The Overlooked Snails

Snails are important components of ecosystems. They contribute to carbon flow, which in turn contributes to energy flow in ecosystems. While some snails in aquatic environments feed primarily on algae, land species can feed on carrion, fruit, mushrooms, and some are even carnivorous. Others help in the breakdown of leaf litter and fallen trees. They are also important sources of food for many animals. To better understand the aquatic snails of Pennsylvania, WPC has initiated a multi-year study of springs, streams, lakes, wetlands, and reservoirs. A variety of snails can be found in Lake Pleasant in Erie County.
