Set in the heart of Parc national du Bic, Pointe-aux-Épinettes is home to a salt marsh of enormous ecological value.
Salt marshes, natural filters
If lakes and rivers are the Earth’s circulatory system, these wetlands are truly its kidneys.
Salt marshes are important natural filters. Their vegetation decreases current speed and catches materials flowing in the water, making it clearer.
Some plants even capture toxic elements like mercury.
Spartina, improving air quality
Living organisms interact in many ways. Sometimes, to their detriment, but sometimes, these interactions can be beneficial.
In salt marshes, spartina or saltwater cordgrass transfers the oxygen produced by its leaves to even its smallest roots, thereby aerating the soil.
This phenomenon improves the growth of other plants and enables small animals to live in the mud.
