Simply defined, the seashore is the meeting place of land and sea. These dynamic areas can be comprised of sand, mud, shells, pebbles or even hard bedrock substrate. Formed by sediments deposited by ocean currents and sculpted by erosion, our nation’s seashores are some of the most spectacular in the world.

Fluctuating ocean tides provide specialized habitat and feeding grounds for insects, crustaceans, birds and many other animals. Seashores additionally provide a unique opportunity for people to connect with our natural heritage.
