Transect Data | Water Data

The 2010 survey of Lake Wintergreen found no invasive species in the lake. Fifteen native species were found. The most prominent species was purple bladderwort (Utricularia purpurea). It was found covering most of the northern half of the lake. It was also present in large patches along the eastern shore. The northern half of the lake was the most species rich area of the lake. All fifteen species were found there. Two large patches of western waterweed (Elodea nuttallii) were present. Watershield (Brasenia schreberi) was growing in small to large patches around the entire perimeter of the lake except the middle of the western side. In that area only one species was growing, leafy pondweed (Potamogeton foliosus). The plant was found growing sporadically in medium to large patches around the entire perimeter of the lake. Sevenangle pipewort (Eriocaulon aquaticum), pickerelweed (Pontederia cordata), and white water lily (Nymphaea odorata) were all found in small to medium patches around most of the shore of the lake. Ribbon-leaf pondweed (Potamogeton epihydrus), waterwort (Elatine species), and snailseed pondweed (Potamogeton bicupulatus) occurred in low quantities both in the northern half of the lake and along the western to southern shore. Canadian waterweed (Elodea canadensis), slender naiad (Najas flexilis), marsh primrose-willow (Ludwigia palustris), and coontail (Ceratophyllum demersum) only occurred in small patches in the northern half of the lake.
