The shorelines are constantly changing, shaped by the waves and weather. How can we make sure our man-made constructions don’t harm this natural process?

On the beach at Penouille, a paved trail formed a dam that prevented the beach from expanding freely. It was replaced by a raised boardwalk so as not to adversely affect the environment and the vegetation has reclaimed its rightful place!

The current and waves repeatedly attack the shore. How does nature protect itself? A fighter is secretly hidden in the salty waters of the St. Lawrence; its name is eelgrass. This aquatic plant forms far-reaching underwater meadows.

Its weapon? A dense network of roots that acts as a shield, preventing the sand from getting washed out to sea. And, its lush foliage slows the moving water, thereby reducing the power of the waves breaking on the beach.

Algae, shells, dead wood… the sea washes all kinds of debris up on shore.

Often considered piles of waste, this debris provides food for many animals. It also prevents the waves from carrying some of the sand off with them. 

However, there’s no reason not to clean the beach of waste left behind by humans. Doing so improves things for vacationers and nature!
