Submerged Plant Growth

Three species of submerged plants were found during collections in 2013, with an additonal found in the 2016 survey. Canada rush was found south of Sears Island, where as it was not found before. From our data, Eurasian milfoil was identified as an invasive species. The two most present plants, Eurasian Watermilfoil and Small Pondweed were found in relatively equal quantities in 2013. In 2016, it was noticed that milfoil is spreading, while pond weed in being out competed. One of these plants, Najas, was only found in one location during 2013, which was not found in 2016. It should also be noted that those points where more than one plant was collected were recorded twice, once for each plant that was collected. These plants were all located in relatively shallow areas with little current flow and high floor level silt content. While the locations of plant growth should stay consistent, summer collections will reveal much denser collections of both Eurasian Watermilfoil as well as Small Pondweed. As the water becomes warm enough, the plants will grow back up into the water column to attain nourishment, resulting in much denser collections.
