Recovery Strategies

Recovery Strategy and Action Plan for the Mapleleaf (Quadrula quadrula) in Canada (Great Lakes – Western St. Lawrence Population)

The Mapleleaf is a medium-sized (up to 12 cm) member of the freshwater bivalve family Unionidae. The shell is approximately square in outline, relatively thick and displays colour variations ranging from yellowish green to light brown in juveniles, and greenish brown to dark brown in older individuals. Typically, two rows of raised nodules extending in a v-shape from the point of shell union (umbo or beak) to shell edge (ventral margin) distinguish the outer shell surface of this bivalve species, while the interior (nacre) of the shell is white.
