Anderson Pond, North Stonington - 2012  

Anderson Pond 2012
  Anderson pond is a 50 acre public pond in North Stonington, CT. There is public boat access on the northeast side of the pond for carry in boats only. The pond's shoreline is intermittently developed with many wooded areas. Our 2012 CAES IAPP survey is a re-survey from 2004, where 18 species were recorded. Our 2012 survey found 26 native aquatic species and three invasive species: fanwort (Cabomba caroliniana), variable-leaf watermilfoil (Myriophyllum heterophyllum), and brittle waternymph (Najas minor). Both fanwort and variable-leaf watermilfoilwere present in the 2004 survey; however, brittle waternymph was only found in 2012.
  The CAES IAPP 2012 survey found considerable differences in invasive species location. In 2004 variable-leaf watermilfoil was the most dominant plant, and fanwort was reserved to two coves in the northern section of the lake. In 2012 fanwort was found to be co-dominant with variable-leaf watermilfoil coating a vast majority of the lake.

  Three native lily pads [watershield (Brasenia schreberi), yellow water lily (Nuphar variegata) and white water lily (Nymphaea odorata)]growing in dense patches throughout the pond above fanwort and variable-leaf watermilfoil. Waterwort (Elatine species)and spikerush (Eleocharis species)were the most prevalent shoreline species, spanning across a bulk of the southern shoreline. Floating-leaf pondweed (Potamogeton natans)was commonly found growing in patches of lily pads around the shoreline and in coves. Four bladderwort species were found including: humped bladderwort (Utricularia gibba), common bladderwort (Utricularia macrorhiza), purple bladderwort(Utricularia purpurea) and floating bladderwort (Utricularia radiata).
