Benthic macroinvertebrates are tiny aquatic creatures, large enough to be seen with the naked eye, but small enough that a microscope is often needed for identification. Some spend all of their life as bottom dwelling organisms (e.g., Scuds), and others spend a portion of their life on land (e.g., Dragonflies and Mayflies). These tiny creatures are the base of the food web upon which most of the fish communities in Fawn River depend.

Throughout the restoration we have collected pre/post grab samples & core samples to reflect the results of the Sand Wand™ restoration. To help us determine and report the size and range of material present – the samples are dried, sieved, weighed and evaluated.
