Hansens Pond, Mansfield
Hansens Pond is a 43.6-acre waterbody located in Mansfield, CT. The shoreline is primarily forested and there is no public boating access. The shallow nature of the pond combined with a mucky bottom provides favorable conditions for aquatic plant growth.
Our 2014 IAPP survey found the invasive species variable-leaf watermilfoil (Myriophyllum heterophyllum) and water chestnut (Trapa natans) and ten native species in the pond. Variable-Leaf watermilfoil occurred in small patches around the edge of the pond while water chestnut occurred only on the western shore. The most dominant native plants were yellow water lily (Nuphar variegata) and white water lily (Nymphaea odorata) which sprawled throughout the entire waterbody and covered the northern portion of the pond. There were three pondweeds present mainly in the eastern cove of the pond: large-leaf pondweed (Potamogeton amplifolius), ribbon-leaf pondweed (Potamogeton epihydrus), and small pondweed (Potamogeton pusillus). Other native species found throughout the pond were watershield (Brasenia schreberi), bur-reed (Sparganium species),and common bladderwort (Utricularia macrorhiza).
