We intend to provide an objective account of the history of land condition in two pastoral areas of South Australia - the North-East Pastoral and Marree Soil Conservation Districts (SCDs). We have collected information on historical land condition from a variety of sources. In order to link these diverse forms of information a new methodology was developed for the North-East SCD where each piece of information was assigned to one of five 'land condition' classes. These data were then graphed to elucidate trends over time. For the Marree SCD this approach was unsuccessful due to the size and variability of the area and the relative lack of information. We suggest that this classification technique is useful for gaining information from disparate and imprecise data sources, given sufficient data points.
