   CAES IAPP surveyed two unnamed ponds in Pawcatuck, CT. They are accessible only through private property on a piece of land designated for conservation.  The larger pond was about 2.5 acres and is relatively shallow with a maximum depth of 3.0 meters.  The smaller pond is less than 0.5 acres and is spring fed.

  CAES IAPP surveyed the ponds in June, 2011. Thirteen plant species were found in the larger pond. Two of the plants were invasive: Myriophyllum spicatum (Eurasian watermilfoil) and Najas minor (Brittle waternymph).  N. minor was found in small to medium patches close to the shore scattered around the shoreline. M. spicatum was co-dominant with the native species Potamogeton perfoliatus. They were commonly found growing together in large, dense patches in water greater than 0.5 meters where they grew with Utricularia gibba.  Typha species also grew along the majority of the shoreline.  Other native species found include: Ludwigia palustris, Potamogeton bicupulatus, Proserpinaca palustris, Sparganium species, and Callitriche species.

   The smaller pond contained only five species, none of which were invasive.   Nymphaea odorata and Polygonum amphibium were species found in this pond but not the larger pond.  Callitriche species and Ludwigia palustris were also found.
