Soil Landscape Regolith Stability of North-East New South Wales

Linework based on reconnaissance and soil landscape coverage was created as a result of modifications and updates made to the original Soil and Regolith Attributes for the CRA/RFA Model Resolution (Upper North-East and Lower North-East CRA Regions, DLWC 1999) and includes new linework in some areas and complete re-tagging of map units. ; ; This linework delineates soil landscapes for the entire Upper North-East and Lower North-East CRA Region, including the Singleton 1:250 000 map sheet. The attribute data for each soil landscape unit is described in a linked Microsoft Access database Soil Landscape Regolith Stability for North-East New South Wales and contains information on soil and landscape properties and limitations which are useful in planning for sustainable land use. ; ; The coverage contains a regolith stability class (soil erodibility), which is broken up into four classes (1-4). A regolith stability classification consists of a dominant class and up to three sub-dominant classes (if necessary), for example, R1(3,4), where R1 is the dominant regolith stability class and (3,4) are the sub-dominant regolith stability classes.
