In August 2013, the CAES IAPP conducted a vegetative survey of a 1 acre pond located on private property in Clinton, CT. It is a small, shallow pond with a maximum depth of 4 meters. Access to the pond is limited to the resident’s backyard for personal use.
The survey found 12 plant species, none of which were invasive. Brasenia schreberi (watershield), Nymphea odorata (white water lily), and Utricularia radiata (Little floating bladderwort) dominated the pond except for an open area where the water depth was too deep to support plant life. Of the ten transect points, B. schreberi and N. odorata were present on 50 % and U. radiata was present on 20 %.
A few other species that were prominent in the pond included: Nuphar variegata (yellow water lily), Potamogeton natans (broad-leaved pondweed), and Pontederia cordata (pickerelweed). N. variegata was found throughout the pond in several patches, with a large patch on the eastern side. P. natans was found in a large patch on the northeast side along with a few small patches along the southern and western shoreline. P. cordata was found in a large patch on the eastern side with a few small patches on the northeast shore as well as the southern shore.
The eastern to southeast portion of the pond is especially difficult to navigate as it was extremely shallow and filled with plants.
