RMI Underlay Mats

Did you know you can get a handy underlay map to place beneath the segmented tray in your Riverfly kit? It’s perfect for helping you sort the invertebrates in your sample into the eight groups counted in the Riverfly Monitoring Initiative.

Riverfly trainer and volunteer Dr. Richard Osmond has produced this waterproof underlay mat, available to buy from his website here.

Alternatively, the Riverfly Partnership has a downloadable mat that you can print off, stick together and laminate yourself. Click here to download the 4 × A4 version, or here if you have an A3 printer.
