About the report

The overall aim of this document is to assist in estimating the power of certain types of monitoring programs to detect changes that might result from artificial disturbances ie 'environmental impacts'. The issues involved, both statistical and ecological/environmental, are complex. Further discussion of these issues can be found in Monitoring Ecological Impacts: Concepts and Practice in Flowing Waters (Downes et al 2002). The analytical approach adopted here is the analysis of variance. For information on this recent books by Quinn & Keough (2002) and Underwood (1997) are recommended. These are listed in the references.
