Bissonette Pond, Willington
Bissonette Pond is a 48.5-acre lake in
Our August 2006 survey found 20 species of plants and no invasive species. The most abundant plant is watershield (Brasenia schreberi), a plant with floating leaves which was abundant in most inlets. The other floating-leaved species, yellow water lily (Nuphar variegata) and white water lily (Nymphaea odorata), were found in much smaller patches intermingled with the watershield.
Flat-Leaf bladderwort (Utricularia intermedia), humped bladderwort (Utricularia gibba), common bladderwort (Utricularia macrorhiza), large-leaf pondweed (Potamogeton amplifolius), floating-leaf pondweed (Potamogeton natans), and charaphyte (Chara) were found growing together in patches along edge of the lake. Similarly, small pondweed (Potamogeton pusillus), floating bladderwort (Utricularia radiata), and ribbon-leaf pondweed (Potamogeton epihydrus) coexisted in several shallow areas. The shoreline of the pond is host to long patches of American bur-reed (Sparganium americanum) which is joined in one area on the eastern shore by sedges.
Needle spikerush (Eleocharis acicularis) occurred with a large patch of humped bladderwort on the end of an outcropping on the western shore. Likewise clasping-leaf pondweed (Potamogeton perfoliatus) was only found once, in a small patch on the southern shore. A small patch of sevenangle pipewort (Eriocaulon aquaticum) is located in the southern-most cove.
