This dataset contains the workings for deriving salinity condition scores that were generated for the Soil Condition theme of the NSW Monitoring, Evaluation & Reporting (MER) program.

The dataset was generated from 'known saline site' mapping and API activities carried out by DLWC and DIPNR regions between 2000 and 2005. Scores are based on location, size and intensity of salinised areas.

ArcGIS was used to intersect the salinity mapping datasets with the 124 soil monitoring units (SMUs) used for the other Soil Condition theme indicators. The area of each intensity class within each SMU was determined. In cases where it was known that there were errors in the salinity mapping, area values were adjusted accordingly. Intensity as a percentage of total SMU area was then determined.

Salt load and electrical conductivity (EC) impacts on water-ways was evaluated by staff working in the salinity field (expert opinion).
