Plankton (microscopic free floating organisms) are a very important aspect of the ecology of the lakes within the Glen Lake/Crystal River Watershed. This video highlights the method by which the plankton are collected in our lakes using a plankton net along with locations in our watershed where we collect the plankton and how often they are collected. The plankton samples are analyzed in the laboratory using a compound microscope. We especially look for a rich biodiversity and whether we are encountering any invasive species. This video features Laura Wiesen and Rob Karner as the plankton peeps who do the collecting and analyzing.
