AUSRIVAS Macro

AUSRIVAS (Australian River Assessment System) is a rapid prediction system used to assess the biological health of Australian rivers. These models predict the aquatic macroinvertebrate fauna expected to occur at a site in the absence of environmental stress, such as pollution or habitat degradation, to which the fauna collected at a site can be compared. Thus, AUSRIVAS produces a biological assessment that can be used to indicate the overall ecological health of the site.
