Soft-shell clams (Mya arenaria) are a dominant intertidal invertebrate in Kejimkujik lagoons where they perform several important ecological functions including stabilizing the mud flat for other benthic organisms, improving water quality, and providing an important food source to several native species, including migrating shorebirds. Monitoring of population structure is necessary to determine whether the clam population is maintaining itself or declining. A pilot study was conducted in 2007 in Little Port Joli Basin to assess the status of the population and determine the cost efficiency of monitoring. This work is performed every 3 years from July to October at the same locations within the productive clam flat area.
