Red circles drawn on each element of the diagram will assist in following the monitoring
and assessment process throughout the handbook.

The information provided in this handbook is focused on river invertebrate monitoring and
assessment. Other methods are important and complementary.

Fish, diatom and macrophyte techniques are well advanced. The underlying models are generally
modified from the invertebrate assessment techniques described here. These methods are beyond
the scope of this handbook at this time. It is hoped that additional chapters can be added later.
