This poster is a fantastic resource to use during macroinvertebrate sampling sessions to demonstrate the five habitats that exist within a waterway; on the surface (surface zone), in open water (deep zone), amongst vegetation (reed zone), on rocks/logs/gravel (substrate zone) and amid the sediment (benthic zone).  Use the links below to each quarter of the poster to print as A3, laminate and join for a class-size poster you can keep.

Use the information on the reverse of the  Waterbug Cards to have students place them in their correct habitat on the poster.
