Recovery Strategy and Action Plan for the Eastern Pondmussel (Ligumia nasuta) in Canada
The Eastern Pondmussel is a medium-sized freshwater mussel with an average length of 70 mm. Its shell is slender and long, and bluntly pointed at the posterior end. The outside of the shell varies in colour from yellowish- or greenish-black in juveniles to dark brown or black in adults, with narrow green rays, concentrated at the posterior end of the shell. This species is considered imperilled (N2) in Canada where it has been assessed as Endangered by the Committee on the Status of Endangered Wildlife in Canada and listed as Endangered on Schedule 1 of the Species at Risk Act. The Canadian distribution is restricted to Ontario where it was once one of the most common species in the lower Great Lakes (lakes Erie and St. Clair) and connecting water channels. The current distribution of the species includes the delta area of Lake St. Clair, Lake Erie – including Cedar Creek (Long Point National Wildlife Area (LPNWA)) and Turkey Point Marsh in Long Point Bay as well as McGeachy Pond adjacent to Rondeau Bay, several coastal wetlands of Lake Ontario - Rouge River, Carruthers Creek, Lynde Creek, Consecon Lake, Pleasant Bay, East Lake, Wilton Creek/Hay Bay, and Lyn Creek in the upper St. Lawrence River drainage near the outlet of Lake Ontario.
