Management Plan for the Wavyrayed Lampmussel (Lampsilis fasciola) in Canada

The Wavyrayed Lampmussel is a sexually dimorphic, medium-sized freshwater mussel (75-100 mm long) that is easily distinguished from other mussels by its yellow or yellowish-green, rounded shell with numerous thin wavy green rays. This species is considered N1 (nationally critically imperilled) in Canada. The species was downlisted from Endangered to Special Concern under the Species at Risk Act following a reassessment by the Committee on the Status of Endangered Wildlife in Canada in 2010. The Canadian distribution is restricted to southern Ontario; the species is currently found in the St. Clair River delta and the Ausable, Grand, Maitland, Sydenham, and Thames rivers.
