Purpose

This data set assists with state and regional planning to define the spatial variation of land according to the parameters of geomorphology, lithology, landform and climate, with dependent variables of soil and vegetation types. Other interpreted data tagged to the land systems includes the hazard potential, ie. inherent susceptibility to various forms of land degradation, and the 'potential productivity'. The maps and land system descriptions are drawn from an uneven database of some 28 individual studies of the land and additional unpublished data, with varying levels of detail and reliability. The land system descriptions are presented as a single line that masks the considerable variation in each land system -- each land system is treated as essentially a single point entity, when in reality it is a complex of land types with a known range of variation. While this is appropriate for some purposes, it is not suitable for all uses, and should be used with care. Potential users not familiar with the land system concept are encouraged to contact the custodian for advice and assistance. Interpretations are of the inherent susceptibility of the land to degradation and do not adequately represent hazards (which involves considerations of land use) which will be of interest to most users. Rowan's initial report, paper maps and transparencies are now considerably out of date following extensive error checking and subsequent revision. While the initial report was never formally released, the revised and expanded Edition 2 is in an advanced stage of preparation and should be released in 1994/95.
