The Paul Caissie Trail travels through a field passing by two man-made ponds. On my hike there were two geese that left the ponds and crossed over to the field in front of me. They honked at me in annoyance as I passed. The trail enters a hardwood forest before coming out into a clearing by the bay. There is an outhouse, picnic table and fire pit in the clearing. The far end of the clearing is a strip of tall grass separating the clearing from the salt marsh. Near the long grass is an interpretive sign and small lookout platform.

The salt marsh is the main feature of this trail. The salt marsh extends out into the bay to a sand dune. The marsh is full of small ponds. You should see many great blue herons and ducks in these ponds.

To get to the trail, take Route 530 from Route 134 in Grande-Digue (near the hardware store). Drive for 2.6 kilometres and turn right to stay on Route 530. Drive for another 2.1 kilometres and turn into the second driveway for Joe Caissie Seafood on the right. Drive back the road to the left of the building. Just before you come to a strip of trees you will see a strip of grass and parking signs on the left. Park here. The trail continues in the grass next to the driveway.

From the Sign

The Salt Marshes

The Salt Marshes sign

In Grande-Digue, there is a coastal habitat, composed of aquatic and terrestrial environments, which makes the transition between the sea and non-coastal land.

The salt marshes are flooded by sea water, following the daily rhythm of the tides. When the tide does not cover them, as the soils remain saline, the grasses and small shrubs found there must be able to tolerate salt water.

Environments whose picture has changed several times over the past two centuries...

Marshes have long been seen as smelly lands (smells of decomposing vegetation), which were avoided or sought to be "improved" by draining them, for example to harvest hay, or, more recently, by backfilling them for construction.

We now recognize their role in the filtration of water (pollutants, pesticides) that reaches the coast and the sea, in the protection against erosion and flooding during storms, and as a habitat for many plant and animal species ( some of which have protected status, or are of commercial importance, particularly for fishing).

The richness in nutrients allows high plant productivity. Insects, worms, mammals, fish, molluscs, crustaceans and birds find refuge there or come to enjoy the abundance of food.

Marshes also store significant amounts of carbon in their soils, which helps to mitigate global warming!
