to salinity were viewed as being uneconomic. The exception to this was the minority (
