Amos Lake, Preston - 2006
Our survey conducted in August 2006 found Myriophyllum heterophyllum X laxum as the only invasive plant species. The dominant submerged species was Potamogeton robbinsii, which was found almost continuously around the perimeter of the lake. Nymphaea odorata was the most abundant floating-leaved plant, found in most protected coves and along the western shoreline.
Surrounding the point on the western shoreline was abundant Potamogeton gramineus and Potamogeton robbinsii. The north-western shoreline is dominated by Nymphaea odorata and Potamogeton robbinsii, with some small patches of Nuphar variegata. Further north are sizeable patches of Sagittaria sp. and Potamogeton robbinsii as well as an isolated patch of Myriophyllum tenellum. The northern-most point contains sparse Potamogeton robbinsii and Utricularia gibba. The north-eastern shore contains a mixture of Potamogeton robbinsii, Sagittaria sp., Nymphaea odorata and Potamogeton pulcher.
The southern half of the lake contains several very diverse aquatic plant communities in the coves. Two coves, towards the center of the lake on opposite shores, east and west, contain large amounts of Nymphaea odorata, Nuphar variegata, Brasenia schreberi, Potamogeton robbinsii, Potamogeton gramineus, Utricularia purpurea, Glossostigma cleistanthum, Utricularia vulgaris, and Najas flexilis . In addition, the cove on the west shore contains small amounts of Utricularia radiata and Ceratophyllum demersum, and a sizeable patch of Myriophyllum heterophyllum x laxum.
Further to the south-east there are two inlets containing small amounts of all Potamogeton epihydrus, Pontederia cordata, Potamogeton robbinsii, Utricularia vulgaris, Potamogeton pulcher, and Utricularia purpurea.
The southern-most cove area is flanked by a recreational vehicle park with a swimming area, containing Potamogeton robbinsii, Pontederia cordata, Nymphaea odorata, Najas flexilis, Potamogeton gramineus, and very small amounts of Potamogeton pulcher and Glossostigma cleistanthum.
