About the manual
Two groups of sites were sampled during the program: reference and test sites. Reference sites were those "least-disturbed" sites that were sampled to provide the database used to generate the predictive bioassessment models. These sites represent minimally impacted areas that have not been significantly altered by human activities. They are equivalent to the notion of "best available condition" discussed in Reynoldson et al. (1997) and the process used to select reference sites is detailed in Anon (1994).
In South Australia, 23 drainage basins from five drainage divisions were selected as having sites suitable for inclusion in the study. The basins provide a wide coverage of the geographical and meteorological variation that occurs within the State, and the chemical nature of many surface waters from these basins has already been described (Glatz 1985). Some drainage basins in South Australia have no true riverine systems present within defined channels (e.g. Nullarbor, Gairdner, Mallee) and as such were not included in the program.
