Extended Riverfly Training - Autumn 2025

This Extended Riverfly Training has been designed for existing Riverfly monitors who are already confident in the basic ARMI method.

During this indoor session, you will be presented with all 33 target groups of the Extended Riverfly Method, and advised when is best to carry out this method to complement the standard monthly ARMI surveys.

After presentations, you will be given trays of pre-collected live specimens to sort into as many of the groups as possible, following which you will undertake an informal ‘test’ at the end of the session.

Those passing the test will be certified as Extended Riverfly surveyors, whereas those not quite reaching the required scores will simply be welcomed to our next training session to continue developing your identification skills.
