What’s wrong with the Australian River Assessment System (AUSRIVAS)?

Abstract: The Australian River Assessment System (AUSRIVAS or AusRivAS) is a national biomonitoring scheme that supposedly assesses the 'biological health' of rivers. AUSRIVAS outputs observed-over-expected (O/E) indices derived from macroinvertebrate survey data obtained both at a site to be assessed and at designated reference sites. However, AUSRIVAS reference sites lack any consistent or quantified status, and, therefore, AUSRIVAS O/E indices have no particular meaning. Moreover, many studies have found AUSRIVAS O/E… Show more

“…The need for implementing biomonitoring programs at different spatial and temporal scales, combined with the fact that many regions worldwide have scarce or absent reference sites and biomonitoring stations, has fostered the development of alternative methods as predictive models [5,[120][121][122][123]. Predictive models are generally based on the reference condition approach (RCA), using the best-known environmental state based on the physical, chemical, and biological habitat [124].…”
